The cursor position indicator shows the distance and attenuation from the start of the fiber to the point that the cursor intersects with the trace. It also indicates when the cursor is in the zone preceeding an event, the number and characteristics of this event.

Positioning A and B cursors

To accurately position a cursor it is often easier to first zoom-in on the display (refer to “Zoom-in” page 41).

To move a cursor, select it and drag it with the mouse, or click on the position you want.

Cursor selection To make the cursor selection easier, use the option Cursor Mode in the Display menu.

– Cursor «Auto»: the active cursor is the closest one of the current cursor. Directly click on the display window allow you to immedi-ately move the active cursor. This option allows you to move either the right or left cursor.

– Cursor «A / B» : this option is used to exclusively move the A / B cursor.

– Cursor «A + B» : move the both cursors simultaneously, without modifying their distance.

Tooltips The current cursor is associated with a Tooltips (activated in the Dis-play > Preferences ... menu) which gives the coordinates of the point of the trace showed by the current cursor, as well as the direction of the A and B cursors. The active cursor is underlined.

When you click on the cursor or when the focus stays more than 1 sec-ond on it, a bigger tooltip is displayed, giving more informations (loss, reflectance, slope etc.).

NOTEFor PMD traces, you can position only one cursor (A).

NOTEYou cannot make a cursor selection with the PMD traces.



Trace information Once the A and B cursors are positioned on the trace, their respective positon and the difference between the two locations are displayed at the bottom of the trace.

NOTEThe cursors data are different according to the type of trace ope-ned.

Chapter 5 Analyzing OTDR TracesDefining Calculation Parameters

Defining Calculation ParametersBefore you make measurements you can define specific parameters you want to use, depending on the device used to acquire the trace.

Defining parameters

1 Select Calculation parameters … from the Calculation menu. The General parameters box is displayed:

2 Enter the required values or left click on the Default button to select the default values.

3 Click on the OK button to accept the displayed values and return to the trace display.

Fig. 28 Calculation parameters

NOTE

For reflectances you have to select one of the proposed value.

For splices you can either select a defined value or enter a value in the corresponding field.

For slopes, masks and ghosts you have to enter the required value in the corresponding fields


Chapter 5 Analyzing OTDR TracesAutomatic Event Detection and measurements

Event detection criteria

The detection of an event depends on the selected attenuation and reflectance threshold of the event. The event will be displayed if one of these values is above a threshold. Both results for an event will be dis-played if both can be calculated.

The event reflectance is always measured unless all the elements of the event cannot be measured, e.g. peak saturation or an event lost in noise. In such cases instead of giving the exact calculated reflectance value e.g. -30 dB, the display shows >-30dB to indicate that the reflec-tance is worse than -30 dB.

It is also possible to detect two events that are very close together, even though all the elements of each event cannot precisely be mea-sured.

Automatic Event Detection and measurementsYou can quickly locate all the events detected on the trace using auto-matic measurements as an OTDR will do it.

An automatic measurement detects all the events on the trace, dis-plays the measured value for each event, and generates an event result table.

To start an automatic measurement of a displayed trace define the specific calculation parameters you want to use for the measurement and press the button or select Automatic measurement from the Calculation menu or use the Shift + A keys.

The trace is displayed with all the detected events and the measure results associated.

– A marker is automatically set on each detected event.

NOTEThe values followed by H-M are only valid for Helios, the MTS and the RTU.


Chapter 5 Analyzing OTDR TracesUsing Markers

Using MarkersYou can position markers on the trace to indicate the exact position of detected faults so that you can quickly locate the same positions after repair or measurement using different calculation parameters.

Markers mode To position or modify the markers you must be in markers mode. To access this mode, click on the button in the Tools bar or select the Markers mode option in the Markers menu.

4 Right click on the trace and select Paste marker selection, or Paste and invert marker selection to copy the markers on the trace without or with inversion.

Manual measurements

Measuring the Slope of the Trace

You can easily measure the slope or linear attenuation of a section of the trace contained between cursors A and B.

