ABSTRACT:
A data link is disclosed which utilizes differential communication between pairs of transmitting and receiving devices. In particular, one device of each pair is reserved for communicating a logic"O" and the other is reserved for communicating a logic "1". The pairs are grouped to form an array which is capable of providing simultaneous parallel communication, at relatively low bit rates, between two equipment components. The communication may be either unidirectional or bidirectional between the components. The ability to integrate the arrays of transmitting and/or receiving electronics and optics allows for improved reliability of the inventive system over a single fiber, high data rate, alternative.
