Abstract (en)
[origin: WO8702205A1] An optical distribution system for 2-way communication from an exchange to a number of user stations (30). The user stations may comprise offices or homes and be arranged to receive bidirectional telecommunications signals, hi-fi stereo signals or other data. The system includes an exchange transmitter (2), exchange receiver (4) and an exchange coupler (10) for coupling the transmitter to an optical fiber line (14). Located remote from the exchange is a passive multi-port coupler (18) including optic fiber tails (16) extending to the user stations. Each user station includes a transmitter (32), receiver (34) and a coupler (36) for coupling the fiber tail (26) to the station transmitter and receiver (32, 34).
