Abstract

An optoelectronic transceiver module includes a coupler and an optoelectronic transmitter and receiver. The coupler couples one optical waveguide of one optical network. The coupler and network each have a reflection impulse response. The transceiver has a compensator generating an electrical correction signal using characteristic parameters of the reflection impulse response of the coupler and/or optical network and the electrical data signals of the transmitter, and uses the correction signal to correct the data signals received by the receiver. In the method, optical signals are received in a first transceiver from a second transceiver. Characteristic parameters of the reflection characteristics of the optical system coupled to the receiver in the first transceiver are determined, these parameters are used to generate a correction signal from the data signal to be sent from the first transceiver, and an electrical received signal is corrected in the first transceiver using the correction signal.
