ABSTRACT:
A downlink portion consists of a multiplexer for combining several signals. The combined signal is converted to an optical signal by a laser and transmitted over an optical line to a splitter. The split signals are each transmitted to a detector which converts the optical signals back into an electrical signal. The electrical signal is then filtered to provide the desired signal from the combined signal. The desired signal is then transmitted. The uplink portion consists of a plurality of receivers which receive signals from remote units. The received signals are multiplexed and converted to optical signals in a laser. The optical signals are transmitted over optical lines to a combiner which provides a single combined optical signal. The combined optical signal is then transmitted over optical lines to a detector which converts the optical signals to an electrical signal. The electrical signal is then demultiplexed into its constituent portions.
