cables using an 850 nm optical light source and an 850 nm/dBm power
meter. If there is no damage to the fiber optic cables, and the problem
persists, please call Whirlwind Technical Support for assistance.

Once the laser link between the antennas is functioning, the fiber optic
link LED will turn on.

Fiber Optic Link Troubleshooting

If the fiber optic link LED on one modem is lit, but not on the remote
modem, and the fiber data lights are flickering, as shown in the graphic
on the below, it could be that:

!

The modem at Site 1 is transmitting a laser signal to the remote

site, but it is not receiving a laser signal from Site 2 that is good
enough to establish link (greater than -30 dBm).

!

The received optical power is higher than +2 dBm, which is

causing receiver saturation. (*Note: Refer to page 15 for a
definition and instructions on how to correct this problem.)

Site 1

Site 2

To fix this problem, one possible solution would be to make sure that
the remote site is using the correct Ethernet cable. Confirm that the
