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

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)

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

Refl: Reflectance of event in dB
More negative reflectance is better
Better reflectance: smaller trace spike
Loss: Loss of event in dB
Fiber dB/km: Loss per distance of fiber preceding event
Typically ~0.35 dB/km for 1310; ~0.2 dB/km for 1550.

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
Poor splice with air bubble

AFL COMPANY CONFIDENTIAL
Here is one way to ensure you always have a
backup copy of your OFL280 test results: Copy(do not Move) the Results folder to your PC
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
folder on your OFL280.
The OFL280 will regenerate a new, empty Results
folder the next time you save results.

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.

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
