This PCS leverages the 64B/66B coding scheme that was originally used in 10 Gigabit Ethernet, but also transcodes a group of four 66-bit codewords down to 256B/257B codewords to further reduce the coding overhead and to create extra room for FEC.
WebPMD defines specifications for the physical layer of a network standard, namely, the media and interface connectors used. As FDDI supports both fiber and copper media, two separate specifications are defined. They … WebBasic line encoding (4b/5b, 8b/10b, 64b/66b group codes) is done in PCS, with PMD doing some additional, medium-specific coding (e.g. MLT-3) Auto-negotiation somewhat …
