Abstract
An optical regenerative-repeater system according to the present invention includes an optical branch device for branching an input optical signal, a photodiode for converting an optical signal to an electric signal, a timing circuit for generating timing signal, and an optical latch circuit for latching an optical signal. A branched optical signal supplied from the optical branch device is converted to an electric signal by the photodiode. The timing circuit supplies a timing signal to the optical latch circuit in accordance with the electric signal supplied from the photodiode.
