ABSTRACT:
This relates to a fiber optics communication link, wherein a single optical fiber carries data bi-directionally between two computers. The first computer is coupled by means of control logic to a first transmitter and a first receiver. The first transmitter and receiver are in turn coupled to a single optical fiber by means of a Y-coupler. A second computer is similarly coupled via control logic to a second transmitter and second receiver, which is in turn coupled to the single optical fiber by means of a second Y-coupler. To minimize problems due to reflections, each receiver is disabled when its corresponding transmitter is transmitting data.