To measure the slope or loss:

1 Position the cursors A and B in order to contain the section of the trace you want to measure (See “Cursors” page 47).

2 Press the button or select Slope from the Calculation menu.Red brackets display the origin and end of the section. The linear attenuation calculated is displayed between the markers in dB/km.

You can make as many slope measurements on the trace as you require as long as the sections do not overlap. If the slope measure-ment section overlaps another section previously defined and mea-sured, the new measurement replaces the previous measurement. Any other measurements calculated from this slope measurement are also deleted (refer to “Measuring Discontinuity on the Trace”).

NOTEIf you have not positioned the cursors before starting a slope measurement, the following alert message is displayed: «Impossible slope measurement. You should position two cursors.»



Measuring Discontinuity on

the Trace

You can measure the discontinuity (splice ...) between two sections of the trace where you have previously made slope measurements:

1 Make slope measurements on two sections of the trace (refer to “Measuring the Slope of the Trace” page 69).

2 Position cursor A between the two slope measurements at the right position on the event.

3 Press the button or select Splice from the Calculation menu.The result of the measurement is shown on the display with a blue marker indicating the exact measurement location on the trace.

The splice measurement values then remain associated with the trace even if the display is modified (Zoom function, etc.). To erase the splice measurement values you must use the Delete results command (refer to “Deleting all the markers and the results” page 64) or make a new measurement.

Fig. 32 Manual measurement results

Result of splice measurementResult of slope measurement

Result of reflectance



Measuring Reflectance on the

Trace

You can measure the reflectance of a Fresnel for a reflective event:

1 Position the cursor A at the base of the peak and the cursor B at the top of the peak of the required Fresnel (refer to “Automatic Event Detection and measurements” page 61).

2 Press the button or select Reflectance from the Calculation menu.The result is shown on the display with purple markers indicating the exact positions that correspond to the reflectance measure-ment.

The reflectance result then remains associated with the trace even if the display is modified (Zoom function, etc.…). To delete this result you can use the Delete results command (refer to “Deleting all the markers and the results” page 64) or make a new measurement.

Measuring the Optical Return

Loss

You can measure the Optical Return Loss (ORL) from a section of the fiber that is the amount of light reflected from the fiber. This value, in dB, is calculated as follows:

To measure the ORL: 1 Position the A & B cursors at the beginning and end of the section of the fiber you want to measure (refer to “Automatic Event Detec-tion and measurements” page 61).

NOTEBefore positioning a cursor, for greater precision, it is preferable to zoom in on the trace (refer to “Zoom-in” page 41).

NOTEIf you have not positioned the cursors before starting a reflectance measurement an alert message is displayed: «Impossible reflectance measurement. You should position two cursors».

ORL 10 Incident energyReflected energy----------------------------------------log=



To accurately position a cursor it is often easier to first zoom-in on the display (refer to “Measuring Reflectance on the Trace” page 71).

2 Press the button or select Optical Return Loss from the Calcu-lation menu.The section of the fiber measured is shown shaded green. A measurement result box in the top right-hand corner of the window shows:– the Reflectance Coefficient used (in dB)– the ORL value (in dB)– the Contribution to the reference point (in dB)

The ORL measurement result remains associated with the trace. It stays displayed just until a new measurement is carried out either from the button or by Optical Return Loss in the Calculation menu even if the display is modified (Zoom function, etc.…). To delete the ORL measurement result, press the button or select Optical Return Loss from the Calculation menu a second time.

NOTEIf you have not positioned the cursors before starting an ORL mea-surement the following alert message is displayed: «Impossible Opti-cal Return Loss measurement».

Fig. 33 ORL Measurement

ORL result



Measuring the Contribution

Once you have made an ORL measurement you can measure the contribution (in dB) to the overall ORL that a specific reflective event causes. This contribution is measured from the start of the ORL mea-surement.

Use the following procedure to measure the contribution caused by a specific event:

1 Make an ORL measurement on a section of the trace.

2 Position the cursors to indicate the start and end points of the event you want to measure the contribution for.The original position of the start of the ORL measurement is indi-cated with a solid green cursor. The section of the fiber where the event you are measuring is located is shown shaded green and the contribution value to the reference point in dB is displayed in the measurement result box.

The contribution measurement result is not associated to the trace. It stays displayed just until a new measurement is carried out.

