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.
Claims13
Apparatus for transmitting and receiving data, comprising:
- a. master means for generating a master timing signal timing at known intervals;
- b. first means connected to said master means for responding thereto by sending encoded data when said master timing signal is received;
- c. a second means for decoding received data;
- d. an optical fiber having a first end and a second end opposite to said first end thereof for transferring received data at said first end to said second end and at said second end to said first end;
- e. a third means for coupling said first end to said first and second means;
- f. a fourth means for decoding received data;
- g. a slave means responding to said fourth means decoding received data by generating a slave signal;
- h. a fifth means connected to said slave means for transmitting encoded data when said slave signal is received;
- and
- i. a sixth means for coupling said second end to said fourth and fifth means.
