APPARATUS AND METHOD TO IMPROVE OPTICAL REACH IN BIDIRECTIONAL OPTICAL TRANSMISSION SYSTEMS EMPLOYING SINGLE-LASER COHERENT TRANSCEIVERS

Abstract:

Optical networks, transponders and single-laser coherent transceiver are described. The single-laser coherent transceiver includes a wavelength source, a transmitter and a receiver. The wavelength source is tuned to supply a first optical signal having a first wavelength. The transmitter receives the first optical signal and encodes client data into the first optical signal to generate a second optical signal. The receiver receives the first optical signal from the wavelength source and a fraction of the second optical signal.
