CHROMATIC DISPERSION PRE-COMPENSATION OVER BI-DIRECTIONAL OPTICAL LINK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18449512 titled 'CHROMATIC DISPERSION PRE-COMPENSATION OVER BI-DIRECTIONAL OPTICAL LINK

Simplified Explanation

The patent application describes a method for optical communication between transceivers through an optical link for chromatic dispersion pre-compensation. The method involves generating and sending CD pre-compensated optical signals from a second transceiver to a first transceiver through the optical link. The first transceiver receives the signals and calculates the residual chromatic dispersion (RCD) values. It then calculates PCD filters using these values and uses them to generate and send CD pre-compensated optical signals back to the second transceiver, which provides tunable CD pre-compensation capability.

  • The method enables optical communication between transceivers through an optical link.
  • CD pre-compensated optical signals are generated and sent from a second transceiver to a first transceiver.
  • The first transceiver calculates the RCD values from the received signals.
  • PCD filters are calculated using the RCD values and used to generate CD pre-compensated optical signals.
  • The second transceiver provides tunable CD pre-compensation capability.

Potential Applications

This technology has potential applications in various fields, including:

  • Optical communication systems
  • Fiber optic networks
  • Data centers
  • Telecommunications industry

Problems Solved

The technology solves the following problems:

  • Chromatic dispersion in optical communication systems

Original Abstract Submitted

A method for optical communication between transceivers through an optical link for chromatic dispersion pre-compensation, includes generating and sending, by a second transceiver, a first CD pre-compensated optical signal and a second CD pre-compensated optical signal, to the first transceiver through the optical link. The method further includes receiving, by a first transceiver, the first and second CD pre-compensated optical signals, and calculating a first residual chromatic dispersion (RCD) value from the received first CD pre-compensated optical signal, and a second RCD value from the received second CD pre-compensated optical signal. The method further includes calculating, by the first transceiver, a third PCD filter using the first RCD value, and a fourth PCD filter using the second RCD value. The third PCD filter and the fourth PCD filters are used to generate and send two CD pre-compensated optical signals to the second transceiver, which provides tunable CD pre-compensation capability.
