TFR Functions
The TFR fiber-optic repeaters perform two functions: conversion between
electrical and optical signals, and repeating.
In the application diagrams below, RADring hubs located at distant sites are
interconnected by a fiber-optic segment, terminated by two TFR modules. A
simplified functional diagram of the TFR module and its fiber-optic segment
is presented in the diagram of this section.
The TFR module implemented as the RO module of the RADring receives
the main path ring signal, recovers its timing and then regenerates a clean
and jitter free retimed signal, by using a unique jitter attenuator circuit.