Fig. 34 Contribution Measurement

Contribution of event to ORL measurement

Start of ORL



Defining a Mask To help you to detect faults on the fiber you can define a mask (or threshold) for a section of the trace that will indicate the first point of the trace that exceeds the selected threshold value.

In order to do this you must first specify the mask threshold value in dB and define the section of the trace where you want to apply the mask.

Use the following procedure to define the mask:

1 Select Calculation parameters … from the Calculation menu.

2 Enter the mask threshold in dB in the Mask field and press OK.

3 Position the cursor A and B at the extremities of the section of the trace where you want to apply the mask.

4 Select Mask from the Calculation menu to test the mask.

The area you defined is represented as a parallelogram:

– If no point of the trace exceeds the selected threshold, the paral-lelogram is green and a test status box is displayed in the top right hand corner of the display giving the selected mask value and an OK status message.

Fig. 35 Mask Test Result

Mask zone delimited by a parallelogram (Green = Good, Red = Bad)

Test status box


Chapter 5 Analyzing OTDR TracesDifferences between traces

– If the test fails, the parallelogram is red and the status box shows the distance from the start of the fiber to the first point that the trace exceeds the selected threshold and a Bad status message.

To erase the mask, select Mask from the Calculation menu.

Differences between tracesWhen two traces are simultaneously displayed (see "Displaying Multi traces (OTDR / WDM -OSA)" page 54), it is possible to obtain the trace corresponding to the difference, point by point, between the cur-rent trace and the overlaid trace.

To do this, select Difference between traces, in the Display menu. The difference is calculated by using the logarithmic values.

NOTEYou can only have the differences between traces acquired with the same type of OTDR, using the same pulse width, for fibers with the same refractive index. Unless the following alert message is dis-played: «Impossible difference calculation. The traces do not meet the conditions: same indices, same analyzers, same pulse width».

NOTEYou cannot make any calculations on the difference trace from the Calculation menu.

You cannot use the button Difference between traces... if more than 2 traces are opened.


Chapter 5 Analyzing OTDR TracesBoth End measurement

Both End measurementThe Both End measurement function allows the results of measure-ments made in both directions of the fiber (Origin to End or End to Ori-gin) to be used to obtain true splice and connector loss results.

Measurement Principles

The Both End measurement function uses the Multi-trace function (see “Displaying Multi traces (OTDR / WDM -OSA)” page 54).

The traces obtained form the two measurements (one in each direc-tion) are displayed with event markers. They are first displayed super-imposed, then one of them is inverted (left ↔ right), in order that the markers associated to the same events are on the same horizontal position.

The Both End measurement result table show the following loss types:

– The O → E and O ← E losses correspond to the measurements made in each direction.

– The third value corresponds to the average of the two previous values. It corresponds to the real value of the insertion loss of the event.

Execution of a Both End

measurement

Display of the two traces O → E and O ← E

Use the following procedure to make a both end measurement:

1 Open the trace file of the measurements made from one of the extremities of the fiber you want to measure (preferably O->E).

2 Use the Multi-traces >Add Trace command from the Display menu to select the trace file of the measurements made from the other end of the same fiber (preferably O<-E). See “Displaying Multi traces (OTDR / WDM -OSA)” page 54.

3 If necessary choose the type of inversion for the O<-E trace, in the Display > Preferences menu (see “Defining Calculation Parame-ters” page 60).


Chapter 5 Analyzing OTDR TracesBoth End measurement

4 If necessary select the launch cables in the Edit trace box called by the File > Edit trace information ... > Cable menu (see “Trace infor-mation” page 49).

5 Select the Both end measurement command from the Display menu to enable measurements from both ends.

The O → E and O ← E traces are automatically aligned when the measurement is started or when a launch cable is inserted. If necessary, shift the traces to align the corresponding events (see “Trace Shift (OTDR / WDM-OSA)” page 44).On the second trace the events are located by a vertical line. These line are markers: if they are not displayed, click on . On the active trace, if necessary: - move the markers to align them with the corresponding line of the second trace. - add new markers if they are missing on the active trace and present on the other trace.

