Optical transceiver with dispersion management

An optical transceiver, comprising:

• a digital signal processor;
• a transmitter coupled to the digital signal processor;
• and
• a receiver coupled to the digital signal processor, the receiver configured to receive an optical signal, the receiver including:
• a plurality of demultiplexers, each of the plurality of demultiplexers configured for optical demultiplexing of the optical signal into a plurality of channels;
• and
• a plurality of dispersion management devices for each of the plurality of demultiplexers, each of the dispersion management devices being associated only with a respective edge channel of the plurality of channels of the respective demultiplexer and configured for dispersion compensation at the respective edge channel, without dispersion compensating a middle channel of the plurality of channels,
• wherein each of the dispersion management devices includes a thermal control component configured to thermally adjust the dispersion compensation by the dispersion management device based on an output of the digital signal processor.

A receiver for an optical transceiver, the receiver configured to receive an optical signal, the receiver comprising:

• a demultiplexer for optical demultiplexing of the optical signal into a plurality of channels;
• and
• a plurality of dispersion management devices, each of the dispersion management devices being associated only with a respective edge channel of the plurality of channels of the demultiplexer and configured for dispersion compensation at the respective edge channel, without dispersion compensating a middle channel of the plurality of channels,
• wherein each of the dispersion management devices includes a thermal control component configured to thermally adjust the dispersion compensation by the dispersion management device based on an output of a digital signal processor of the optical transceiver.
