Patent abstract
Systems and methods include receiving blocks of data that has been Forward Error Correction (FEC) encoded via Open Forward Error Correction (OFEC) adaptation; decoding the blocks of data; processing Cyclic Redundancy Check (CRC) data that is included in padding data required in the OFEC adaptation, wherein the padding data is distributed across N rows of payload data; and determining a location of any errors in the payload data based on the processed CRC data. The OFEC adaptation is for mapping the blocks of data into any of a FlexO-x frame structure, a ZR frame structure, and variants thereof, and the location of any errors can be used for error marking.
