An optical transceiver capable of optimizing the performance of the corresponding optical channel by dynamically adjusting the optical power of the output signal in response to the FEC-performance data received from the corresponding remote transceiver. In an example embodiment, the FEC-performance data can be exchanged by the two optical transceivers using a dedicated field in the overhead of the transmitted data frames. The power-adjustment process is configured to be relatively slow to prevent the occurrence of transients on other optical channels and ensure stable operation of the corresponding WDM system as a whole, while different transceivers thereof are allowed to adjust their respective output powers in an autonomous way and independent of each other. The performance optimization can be directed at meeting a predefined performance target specified by the system designer or operator while driving the operating point away from conditions under which nonlinear optical effects may become relatively prominent.
