ABSTRACT:
An optoelectronic device for use in an optical communication system is disclosed. The optoelectronic device, coupling to each other the ports of a plurality (e.g. two or three) of optical data transmission lines, comprises: pass-through optical fibers connecting to each other the ports of the optical data transmission lines; receiving optical fibers connecting such ports to the input of an optical-to-electrical transducer; transmitting optical fibers connecting the output of an electrical-to-optical transducer to the above ports; a pulse width fixing circuit, having an input and an output coupled to the output of the optical-to-electrical transducer and the input of the electrical-to-optical transducer, respectively, for regenerating and amplifying the signal and limiting the pulse width of the regenerated signal to a predetermined fixed length; and a pulse width normalizing circuit (second pulse width fixing circuit) to whose output the input of a terminal electronic data processing device is coupled to receive information from the optical signal transmitted through the optical data transmission lines. The output of the terminal data processing device is supplied to the electrical-to-optical transducer.
