FiberAlert (FA)
When Auto Negotiation is not supported or selected, then FiberAlert minimizes the
problems associated with the loss of one strand of fiber. If a strand is unavailable, the
IMC Networks device at the receiver end notes the loss of link. The device will then
stop transmitting data and the link signal until signal or link pulse is received. The
result is that the link LED on BOTH sides of the fiber connection will go out indicating
a fault somewhere in the fiber loop. Using FiberAlert, a local site administrator is
notified of a fault and can quickly determine where a cable fault is located.
WARNING
Enable FiberAlert on one side of a media conversion only. Enabling it on both
sides would keep both transmitters off indefinitely.