6 Swap the traces using the swap radio button of the trace parame-ters window to select the second trace as the active trace.

7 Make on this trace the required adjustments and measurement as described previously.

The status bar, at the bottom of the trace, gives the values of the cursors A and B.


Defining Calculation ParametersBefore you make measurements you can define the following specific parameters:

– alarm threshold on the Power level (in dBm).– alarm thresholds for Statistics on Delta Signal/Noise ratio, Delta

Power level and Delta frequency.– alarm threshold on the Power level for trace comparison.– the OSNR measurement parameters:

Cursors Values

Cursor A - Frequency or wavelength (according to the unit) of the cursor A- Power level of the cursor A (dBm)

Cursor B - Frequency or wavelength (according to the unit) of the cursor B- Power level of the cursor B (dBm)

Cursor B - A - Difference (of frequency or of wavelength) between the cursors A and B.- Difference of power level between the cur-sors A and B.

NOTEThe wavelength difference result is negative if the cursor A is posi-tioned after cursor B.


Chapter 6 Analyzing WDM / OSA tracesDefining Calculation Parameters

Noise measurement distance, that is to say the difference between the frequency corresponding to the highest point of the channel and the frequency corresponding to the reference point for the noise: 25 / 50 /100 GHz (about 0,2/ 0,4/ 0,8 nm at 1550 nm). Noise measurement method: side of the peak where the reference point has been taken for the noise: to the right or to the left. For the method "Left+Right", it is the average value calculated from the levels obtained to the right and the left that is used.

– threshold for detecting channels on the OSA-155/160/200.– delta wavelength and delta level for importation on the OSA-155

To define these parameters select Calculation parameters … from the Calculation menu. The Calculation parameters box is displayed.

1 Check the parameters on which you wish to place an alarm threshold and enter the value of this threshold. A warning appears in the results table when these thresholds have been exceeded (see “Exceeding the alarm thresholds” page 95).

2 Select the distance of noise measurement (25, 50 or 100 GHz) and the noise measurement method (Left, Right, or Left+Right).

3 In the case of a spectrum acquired on an Acterna OSA-155, OSA-160 or OSA-200 enter the channel detection threshold.

Chapter 6 Analyzing WDM / OSA tracesCalculations carried out on the spectrum

Calculations carried out on the spectrum

MTSe Série 5000 traces

The following parameters are calculated from the spectrum resulting from the MTS 5x:

– the tilt gain and gain slope for the channels as a whole or between the cursors A and B if they are positioned.

– the total power between the cursors A and B.– the signal/noise ratio.

These results are displayed on the trace and in the results table.

To display a result on a trace, select it in the Display menu (Composite Power, Total Power, Tilt and Gain Slope).

Total power calculation

Tilt gain and gain slope calculation

OSA-155, OSA-160, OSA-200 traces

There are no calculations carried out on these traces, but when they are opened a search is made for the channels exceeding the chosen threshold.

NOTEIf the display of a result parameter is not selected in the Display menu, this parameter cannot be calculated. It is in grey in the Calcu-lation menu. This is to avoid erasing results that have not been reg-istered.


Chapter 6 Analyzing WDM / OSA tracesResults Table

Results TableWhenever you make a measurement a results table is generated con-taining the results of each channel detected.

To display this table, click on the button or select Results Table from the Display menu.

It is possible to choose the channels to be displayed in the table, sort the displayed data, display relative results with respect to a selected channel, display the statistics carried out (if the trace is obtained by multiple acquisitions).

Table contents without statistics

In the absence of statistics the parameters given for each channel are as follows:

1 Channel number (the number of detected channels is given in the first column header).

2 Frequency or wavelength (Lambda) of the channel according to the chosen unit.

3 Spacing between the channels.

4 Power level of the channel in dBm.

5 Noise level in dBm.

6 Signal/Noise ratio for the channel in dB.

7 Channel power / Composite power ratio (P/Pcomp) in %.

Fig. 43 Results table (without statistics) with an alarm



The contents of the last five columns of the table will be different if a display of the statistics is requested. They will indicate the current value, average value, max. value, min. value, and standard deviation of the parameter for which the statistics have been calculated (fre-quency or wavelength, level or signal/noise ratio).

