    Abstract: A marker spacing between two consecutive alignment marker (AM) blocks is defined for virtual lanes in a multi-virtual-lane networking protocol. A system using the networking protocol includes circuitry configured to identify virtual and physical lane groupings and numbers based on the AM blocks. The system may use error coding groups to allow for distribution of the AM blocks to the physical lanes in integer numbers of error correction blocks. The identification scheme may be based on sequences derived from a known bit pattern and the bit inverse of the bit pattern. The system may include matching units identify instances of the bit pattern and its bit inverse.

    Abstract: Communication device employing binary product coding with selective additional cyclic redundancy check (CRC) therein. Product code encoding (e.g., employing row and column encoding of matrix formatted bits, selectively with interleaving and/or permutation of the bits therein) may be combined with additional error correction code (ECC) or forward error correction (FEC) coding thereby generating coded bits for use in generating a signal to be launched into a communication channel Various ECCs/FECs may be employed including a BCH (Bose and Ray-Chaudhuri, and Hocquenghem) code, a Reed-Solomon (RS) code, an LDPC (Low Density Parity Check) code, etc. The redundancy of such coded signals as generated using the principles herein is in the range of approximately 7%, and hard decision decoding may be performed on such coded signals generated herein. In accordance with decoding such signals, various bit decisions (within certain iterations) may be selectively ignored and/or reverted back to previous bit decisions.
