Patent ID: 11290207

Abstract:
Optical transmitter apparatus (100) comprising: a transmitter optical subassembly (130) configured to transmit forward error correction, FEC, codewords on an optical carrier signal; a memory device (110) containing local configuration data; and processing circuitry (120) 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.
