ABSTRACT:
An optical signal monitoring system includes a bit rate information collecting unit and a monitoring unit. The bit rate information collecting unit gets bit rate information indicating a bit rate of an optical signal passing through an optical communication path. The monitoring unit extracts a monitoring optical signal from the optical communication path. When the bit rate information is not able to get, the monitoring optical signal is judged to be a noise. This system can make a sharp distinction between a broad optical signal whose bit rate is over 40 Gbit/sec and the ASE noise. Further, this system can correct optical signals dependently to those bit rates.
