SYSTEM AND METHOD OF COMPENSATING FOR SPECTRAL EXCURSION

摘要

An optical network comprises a plurality of optical network units and an optical line terminal having one or more transmitters and one or more receivers. Each of the one or more transmitters and each of the one or more receivers is configured to operate over a respective wavelength. Each of the optical network units has a respective laser that is optically coupled to a respective one of the one or more transmitters and a respective one of the one or more receivers. The optical line terminal is configured to monitor power levels of respective optical signal burst transmissions from each of the plurality of optical network units and to direct each optical network unit to wavelength bias its respective laser based on the monitored power levels to compensate for a respective wavelength shift experienced by the respective laser during burst transmissions.

1. An optical network comprising:
an optical line terminal having one or more transmitters configured to transmit optical signals and one or more receivers configured to receive optical signals, wherein each of the one or more transmitters and each of the one or more receivers is configured to operate over a respective wavelength; a plurality of optical network units, each of the optical network units having a respective laser that is optically coupled to a respective one of the one or more receivers in the optical line terminal; wherein the optical line terminal is configured to monitor power levels of respective optical signal burst transmissions from each of the plurality of optical network units and to direct each optical network unit to wavelength bias its respective laser in an direction away from the respective wavelength between optical signal bursts based on the monitored power levels to compensate for a respective wavelength shift experienced by the respective laser during burst transmissions.
