Abstract: Systems and techniques for are described herein. A data payload is received. Parity data is removed from the data payload to generate a codeword dataset. Frames are identified in the codeword dataset. Headers of the frames are evaluated using a conditional decoding map. The frames are marked based on a destination in the headers found in the conditional decoding map. A set of target codewords are identified from the frames based on the marking. Remaining frames of the frames outside the set of target codewords are discarded. The set of target codewords is transmitted to a buffer of a conditional decoder. Codewords from the buffer are decoded using the conditional decoder.

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 capacity of a network slice is determined for a user network interface (UNI) based on a subset of forward error correction (FEC) codewords to be decoded by the media access control processor. A number of decoder cores is calculated to decode the capacity of the network slice. A utilization value is determined for a decoder core. A decoder utilization value is calculated for the decoder cores using the utilization value a number of decoding iterations. A non-decoding media access control processor utilization value is obtained for the network slice. A geometry is calculated for the media access control processor using the number of decoder cores, the decoder utilization value, and the non-decoding media access control processor utilization value. A media access control processor manufacturing specification data is generated based on the calculated geometry.

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.
