Part IV: Measures and principle

Generalities1

Available measures1.1Here below is the list of measures transferred from the instrument to CIM.

Measure unit Description accesslevel

Asymmetry Value of the global asymmetry of the different layers. user

Diameter [µm] Value of the outer diameter. user

Speedmmin

[m/min] Value of the production speed. user

Speed ms [m/s] Value of the production speed. user

Temp. [°C] Value of internal temperature of the instrument. Shouldnot exceed 55°.

supervisor

Vibration [Hz] Value of the vibration frequency of the measured object. user

X position [mm] Value of the X position for the measured object. user

Y position [mm] Value of the Y position for the measured object. user

Remark: A non-measured value is forced to zero, except for X & Y positions which are force to -5.00mm

Events1.2It is a particular phenomenon that is detected by the instrument. Events are detected in real time,dated (5ms accuracy) and located (fiber length). Each event is also characterized by its extremumvalue.

Here below is an example of high speed diameter fluctuation which exceeds the tolerances.

Real time scopes1.3Because the measurement frequency of the instrument is very high, it is impossible to transfer allmeasures in real time to the computer through RS232.The instrument stores the main measures continuously in internal buffers of 500 points each .This function is called Real Time Scope.

Those buffers can be watched through CIM. Only few buffers per seconds can be watched,because of communication constraints.

The sampling period of each buffer can be modified, depending on the time scale you want toanalyse.

Those tools are very useful for process analysis to qualify the stability, the regulation performance,and display some particular effects. The F.F.T. processing shows specific oscillations. Werecommend strongly to the process engineer to use those tools for understanding andimprovement of the manufacturing process.

Diameter2

Optical principle2.1Diameter measure is based on Diffraction principle.

CM5 user's manual

Part IV: Measures and principle

Version : 14.0.0

Diffraction scope2.2This scope shows 1 signal:

CCD diffraction axis 1: Light energy vs pixel. It shows the signal acquired by the CCD.

This scope is used for maintenance purpose to check the signal quality.

Results displayed in the scope:Diameter: the diameter measure corresponding to the displayed signal.Status: the alarm code corresponding to the displayed signal.Amplitude: the fringes amplitude. This value should be around 30 for 245µm fiber, otherwise theinstrument is not good conditions for measurement.

Real time diameter scope2.3This scope shows 1 signal:

Real time diameter diffraction: Diameter vs time. It shows real time diameter fluctuations.

This scope is interesting for process study and analysis. It can show high speed phenomenon,such as spinning or diameter oscillations.

The following parameter can be adjusted:Sampling period [ms]: Represents the duration between 2 storages inside the buffer. It isused to adapt the time scale. Minimum value: 2.500ms.

13Part IV: Measures and principle

Version : 14.0.0

Lump & Neck detection3

Principle3.1CM5 can detect Lump & Neck based on light energy high speed change.

Necessary bandwidth, sampling frequency:The analog bandwidth of the sensor (after amplification) is 800kHz (-3dB). This signal is digitallyconverted with a sampling frequency of 14.4MHz (one sample every 69.4ns) and averaging over 4samples, it corresponds to an effective frequency of 3.6MHz, so a fiber length of 11.1µm at 40m/s(2400m/min).A short lump of 100µm at 40m/s will be analysed with 9 samples.

Typical scope, Lump & Neck example:Here below, is a typical Lump & Neck image. All 5 axes are shown in our "last image real timescope".Axes are vertically offset with a distance of 1 mm between each axis. It explains the temporal shift(horizontal) between each detection on the following charts.

In case of high-speed diameter change, the system will detect and store all information then itgenerates:

A change of the digital output state. Refer to Digital I/O chapter.An event in CIM software.

The tolerances for Lump & Neck detection is adjustable. Refer to tolerances chapter for furtherinformation.

Limitations3.2Old technology: with 3 axes, there are 6 tangential points on the circumference, every 60°. Atthe intersection of the tangential rays (here below yellow and bleu areas), there are shadows. Theyellow areas represent 7.7% of the diameter, 19µm uncertainty for 250µm over 1/6 of thecircumference diameter. With this type of instrument it is erroneous to think it can accuratelydetermine the exact diameter fluctuation.

3 axes

CERSA technology: with 5 axes, there is 36° between tangential rays, (1/10 of thecircumference) with a maximum shadow of 2.6% of the diameter which is 6.43µm for 250µm.

5 axes

From 3 to 5 axes (2 more axes), we divide by 3 the shadow amplitude with a much better

coverage of the circumference of the fiber.

Internal defect detection4

The internal defect detection is based on the light energy diffused by the fiber. The system tracksin real time (800kHz bandwidth) the energy fluctuation.This system is dependant on all internal defects such as bubbles, delamination, particles, airline.The sensitivity of the detection depends on the defect size, length and position inside the fiber.

In case of defect detected, it generates:A change of the digital output state. Refer to Digital I/O chapter.An event in CIM software.

Coating asymmetry5

Asymmetry, principle and limitations5.1CM5 measure asymmetry based on Interferometry principle.

Here below are described different situations and the influence on the asymmetry measurement(limitations).

o Wet on dry process, instrument placed just before the second coating

injection: Asymmetry on single coating layer is a liable information. By comparinginline asymmetry measure and offline eccentricity (with external measurementinstrument), you can establish a proportional relationship between the asymmetryvalue and the eccentricity measurement in micron. This relationship is directlydependant on index values and coating temperature. It means that the CM5 placed onthe primary layer can give a consistent eccentricity measurement.

o Wet on wet process, CM5 placed just after the last UV block (before capstan). If

your process insures the perfect concentricity between both coating layers, ourinstrument will provide a liable coating to glass asymmetry measure. Due to thecomplexity of the profile (indexes, internal diameter, temperature), the asymmetrymeasure can't be correlated with an eccentricity measurement in micron.

