PCT No. PCT/GB86/00741 Sec. 371 Date Jul. 27, 1987 Sec. 102(e) Date Jul. 27, 1987 PCT Filed Dec. 5, 1986 PCT Pub. No. WO87/03761 PCT Pub. Date Jun. 18, 1987.A method of operating a multiple-access network. The network has a number of communication stations having receiving and transmitting portions (1, 2: 3, 4: 5, 6). The stations are physically coupled together by optical waveguides and arranged such that each transmitting portion (1, 3, 5) can transmit signals to one or more receiving portions (2, 4, 6) but cannot transmit signals to the receiving portion of the same station. One method comprises enabling two stations to communicate with each other by transmitting information simultaneously in the same channel. Another method comprises enabling two stations to communicate with each other by causing the transmitting portion of one station to transmit an interfering signal in the same channel as the information transmitted by the transmitting portion of the other station, the interfering signal being such that at other receiving portions the information and interfering signals are received together.
