FIBERALERT AND FAR END FAULT
Modules ship from the factory with troubleshooting features disabled. Refer to
the Help file to enable/disable this feature.
FiberAlert (FA)
FiberAlert minimizes the problems associated with the loss of one strand of
fiber. If a strand is unavailable, the B+B SmartWorx device at the receiver end
notes the loss of link. The device will then stop transmitting data and the link
signal until a 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 at the remote side of a media conversion only. Enabling it on both sides would keep both transmitters
disabled indefinitely.
By default FA is disabled. When enabled if, a fault occurs on the fiber line,
affecting data in one direction, FA stops sending signal in the opposite
direction. FXLL will act on this lack of signal, propagating the loss of like to the
copper port when FXLL is enabled.
Far End Fault
By default, FEF is disabled. When enabled, and a fault occurs on the fiber line,
affecting data in one direction, an FEF signal will be sent in the opposite
direction, indicating the fault. FXLL will act on this signal propagating the loss
of link to the copper port when FXLL is enabled.
