Abstract

A network monitoring module for deployment in a branched optical network at a split location where the network splits into a plurality of branches, the network monitoring module is disclosed, comprising an array of transmitters for generating optical test signals, an output of each transmitter in the array being optically connected to a respective branch, a detector for receiving a remotely generated optical trigger signal which identifies a particular one of the transmitters, and a CMOS circuit for selectively triggering the transmitter identified in the optical trigger signal to transmit an optical test signal into the branch connected to that transmitter.
