At start of OTDR test, OFL280 checks connection to fiber-under-test

(if Launch Quality Check enabled)

Alerts user when poor launch condition exists at OTDR connector Usually due to dirty, damaged, or mismatched (UPC APC) connectors

Check and clean connection before continuing OTDR test

Launch quality checked after live fiber check (to prevent service disruption)

Good launch condition eliminates follow-up visit to obtain useful results

Provides user opportunity to clean and recheck, or continue test anyway

Whats Unique when Testing a Live PON?


35/79


One subscriber may lose service while others remain in-service

Network continues to transmit 1310, 1490, and possibly 1550 nm signals

Check downstream PON power levels at out-of-service ONT:

OK: Power at 1490 & 1550 nm wavelengths within expected levels

Dim or Dark: Little or no 1490 and/or 1550 nm power due to upstream fault

Cannot test a live PON using a standard OTDR!

OTDR test at 1310, 1490, or 1550 nm will disrupt service to other customers! Downstream 1490 or 1550 nm signals interfere with normal OTDRs receiver

Test in-service PON using a Live PON OTDR which includes:

An OTDR laser at an out-of-band wavelength (e.g. 1625 nm)

A filtered detector to reject in-service wavelengths (e.g. 1490, 1550)

Live Fiber OTDR mode in OFL280


36/79


All OFL280 models detect live traffic and prevent OTDR

testing at 1310 and 1550 nm when live traffic is present

If live traffic not detected, testing proceeds as previously shown

If live traffic is detected, OTDR testing @ 1310/1550 is not allowed

The OFL280-103 supports testing of Live FTTx PONs

Includes ServiceSafe live fiber detection

Includes integrated PON Power Meter to detect and measure

downstream power levels at 1490 and 1550 nm

ServiceSafe prevents OTDR testing at 1310 or 1550 on live fiber

Ensures service is not disrupted on live FTTx PONs

Allows out-of-band OTDR test using 1625 nm laser on live fiber

Understanding Events


50/79


Non -reflective eventsmay be any of the following:

Fusion splices:

Typically < 0.2 dB; Many too good to even be seen; Similar values at alll

s Macro-bends:

Typically in splice closures & access cabinets, often at connector & splice locations

Indicated by higher loss at longer l(1550, 1625 nm) vs. shorter l(1310, 1490 nm)

Non-reflective breaks

Clean angle-polished connectors (APC)

PON Splitters:

High loss events (> 3 dB) in PONs only

Loss depends on split ratio

Reflectiv e eventsmay be any of the following:

Connectors:

Reflectance > -40 dB indicates need for inspection and cleaning Reflectance > -20 dB indicates glass/air interface due to: open connection (end),

dirty/damaged connector, connector not fully seated, or UPC-to-APC connection

Mechanical connector

Verify the Results folder was transferred successfully

Put a copy of the Results folder on a backup drive

(e.g. a USB memory stick)

At this point you can delete the Results folder from the

OFL folder in My Computer. This will erase the Results

jumpers after referencing.

You will need to add a

receive jumper to the

OPM port of each unit.

Reduce Test Time with Wave ID


73/79


Wave ID reduces test timeup to 80% and eliminates setup errors

Simultaneously measures loss at multiple wavelengths

OPM synchronizes to wavelength sent by OLS, eliminating user setup errors With OFL280, measure loss on two fibers at once! Network

Test Steps Without Wave ID Test Steps With Wave ID

Bring OLS and OPM together to store

references:1. Connect OLS to OPM.2. Set OLS to 1310 nm.3. Set OPM to 1310 nm.

4. Store reference.

5. Set OLS to 1550 nm.

6. Set OPM to 1550 nm.

7. Store reference.

Bring OLS and OPM together to store

references:1. Connect OLS to OPM2. Set OLS to Wave ID, 1310 / 1550 nm.3. OPM detects Wave ID (< 2 secs)

4. Store reference (stores refs at both l).

Bring OLS and OPM to opposite ends

of network under test & measure loss.1. Connect OLS and OPM to network.2. Set OLS to 1310 nm.

3. Tell OPM user to set OPM to 1310.

4. Wait for OPM user to meas loss @ 1310.

5. OPM user sets OPM to 1550 nm.

6. Tell OLS user to set OLS to 1550 nm.

7. Wait for OLS user to switch to 1550 nm.

8. Measure loss @ 1550 nm.

Bring OLS and OPM to opposite ends

of network under test & measure loss.1. Connect OLS and OPM to network.2. Set OLS to Wave ID, 1310 / 1550 nm.

3. OPM detects Wave ID, simultaneously

measures loss at both1310 & 1550 nm.

Greater loss at longer

wavelength (1550 or 1625)

indicates a macro-bend.

The OFL280 OLS & OPM can also


75/79


Send fiber-identifying tones (270, 330, 1k, 2k Hz)

Detect fiber-identifying tones (270, 330, 1k, 2k Hz)

Send CW (continuous wave)

CW is useful when working with power meters from other vendors.

Wave ID is recommended when using a Noyes powermeter (or another OFL280) to measure loss

Wave ID cuts loss test time in halfwhen testing 1310 & 1550,

since it tests both wavelengths simultaneously

Wave ID eliminates setup errors, since theres no need to

coordinate wavelength settings in Source and Power Meter locatedat opposite ends of the fiber-under-test
