Abstract: The provided is a dispersion managed transceiver, including digital signal processor (DSP) and receiver, the receiver is integrated with self-locking dispersion management device (DMD), the dispersion management device performs dispersion compensation on the optical path based on the signal-to-noise ratio (SNR) or bit error rate reading of the digital signal processor. And also provides a modulator, includes the above-mentioned transceiver. And also provides a dispersion compensation method for the transceiver, including the following steps: S1, integrating self-locking dispersion management device in receiver; S2, achieving self-locking of the optical path based on the signal-to-noise ratio or bit error rate reading from the digital signal processor, and compensating the dispersion of the optical path; S3, after compensation, counteracting different fiber chromatic dispersion values from different fiber lengths.

Abstract: In one embodiment, a method for dispersion compensation by an optical transceiver includes: receiving an output from a digital signal processor of the optical transceiver; determining a difference between the received output and an initial target output; based on determining that the difference between the received output and the initial target output exceeds a threshold, tuning a temperature of a dispersion management device of the optical transceiver across a first temperature range; identifying an adjusted target output based on the temperature tuning across the first temperature range; and adjusting the temperature of the dispersion management device to an adjusted target temperature corresponding to the adjusted target output.

Abstract: In one embodiment, an optical transceiver includes a digital signal processor, a transmitter coupled to the digital signal processor, and a receiver coupled to the digital signal processor. The receiver is configured to receive an optical signal. The receiver includes 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 is associated with a respective channel of the plurality of channels of the demultiplexer and is configured for dispersion compensation at the respective channel. 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.