Choice of channels

displayed in the table

In the Results menu, choose the channels for which you wish to see the results displayed in the table:

– All channels– Selection of channels between A and B cursors– Selection of channels in the user-defined grid (see “Grid (OTDR /

WDM)” page 41)

Results sorting By default, the results are classified by channel number in ascending order.

To modify the way in which sorting is carried out, select Results sorting in the Results menu, then choose the desired sorting criterion:

– Channel number– Frequency / Lambda– Level– SNR

Display of relative results

The table usually gives the results in absolute values. To obtain these results as relative values, that is with respect to the reference channel, do the following:

– In the Results menu, choose Channel related result ... : a dialog box enables you to choose this channel among those displayed in the table.

Link between the trace and the table

If you click on a channel in the table, it is highlighted in blue, and on the trace the active cursor (A or B) moves to the channel correspond-ing to this table of results.



Successive addressing of

channels according to the

sort method

On the trace and in the table, it is possible to make the cursor pass successively from one channel to another one according to the selected sort order. To do this:

– choose the cursor A or B for use on the trace.– click the key (or choose Peak search in the Calculation menu)

to go to the max. amplitude channel.– click either the or keys (or choose Next channel or

Previous channel in the Calculation menu) to make the cursor jump back to the previous channel or on to the following channel.

Table contents with statistics

The Statistics menu allows you to select the statistic results:

– on Frequency (or wavelength), – on Level, – on Signal Noise Ratio– on frequency and level (Mixed statistics)

According to the selected statistic, the table displays for each channel:

(SNR Min) and max. signal/noise ratio (SNR Max)– the standard deviation on the signal/noise ratio (Sdev SNR)– the total power/composite power ratio in % (P/Pcomp)


Chapter 6 Analyzing WDM / OSA tracesExceeding the alarm thresholds

Exceeding the alarm thresholdsAn alarm indicator appears in the table if the results exceed the alarm thresholds chosen in the Calculation > Calculation parameters... menu:

Comparing tracesOnce you have displayed a trace you can display a second trace in the same window. This is very useful for comparing the results of acquisi-tions before and after a repair or to detect changes occurred between acquisitions. You can also generate a new trace of the differences between an active trace and a reference trace.

Opening an overlay trace

To set another overlay trace, use the multi-traces display command (see “Displaying Multi traces (OTDR / WDM -OSA)” page 54).

Once 2 traces are displayed, click on the radio button of the trace to activate.

Trace resulting from difference between traces

When two traces are simultaneously displayed, it is possible to obtain the trace corresponding to the difference, point by point, between the current trace and the overlaid trace.

To do this, select Difference between traces, in the Display menu.

The difference is calculated by using the logarithmic values.

General indicator of a threshold exceeded on the channel (in the first column).

Indicator of a threshold exceeded regarding Delta Level sta-tistics.

Indicator of a threshold exceeded regarding Delta Frequency statistics.

Indicator of a threshold exceeded regarding Delta SNR sta-tistics.


Chapter 6 Analyzing WDM / OSA tracesComparing traces

NOTEYou can only have the differences between traces acquired with the same type of instrument, using the same pulse width, for fibers with the same refractive index. Unless the following alert message is dis-played: “Impossible difference calculation. The traces do not meet the conditions: same indices, same analyzers, same pulse width.”

NOTEYou cannot make any calculations on the difference trace from the Calculation menu.

NOTEYou cannot use the option Difference between traces... if more than 2 traces are opened.

Chapter 12 Measurement Report

12
FiberCable provides a powerful report generation function to ensure the efficient analysis of potential problems for cables.
A cable report is carried out using OTDR, PMD and/or CD measure-ments made on the fibers of the cable by a JDSU MTSe fitted out with an OTDR, PMD and/or CD module.

The report is generated in an ASCII tabulation delimited format, compatible with the majority of Spreadsheet programs on the market (Microsoft Exce, Lotus 123, ….).


