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