Abstract
Optical transmitter apparatus () comprising: a transmitter optical subassembly () configured to transmit forward error correction, FEC, codewords on an optical carrier signal; a memory device () containing local configuration data; and processing circuitry () configured to: receive client signal data and perform FEC encoding on the client signal data to form a sequence of FEC codewords; receive local configuration data from the memory device; obtain a configuration payload pattern of FEC codewords having a FEC code violation and FEC codewords not having a FEC code violation, the configuration payload pattern representing the local configuration data; create FEC code violations within FEC codewords of said sequence according to the configuration payload pattern to form a configuration payload modified sequence of FEC codewords; and provide the configuration payload modified sequence of FEC codewords to the transmitter optical subassembly for transmission.