– “Measurement Report Methodology” page 134– “Measurement Report pProcess” page 135– “Selecting traces” page 136– “Selecting parameters” page 147– “Previewing the report” page 156– “Generating the measurement report” page 157– “Post Processing the measurement report” page 158


Chapter 12 Measurement ReportMeasurement Report Methodology

Measurement Report MethodologyUsing FiberCable to generate measurement reports for fiber optic cables requires a specific test methodology:

1- Measurements in the field using a JDSU MTSe

The first step consists in doing measurements for each of the fibers of the cable for which you want to generate a report, at the different wavelength (in order to detect fiber bending effects). It can be OTDR measurements in both directions, PMD measurements and Chromatic Dispersion measurements.

The acquired traces are stored on the measurement device.

2- Report generation and post processing in the office

All the trace files must be transferred on the hard disk of the office computer equipped with FiberCable and a spreadsheet program such as Microsoft Excel.

– FiberCable is used to generate the report for the cable. – This report can be post processed using the spreadsheet program

before printing. – If Microsoft Excel is available, the macro delivered with FiberCable

can setup, format and print the report.

Requisites In order to use the FiberCable Measurement Report function you must first have certain specific measurement data available on the computer where FiberCable is installed:

– In distinct directories, sets of result files corresponding to OTDR traces (measurements in both directions for all the fibers of the cable), PMD traces, CD traces.

– The OTDR measurement conditions (instrument type, wavelength and pulsewidth) and the deviation thresholds on distance and attenuation.

– The list of fibers of the cable.– The fiber to be used as a standard reference for the other fibers in

the cable.– The required alarm thresholds to be used for the report.


Chapter 12 Measurement ReportMeasurement Report pProcess

Measurement Report pProcessThe successive steps required to generate a report are the followings:

1 Move the files from the MTSe to the PC via a media available (Ethernet, USB, CD etc.).

2 Select the traces to include in the report (OTDR, PMD and/or CD) after selection of the corresponding tab: see “Selecting traces” page 136.

3 Select the measurements parameters: according to the measure-ment selected (OTDR, PMD or CD), the menu Report or the button

will give access to the OTDR parameters, PMD parameters or CD parameters option (see “OTDR parameters” page 149, “PMD parameters” page 154, “CD parameters” page 155)

4 Preview the report under the Preview tab: see “Previewing the report” page 156.

5 Generate the report using the button or the Menu Report > Generate a measurement report. The report has then a text format.

6 To process this report using the Excel spreadsheet program, click on the button or select the Report > Execute the command: FiberCableMacro.xls ... See “Post Processing the measurement report” page 158.

Status of the fiber as it is in the selection list of the report. (refreshed at each action).



Measurement with middle point enables to measure a long fiber even if the range of the OTDR is not sufficient. Four acquisitions are carried out: one acquisition in both directions from the middle point of the fiber, then the fiber being closed, an acquisition from both extremities of the fiber. The result is four traces for one fiber.

On the display, in order to get the complete OTDR traces, the useless parts of traces 3 and 4 are cut out and:

– the trace 2 is positioned after the trace 3 to restore the O -> E trace.

– the trace 1 is positioned after the trace 4 to restore the E -> O trace.

If one of the traces is not displayed (trace 1 for ex.), the associated trace 4 is not cut but entirely displayed.

Measurement setup Select the Measurement setup tab:

1 Select the number of launch cable (0 to 3) at the start and at the end of the fiber under test by clicking on the corresponding radio buttons.

2 Select the type of measurement:– Traditional: for one fiber, one measurement in both directions,

therefore two trace files. – Loop measurement: two fibers are looped at one extremity, while

the acquisition is carried out at the other end. The result is two trace files for the two fibers. The loop parameters are defined under the Loop tab (see below).

– Measurement with Middle point: For the very long links, this type of measurement enables the artificial increase of the range (up to double). This means that for one fiber, four acquisitions can be carried out: one acquisition in both directions from the middle point of the fiber, then, after closing the fiber at the middle point, an acquisition from both extremities of the fiber. The result is four trace files for one fiber. The middle parameters are defined under the Middle point tab (see “Middle point” page 152).



3 If you do not wish to include in the report certain results linked to fiber launch cables, then activate the appropriate check box.

The Default button enables the automatic selection of: one launch cable at the start, one launch cable at the end, a classical measure-ment, removal of launch cable values.

