System and method for mitigating dispersion slope in an optical communication system
First Claim
Patent Images
1. A method of receiving an optical signal, said method comprising:
- receiving an optical signal;
time division demultiplexing the optical signal into component optical signals using a time division demultiplexer; and
mitigating chromatic dispersion slope in said optical signal by;
determining a filter bandwidth in response to a clock frequency of the received optical signal and a clock frequency of the demultiplexed component optical signals, said filter bandwidth being greater than twice the clock frequency of the demultiplexed component optical signals and less than twice the clock frequency of the received optical signal; and
filtering the component optical signals in an optical filter using said filter bandwidth.

Abstract
A system and method for mitigating dispersion slope is capable of reducing the performance impact on an optical communication system caused by dispersion slope. The system and method receives an optical signal, demultiplexes the optical signal and optically filters the demultiplexed optical signals. The optical filters may have a bandwidth that is wide with respect to the demultiplexed optical signals and narrow with respect to the original optical signal.
