Abstract
Embodiments of the present disclosure relate to a method and apparatus for optical communication. For example, there is provided a method implemented at a passive optical network device configured to perform high-rate communication via a bandwidth-limited link. The method comprises: receiving, via the bandwidth-limited link, a training signal from an optical network unit; obtaining a delay signal by delay-sampling the training signal; determining, based on the delay signal, a first channel response of the bandwidth-limited link, the first channel response characterizing change of the training signal caused by the bandwidth-limited link; and compensating, based on the first channel response, a communication signal received via the bandwidth-limited link from the optical network unit, to reduce distortion of the communication signal. A corresponding apparatus is also disclosed.
