Abstract
A method of providing forward error correction on an Ethernet point-to-point link, constituted of: receiving at one end of the point-to-point link an input data stream, wherein the input data stream is a 10 bit symbol encoded serial data stream at a first data rate; decoding the 10 bit encoded data stream to a 9 bit symbol data stream; increasing the data rate of the 9 bit symbol data stream to a second data rate; for each segment of a predetermined number of 9 bit symbols generating a respective plurality of parity symbols; combining the segments and the generated respective plurality of parity symbols into FEC appended segments; encoding the FEC appended segments into an output 10 bit symbol encoded data stream; and transmitting the output 10 bit encoded stream on the point-to-point link at the second data rate.
