Gigabit Ethernet is defined in
IEEE Standard 802.3, 1998 Edition. "Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer Specifications." See Chapters 3, 4, and 34–39.
IEEE 802.3-ab-1999. "Physical Layer Parameters and Specifications for 1000 Mb/s Operation Over 4-Pair of Category 5 Balanced Copper Cabling, Type 1000BASE-T."
The fibre channel physical layer is described in
ANSI Standard X3.230-1994 (FC-PH). "Information Technology—Fibre Channel—Physical and Signaling Interface."
