Abstract

A single optical fibre 10 carries data bidirectionally between two computers. The first computer is coupled by means of control logic to a first transmitter T1 and a first receiver R1. The first transmitter and receiver are in turn coupled to the optical fibre by means of a Y-coupler 2, 4, 6. A second computer is similarly coupled via control logic to a second transmitter T2 and second receiver R2, which are in turn coupled to the fibre by means of a second Y-coupler 14, 16, 18. To minimize problems due to reflections, each receiver is disabled when its corresponding transmitter is transmitting data. Correct reception of each bit at the second computer is confirmed by retransmission back to the first computer. <IMAGE>
