Abstract
In an optical communication system having flexible transceivers, a transmitter section of one of the flexible transceivers generates a modulated pilot signal whose amplitude or phase or both have been modulated according to a digital code. An optical signal is transmitted from the transmitter section to a receiver section of another of the flexible transceivers. The optical signal conveys data and the modulated pilot signal. The digital code encodes parameter information for the transmitter section and for the receiver section. The receiver section receives the modulated pilot signal, determines the digital code by demodulating the modulated pilot signal, and determines the parameter information from the digital code. The transmitter section and the receiver section adjust their configuration according to the parameter information. The receiver section, while configured according to the parameter information, processes received data or future received data.