Loop Under the Loop tab, define the loop configuration and how the acqui-sition is performed.

Recommended only for G.652 in the 1310 nm region– Sellmeier 5-term: A+Bλ2+Cλ-2+Dλ4+Eλ-4.

Recommended for all the other cases, even in non homoge-neous fiber links.

Reference wavelength

You can also change the wavelength taken as reference for delay calculation: other wavelength delays are subtracted from this refer-ence delay.

Calculation parameters

You can select the following parameters:

– dispersion results normalized to 1 km (dividing them by the fiber length expressed in km)

– minimum and maximum wavelengths displayed on the trace and in the table (from 1255.0 to 1650.0).

– the number of results listed in the table (1 to 400).– the wavelength increment between two successive results in the

table (from 0.1 nm).


Chapter 12 Measurement ReportPreviewing the report

Click on the OK button to enter the displayed values and go back to the trace display.

Previewing the reportBefore generating your report you can preview the traces to ensure that the correct data will be generated. There are two methods of previewing the files:

– either preview all the marked fibers directly.– or (for OTDR measurement only) preview the marked fibers on a

step by step basis. In this case, pressing the Next button allows to display the successive traces for each selected fiber and, if neces-sary, to modify them.

The data is displayed in the final report format with tabs giving the following data groups:

– General Information– Loss (dB)– Slopes (dB/km)– Reflectance (dB)– Spans (m)– OTDR Alarms (display the out of range values)– PMD– CD

Previewing bookmarked fibers

Click on the Preview tab button to visualize what will be stored in the spreadsheet file of the measurement report.

NOTEYou can directly open the traces of a fiber by a double-click on the corresponding line of the table.

Previewing bookmarked fibers

(step by step)

Use the following procedure to preview the marked files step by step:

1 Select the menu Report > Preview the fibers bookmarked (step by step).

The traces of the first fiber selected in the selection list displays.

OTDR traces for measurements made from both ends are displayed in the same window. The O <− E trace is inverted in X and/or Y so that the events correspond on both traces.

2 Make any modifications you require and click on the Next button to display the traces of the next fiber selected in the selection list.

3 Repeat the above step for each of the fibers marked in the selec-tion list.The Preview window allows you to visualize what will be stored in the spreadsheet file of the measurement report.

4 Press the OK button to close the Preview window and return to the Configure a measurement report window. You can also return to the Configure a measurement window without closing the preview window by clicking anywhere in the Configure a measurement window. To return to the Preview window click anywhere on it.

Generating the measurement reportOnce you have selected all the fibers you want to include in your measurement report and are satisfied with the previewed result you can generate the measurement report.

NOTEThe Previous button allows you to return to the previous fiber. The Stop button stops the preview and returns to the Configure a measurement report dialog box. The Execute button stops the step by step previewing. The preview continues normally.

NOTEGenerating the report is always possible even if the preview window shows errors.


Chapter 12 Measurement ReportPost Processing the measurement report

The Report generation function provides two methods of generating the data:

– either to generate the data for all the fibers directly – or, in step by step mode, open the successive files before saving

the data. In this case, the traces for each of the fibers selected are displayed one after another (using the Next button) to make any necessary modifications before saving the data in the selected spreadsheet file.

Generating the report Use the following procedure to generate the measurement report:

1 Select the menu Report > Generate a measurement report. The Spreadsheet File text box displays.

2 Select the directory where you want to store the generated spreadsheet file.

3 Enter its file name.

4 Select its type:.txt or *.*

5 Click on the Save button.

The measurement report is generated and stored in the spreadsheet file in ASCII tab delimited format.

Generating the report (step by step)

– Use the same procedure as detailed in the previous section but select the menu Report > Generate a measurement report (step by step).

– You can display the traces for each fiber sequentially to make any modifications. Then, the measurement report is generated and stored in the spreadsheet file.

Post Processing the measurement reportAfter you have successfully generated your measurement report you can open the spreadsheet file using a spreadsheet program such as Microsoft Excel to carry out any post processing you require.

You must first, if necessary, convert the file in an Excel format.



To help you do the conversion as efficiently as possible a special Excel macro file (FiberCableMacro.xls) is delivered with FiberCable, in the FiberCable directory. This file is used to select the user language and the required number of decimal digits, and to setup the pages for printing.

Using the Excel FiberCable Macro

1 Open the macro:– either, from Windows Explorer, by double-clicking on the Fiber-

CableMacro.xls file located in the FiberCable directory. – either, from the Configure measurement report window of Fiber-

Cable, by clicking on the button or in selecting the menu, Report > Execute command: FiberCableMacro.xls ...

The Excel application starts.

2 A macro warning message may appear. In this case select Acti-vate the macros.

3 A second warning message may appear. In this case select OK. The FiberCable box opens:

4 Click on the Configuration button.

NOTETo use this macro a printer must be installed.

5 Under the Configuration tab you can setup the report – the Language (for the user language see “Processing the report

in a user defined language” page 162).– the Paper size (A4, A5, etc.)– the Title of the report– the Logo filename: you can load most of the format accepted by

ExcelTM,– the Number of fibers per page: 1 to 48,– the Number of digits in the results: 1 to 3,– the display of a preview before printing

– the use of the Compact format

6 Under the Results tab, notch the results (OTDR, PMD, CD) to insert in the report:

For OTDR measurements select:– the wavelengths inserted in the report. If only one wavelength

is selected, the comparison is automatically removed from the report.

– It is not possible to select monomode and multimode wave-lengths simultaneously. Thus if a monomode wavelength is selected, the multimode values are not available and vice versa.

– the table of results to print: connector & splice, reflectance, slope, total link loss, out of range values, bi-lambda compari-sons (the macro can deal with more than two wavelengths, so you must select both wavelengths required for the comparison)

– Insertion loss and ORL table– import results coming from the JDSU OFI 2000 tester, via the

Fiber Budget software. Then, at the start of the macro, a window requests to indicate the directory where the OFI results are stored. This function is only possible if one of the boxes Insertion loss table and ORL table is notched.

NOTE

Total link loss table cannot be selected if the Compact format has been selected (under the tab Configuration of this box)



7 Once the configuration is finished, click on the OK button. The FiberCable box appears again: you must choose between generating the report or printing it.

Opening the FiberCable box

If this FiberCable box is not opened you can display it using one of the two following methods:

1 Click on the button.

2 Select the menu Tools > Macro > Macros ... The Macro dialog box displays: select the Auto_open macro and click the Execute button.

Report format Standard Format

In the standard format, the report includes the following informations:

1 the title

2 the table of contents

3 general information about the link, the cable and the measure-ments

4 a length table of each link section

5 bi-directionnal splice loss tables for each wavelength

6 section loss tables for each wavelength

7 total link loss tables for each wavelength

8 insertion loss tables for each wavelength

9 ORL tables for each wavelength

10 a table giving the results of the comparison between the two selected wavelength.

11 a table of PMD results

12 a table of CD results

13 a table of Out of range OTDR results (for the selected wave-length), PMD and CD results.

Compact Format

In the compact format:



– length, bi-directionnal splice loss, loss difference (between the two selected wavelengths) and total link loss values, for every wave-length, are put together in the same table.

– for each other parameter (slope, insertion loss, ORL, Out of range) there is only one table including results at every selected wavelength.

Report generation 1 Select the option 1: FiberCable file format.The Open file dialog box is displayed.

2 Select the report file and click Open. The macro formats the report then you are prompted to enter the file name for the report.

3 Enter this filename and click OK. The file is generated and you can analyze it before printing it.

Report printing 1 Select the option “2: Print preview formatted file” (or print formatted file) depending on the configuration selected.The Open file dialog box is displayed.

2 Select the report file and click Open. The macro formats the printing then the report is previewed.

3 Click on the Print tab to print it.

Processing the report in a user

defined language

When the FiberCableMacro.xls has been opened, the button and the FiberCable box are on the screen.

To translate the report text and the menus in your own language, if it is not one of those available:

– Close the FiberCable box.– Expand the button to display the worksheets.– Click on the User worksheet.

NOTEThe process speed is directly linked to the printer driver.
