What Is FiberAlert? 

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 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 on one side of a media conversion only.  Enabling it on both 
sides would keep both transmitters off indefinitely. 

Using FiberAlert and LinkLoss 

Modules ship from the factory with troubleshooting features disabled.  Refer to the 
configuration instructions on pages 5-6 of this manual, or the help file to 
enable/disable this feature. The following chart provides an overview of the 
troubleshooting features, their functionality and the recommended settings for a pair 
of media converters in a typical central/main site to remote site application:
