Pulsing FiberAlert
Pulsing FiberAlert minimizes the problems associated with the loss of one strand
of fiber. If a strand is unavailable, the device at the receiver end notes the loss of
link. The device will stop transmitting data and start sending link pulses. Until a
valid link is received, the fiber link LED will be OFF on the device on the receiver
side of the fiber strand with the fault while the fiber Link LED on the other unit
will blink. Pulsing FiberAlert notifies a local site administrator of a fault, allowing
quick determination of where a cable fault resides.
NOTE
Pulsing FiberAlert can be enabled on BOTH sides of a conversion.
