ABSTRACT:
An apparatus is disclosed for transmitting binary-coded information over a fiber-optic link which provides a link monitor to indicate whether the fiber-optic link is intact and operating. The binary-coded information is translated into a pulse-coded signal which provides a positive pulse for a positive-going transition in the binary signal and a negative pulse for a negative-going transition in the binary signal. In addition, a refresh pulse of the same polarity as the preceding pulse is provided whenever there has been no pulse for a predetermined amount of time.
