Abstract

The optical regenerative circuit comprises: branching circuit for supplying a received optical data signal to two branch circuits; optical clock generator circuit for generating an optical clock signal from a first optical data signal, the first optical data signal being the optical data signal supplied to a first branch circuit of the two branch circuits; optical discriminating circuit for discriminating in an optical form a logic level of a second optical data signal in synchronization with the optical clock signal produced by the optical clock generator circuit, the second optical data signal being the optical data signal supplied to a second branch circuit of the two branch circuits; and variable-delay circuit for adjusting timings at which the second optical data signal and the optical clock signal are received by the optical discriminating circuit, by delaying a predetermined one of the first optical data signal, the second optical data signal and the optical clock signal so that the timings are synchronized with each other.
