ABSTRACT:
In a lightwave transmission system for transmitting a digital signal from a transmitter to a receiver through a lightwave guide, in order to enable to transmit a digital signal having a DC component, a constant light beam is switched over to one of two parallel lightwave conductors by an optical directional coupling switch in response to the digital signal so that the parallel light wave conductors form a balanced lightwave guide to transmit the digital information signal as balanced optical signals. Two photo sensors are disposed at output ends of the two lightwave conductors and sense the balanced optical signals transmitted through the lightwave conductors to produce balanced electric signals which are, in turn, compared at a comparator to reproduce the digital signal.
