Abstract
In a fiber optic communications system in which channel insertion and removal is carried out by a plurality of modular cascaded multiplexer and demultiplexer components, the respective common outputs and inputs of the multiplexer and demultiplexer components are connected to bi-directional or uni-directional combiners arranged to combine or separate groups of channels for transmission over a single fiber transmission cable. The combiners each include one or more optical circulators.
