oFEC Encoder and Decoder
- OpenROADM oFEC (Open Forward Error Correction) is a core element of the OpenROADM initiative, providing a standardized, open-source FEC solution for high-speed coherent optical networks.
- The oFEC IP cores deliver high coding gain through a fully parallel, pipelined decoder architecture with 3 soft-decision (SD) and 2 hard-decision (HD) decoding steps. It supports data rates from 200G to 800G, including Probabilistic Constellation Shaping (PCS) modes to enhance spectral efficiency, noise tolerance, and transmission reach.