16

CM5 user's manual

Part IV: Measures and principle

Version : 14.0.0

o In other situations, asymmetry on two coating layers is effective but not liable due to

potential exact compensation of opposite eccentricities between glass and coatingslayers.

Remarks: The asymmetry measure unit is arbitrary. It corresponds to a number of fringes.The target is to reduce the asymmetry close to zero by adjustment of the coating process.

Interferometry scope5.2This scope shows 1 signal:

CCD interferometry axis 1: Light energy vs pixel. It shows the signal acquired by the CCD.

This scope is used for maintenance purpose to check at the signal quality.

Results displayed in the scope:Asymmetry: the asymmetry measure corresponding to the displayed signal.Status: the alarm code corresponding to the displayed signal.Amplitude: the fringes amplitude. This value should be around 130 for 245µm fiber, otherwisethe instrument is not good conditions for measurement.

Colored coated fiber6In some optical fiber drawing process, colorization is made inline (pigment mixed with coating).In such a case, coated fiber is not transparent and already gets its final color.Color around coated fiber modify the transparency ratio for the light that goes through the fiber.It creates an attenuation for light energy that goes through the fiber compared to a transparentcoated fiber.In order to compensate this attenuation CM5 automatically auto-adapt some internal parameters.

Two Parameters are useful to control this auto-adaptation:Energy diffused transp. ratio: set the maximal admissible range to make auto-adaptation(example of value: 1 = transparent coated fiber; 3 = colored coated fiber with an opticaltransmission attenuation factor of 3 compared to a standard transparent coated fiber (forinstance: black color))

Energy diffused min[%]: (only for CERSA)

17Part IV: Measures and principle

Version : 14.0.0

Position and vibration7

Principle7.1Fiber position is measured by 2 position sensors: X and Y.Those sensors analyse the light diffused by the fiber and provide an accuracy of +/-0.1mm.The measurement range is limited to +/-2.0mm on both sensors.

The vibration frequency measurement comes from the spectrum analysis of the Y position signal(more sensitive than X). It can be measured only if oscillations are stable and large enough.

Vibration scope7.2This scope shows 2 signals:

F.F.T. of the X or Y position: Energy vs frequency. It shows the normalized Fast FourierTransform of the X or Y position signal..X or Y position signal: X or Y axis position vs time. It shows fiber position measured by the Xor Y position sensor.

This scope is interesting for vibration analysis. When the instrument is placed between the furnaceand the first coating die, it can display the natural fiber vibration which is an image of the drawingtension.

Results displayed in the scope:F.F.T. DC energy: represents the F.F.T. level of the DC part (Frequency = 0Hz)F.F.T. peak energy: represents the F.F.T. level of the main peak.Frequency [Hz]: the vibration frequency value of the detected F.F.T. peak.

The following parameters can be adjusted:

Remark about diffraction diameter offset:Thanks to the optical system and measurement principle, you should not modify the offset value(default value: 0). In case of you really need to correct the measure, you have to follow thisprocedure:1. Wait for the temperature stabilization for at least 5 minutes.2. Be sure of the cleanness of the optical system.3. You must have a standard glass fiber. The standard has to be very circular (non-circularity less

than 0.2µm) and must be measured by an external accurate offline measurement system.4. Clean perfectly this standard with IPA(IsoPropylic Alcohol).5. Place this standard (without touching the part which will be measured) in the center of the

instrument. Be sure that the standard position is around 0.0mm (+/- 0.2mm).

Mounting1You do not need any fine adjustable support. A single horizontal metal plate, 3 mm thick, with4x 4.20mm holes would be sufficient.You must reserve the possibility of a manual adjustment to adjust the position of the instrumenton the fiber axis.

Constraint of horizontality :The instrument must be perfectly placed horizontal (perpendicular to the fiber). Using the top whitecover as a reference, you must adjust the horizontality with accuracy of +/-0.25°.This constrains is absolutely necessary to have the instruments in good conditions for accuratemeasurements (Diameter, Lump&Neck, …).

CM5 must absolutely be placed just after the last UV bloc and before any pulley capstan orspinning system to not be disturbed by surface defects produced by the contact.You must protect the instrument against any liquid coating fall.

The internal temperature must be checked (55 degrees maximum) with CIM software during fiberdrawing, especially at the highest production speed.

Remark:Air supply is necessary to maintain the internal temperature and ensure the behavior ofelectronic devices.

Alignment2All measures are independent of the fibre position while the fibre stays within 1.5mm radius.

We recommend to keep the fiber within a 1.0mm circle radius.

Out of a 1.5mm circle radius, the measurement is not possible.

Safety rules1There is no particular protection constraint for users in the case of a normal operation of thedevices.

Laser source information:The laser is not directly visible if you keep mounted the mechanical protection and if you do notinsert into optical bench any optical reflective object.Class 1M laser device according to the classifications given by the "American NationalStandards Institute", document ANSI Z136.1-2007, page 1.

Optical system cleaning2The lenses cleaning should be performed regularly depending on the environment.In most of the cases, a simple dry air blowing action each month into the lenses protection issufficient.The user must remember that dust on the lenses degrades the device’s accuracy.

To clean the lenses, please follow this procedure:1. Unplug the power supply.2. Remove the top black cover (you must first remove the screw).3. Use dry air to eliminate the biggest particles.4. Use cotton or dry tissue with IPA (IsoPropylic Alcohol) and clean carefully each dirty lens.5. Check visually the surface of the lenses.6. Replace the cover and tight the screw.
