Abstract: Systems and techniques for are described herein. An optical signal is received and the optical signal is converted into an electrical signal. The electrical signal is amplified through a trans-impedance amplifier to produce an amplified signal. The amplified signal is normalized using a limit amplifier to generate a normalized signal. Bit values are determined from the normalized signal and a corresponding probability bit is generated for each bit value using a threshold detector. The bit values and the corresponding probability bit are encoded into a four-level pulse-amplitude modulation (PAM-4) signal. The PAM-4 signal is transmitted to an application-specific integrated circuit (ASIC) for data recovery and error correction processing.

Abstract: Systems and techniques for forward error correction decode processing power reduction are described herein. A first codeword is identified in a network transmission. A conditional decoding window is generated that begins with the first codeword. The conditional decoding window is aligned with a frame of the network transmission. A report is generated that includes an indication of relevance of the conditional decoding window to a network device. The conditional decoding window and the report are transmitted to the network device. A conditional decoding window is received that includes a first codeword. The first codeword is decoded to determine a second codeword. A report is obtained that includes a codeword relevance bit for the second codeword. Upon a determination that the codeword relevance bit indicates that the second codeword is irrelevant, the second codeword is discarded without decoding the second codeword.
