Abstract
A system for mitigating the effects of polarization hole burning in an optical communication system. The system includes an optical input signal comprising one or more traffic channels, a measurement module configured to check for the existence of ghost channels around the traffic channels, and a ghost channel generation module configured to generate a ghost channel around the traffic channels from amplified spontaneous emission noise of the optical input signal.
Claims16
A system for mitigating the effects of polarization hole burning in an optical communication system, comprising:
- an optical input signal comprising one or more traffic channel(s);
- a measurement module configured to check for the existence of ghost channels around the traffic channel(s);
- and
- a ghost channel generation module configured to generate a ghost channel around the traffic channel(s) from at least an amplified spontaneous emission noise of the optical input signal.
A method for mitigating the effects of polarization hole burning in an optical communication system, comprising:
- receiving an optical input signal at a first node of the optical communication system, the optical input signal comprising one or more traffic channel(s);
- checking for the existence of a ghost channel around the traffic channel(s);
- generating a ghost channel around the traffic channel(s) from at least an amplified spontaneous emission noise of the optical input signal;
- and
- forwarding the traffic channel(s) and the ghost channel to a second node of the optical communication system.
A method for mitigating the effects of polarization hole burning in an optical communication system, comprising:
- receiving an optical input signal at a first node of the optical communication system, the optical input signal comprising one or more traffic channel(s);
- forwarding the traffic channel(s) to a second node of the optical communication system;
- amplifying at least a spontaneous emission noise within a ghost channel;
- forwarding the traffic channel(s) and the ghost channel to a third node of the optical communication system;
- comparing an optical strength of the ghost channel to an optical strength of the traffic channel(s);
- if the optical strength of the ghost channel is substantially equal to the optical strength of the traffic channel(s), capping amplification of the ghost channel;
- and
- if the optical strength of the ghost channel is not substantially equal to the optical strength of the traffic channel(s), amplifying the ghost channel.
