Optical transmission method and optical receiver

摘要

An optical receiver (OR) has an adaptive optical compensator (OC) and/or an adaptive electrical equalizer (EQ) for compensating signal distortion in a received optical signal. In order to achieve a very fast adaptation of the receiver to the actual signal distortion, which is important for example for bursts mode optical signals in a packet-switched optical transmission network, at least one predetermined trainings sequence (T1, T2) is provided in the optical signal, which is known at the receiver (OR) and thus enables fast adaptation of the compensator (OC) and/or equalizer (EQ) to the actual signal distortion.
