LED indication during optical link failure
If one fiber in the optical fibre pair fails, all cummunication with will be lost and the FL R
LED’s will turn on. The ODW-710-F1 that is still sensing optical power will indicate this
by flashing the CH1 LED.
If both fibers in the optical fibre pair fails, all cummunication with will be lost, the CH1
LED’s will turn off and the FL R LED’s will turn on.
