Efficient Computation and Compensation of Distortion in Dispersion-Managed Optical Communications

Technology Benefits

Reduced computational load with equivalent compensation, compared to currently available technologies

Technology Application

Dispersion-managed optical communications, particularly transoceanic systems

Detailed Technology Description

This method of nonlinearity compensation begins with a dispersion-managed optical signal transmitted over an optical communication link and virtually divides the communication link into multiple steps. Next, performing lumped dispersion compensation on a received optical signal obtains a waveform upon which digital backward propagation is applied by performing dispersion compensation and nonlinearity compensation for each of the multiple steps derived from the communication link, generating an estimate of the transmitted signal base.
