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.
Claims25
An apparatus, comprising:
- at least one optical time division demultiplexer capable of demultiplexing an original optical signal into demultiplexed component optical signals;
- and
- at least one optical filter capable of optically filtering one of the component optical signals, wherein said optical filter has a bandwidth that is wide with respect to a bandwidth of the component optical signals and narrow with respect to a bandwidth of the original optical signal.
A receiving terminal comprising:
- at least one optical time division demultiplexer capable of demultiplexing a received optical signal into demultiplexed component optical signals;
- a plurality of optical filters capable of optically filtering one of the component optical signals, wherein said optical filter has a bandwidth that is wide with respect to a bandwidth of the component optical signals and narrow with respect to a bandwidth of the received optical signal;
- and
- a plurality of receivers configured to process the filtered component optical signals to produce a data stream.
A method of receiving an optical signal, said method comprising:
- receiving an optical signal;
- time division demultiplexing the optical signal into component optical signals;
- and
- filtering the component optical signals using a filter bandwidth that is wide with respect to the component optical signals and narrow with respect to the received optical signal.
An optical communication system, comprising:
- a transmitting terminal capable of transmitting at least one optical signal;
- an optical channel capable of propagating the optical signal from the transmitting terminal;
- a receiving terminal capable of receiving the optical signal propagated by the optical channel, said receiving terminal comprising:
- at least one optical time division demultiplexer capable of demultiplexing the received optical signal into demultiplexed component optical signals;
- a plurality of optical filters capable of optically filtering one of the component optical signals, wherein said optical filter has a bandwidth that is wide with respect to a bandwidth of the component optical signals and narrow with respect to a bandwidth of the received optical signal;
- and
- a plurality of receivers configured to process the filtered component optical signals to produce a data stream.
