This issue only applies to the stand-alone RS-FEC core example design and does not affect the RS-FEC core itself or any cores such as the 25G/50G/100G Ethernet Subsystems that use the RS-FEC as a subcore. As the Ethernet industry continues to innovate and lay a path to higher networking speeds like 100GbE, 25GbE has been developed to provide a simpler path to future Ethernet speeds of 50 Gbps, 100 Gbps and beyond. Reed-Solomon codes use symbols and codewords, rather than bytes and frames, to correct symbol errors rather than bit errors. Many Ethernet connections have been based on the NonReturn- -to-Zero (NRZ) line code, which transfers 1 bit per sent symbol.
