OTDR Fiber Optic Test Results
OTDR Fiber Optic Test Results
(OP)
I have two sets of test results for our single mode fiber optic line, one done at 1310nm and one at 1550nm, I was under the impression that I should get a little higher losses at 1550nm but this was incorrect as the OTDR was showing much higher losses at 1310nm,
Can anyone explain?
Thanks
Jeff

1310 nm 0.4 dB/km
1550 nm 0.3 dB/km
Dispersion-Shifted fiber will have even lower loss at the 1550nm end.

If there is a big disparity between the losses at 1310 and 1550, it could indiacate a tight bend/pinch point.
