Abstract
Embodiments of the present disclosure relate to a method, a device, an apparatus for optical communication and computer-readable medium. The method comprises receiving, at an optical line terminal, an access request from a first optical network unit; in accordance with a determination that the first optical network unit is not registered at the optical line terminal, obtaining a first parameter set from the first optical network unit, and updating an association relationship between a distorted signal received at the optical line terminal and an original signal recovered from the distorted signal, based on the first parameter set. In this way, regarding different levels of optical signal quality attenuation caused by optical network units with different channel responses in one passive optical network, a unified signal compensation scheme can be provided for all optical network units, in order to mitigate transmission distortion of signals on an uplink of optical communication and significantly reduce configuration overheads in practice.
