Link Fault Signaling (LFS)
Supports the creation of a redundant or secondary connection. This can be ideal for those mission critical or constant service applications such as fiber to the building (FTTB) or Fiber to the Curb (FTTC). The LFS LED provides immediate indication of when a cable has been severed or when some other cause of disruption in service has occurred. Simultaneously, data transmission will be switched to the redundant link resulting in "non-stop" connectivity.
