Signal Processor for Compensating for Optical Fiber Chromatic Dispersion

A signal processor comprising:

• an encoder to encode a source signal received from a data source;
• a splitter to separate the encoded signal from the encoder into an in-phase component and an in-quadrature component;
• a first filter to receive the in-phase component;
• a second filter to receive the in-quadrature component;
• and
• the first filter and the second filter configured to filter the in-phase and in-quadrature components, respectively.
