ABSTRACT:
An active optical coupler for use in an optical data link communication system includes a multi channel coupler having a plurality of input channel fibers for receiving an original optical signal, an optical branch separating the original optical signal into a predetermined number of separated optical signals, and a plurality of output channel fibers for distributing the separated optical signals. An amplification circuit is connected to one of the output channel fibers which distributes the separated optical signal having a lowest power for amplifying this separated optical signal to produce an amplified optical signal. This amplified optical signal is supplied to any other of the input channels other than that which the original optical signal is input to and then distributed to the output channels again.
