Fault Description Cause of Failure Solution
OTDR will not turn on. The battery is dead. Charge the battery and observe the charging
indicator. If the red light is displayed, continue
charging.
OTDR cannot be charged normally. Ambient temperature not within acceptable
levels.
Replace charger. Try charging the OFL100 with the
USB port.
Check that the charger is working. Set range to greater than the length of the ber.
OTDR does not measure and display
test results.
OTDR parameters are not set correctly. Set range to greater than the length of the ber.
OTDR bulkhead is contaminated. Clean OTDR bulkhead and eld ber ferrule.
OTDR bulkhead is damaged. Send to Vista for bulkhead repair.
Optical output connector mismatch. Use correct ber size and connector to match
bulkhead.
The noise of test curve is excessive,
and the waveform is not smooth.
The eld ber is not connected properly to
the bulkhead.
Clean and reconnect the eld ber to the bulk-
head.
The pulse width setting is too small. Increase the test pulse width.
Averaging time is set too low. Increase the averaging time.
Events are saturated. The pulse width is too long. Decrease test pulse width.
The last connector is open and likely a flat
polished connector.
Terminate the last connector or place a Mandrel
wrap on the ber before the last connector.
After a reflective event there is a long
tail.
OTDR bulkhead is contaminated. Clean OTDR bulkhead and eld ber ferrule.
OTDR bulkhead is damaged. Send to Vista for bulkhead repair.
The reflection peak at the end of the
ber cannot be measured.
OTDR parameters are not set correctly. Set range to greater than the length of the ber.
The pulse width is too short. Increase the test pulse width.
False positive in curve analysis. Event threshold setting is too low. Increase the threshold analysis setting.
The ber length measured appears to
be not correct.
OTDR parameters are not set correctly. Set the range to capture all of the ber. Ser pulse
width so that the events are not saturated.
The index of refraction of the ber is not
correct.
Enter the index of refraction from the data sheet.
