Abstract:
1. An optical communications system, comprising: a MSAP (Multi-Service Access and Aggregation Platform); an optical transceiver mounted at the MSAP that communicates over an optical network to at least one optical network terminal (ONT); a first electronic module operatively connected to said optical transceiver and configured to control the optical transceiver and mounted at the MSAP separate from said optical transceiver; a redundant second electronic module supported within said MSAP and mounted separate from said optical transceiver; and a Mux/Demux module interconnecting and supporting said first and second electronic modules to form an integral unit and mounted at the MSAP separate from said optical transceiver, wherein said Mux/Demux module is configured to switch said second electronic module into communication with said optical transceiver upon failure of said first electronic module wherein said Mux/Demux module comprises a multiplexer/demultiplexer circuit and an input/output crossover switch connected to said multiplexer/demultiplexer circuit.
