IEEE Std 802.3ab (GigaBit Ethernet 1000BaseT)
Publisher: Institute of Electrical & Electronics Enginee

Ethernet Physical Layer: The differences between standard Ethernet, Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet occur at L1, often reffered to as the Ethernet PHY. 10-Gigabit Ethernet (IEEE 802.3ae). Network configuration and design. Fiber is always a point-to-point connection, (between two PC, PC and switch or two switches). My understanding is the IEEE 802.3ab standard (1000BASE-T aka Gigabit Ethernet) was originally developed for use with Cat 5 cabling. IEEE.Std.802.3ab.GigaBit.Ethernet.1000BaseT..pdf. IEEE Std 802.3ab (GigaBit Ethernet 1000BaseT). Same encoding as copper, but signalling is optical. As if 1 Grits/sec wasn't enough, the IEEE is working to define 10-Gigabit Ethernet(sometimes called “10 GE”).
