The First Category 6 Application Has Been APPROVED and published as of June 2001. It is an alternate transmission scheme for 1 Gigabit Ethernet taking advantage of the increased bandwidth offered by Category 6 cabling systems. ANSI/TIA/EIA-854: A Full Duplex Ethernet Specification for 1000Mbit/s (1000BASE-TX) Operating Over Category 6 Balanced Twisted-Pair Cabling is the second standard Telecommunications Industry Association (TLA) published to provide an alternate means of transmitting Ethernet. The first was a short wavelength version of Fast Ethernet for fiber reported in September. In 1999, IEEE published the original and by far predominant Gigabit Ethernet specification as IEEE 802.3ab: Physical Layer Parameters and Specifications for 1000 Mb/s Operation over 4 Pair of Category 5 Balanced Copper Cabling, Type 1000BASE-T. This specification is the basis for all products being shipped today and, for all practical purposes, requires a minimum cabling performance of Category 5e.
