Title: Method for supplying monitor and control signals to optical signal passing through optical transmitter, pump source, optical communication system and fiber raman amplifier
Inventor: GEHLOT NARAYAN L
IPC: H04B10/08
Filed: 2002-10-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide an arrangement which can monitor the performance of a fiber Raman amplifier without incurring penalties on transmitted data signals.  <P>SOLUTION: The arrangement for monitoring the performance of each pump source in a fiber Raman amplifier arrangement utilizes a set of unique 'signature' signals, each signature signal impressed on a different pump input signal. At a receiver, the signature signals are extracted from received amplified signal. If a particular signature signal is missing at the receiver, this is indicative of a failure of its associated pump source at a transmitter. If a particular signature signal is noticeable weaker than other received signature signals, this is indicative of a power loss in its associated pump source. Since each signature signal is chosen to be unique, the identity of each pump source can be easily ascertained.  <P>COPYRIGHT: (C)2003,JPO
