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

If you plan on using gigabit ethernet, you'll need Cat 5e (Category 5e) wiring. Fast Ether; Gigabit Ether Connectivity Technology : N/A Networking / Compliant Standards : IEEE 802.3 IEEE 802.3u IEEE 802.3ab Cabling Type : Ether 10BASE-T; Ether 1000Base-T; Ether 100Base-TX Features : Auto-uplink (auto MDI/MDI-X ) half duplex mode full duplex mode Dimensions&MiscellaneousWidth : 8 Inch Depth : 9 Inch Height : 1.8 Inch Network Hardware; Network Adapter / Gigabit Ethernet Catalyst 3560 v2 Series Standard Image Catalyst Sw.. It is compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.3z and IEEE Std 802.3ab. 10BaseT and 100BaseT use two wire pairs 13. The primary standard for gigabit today is 1000Base-T, or IEEE 802.3ab. The docs below IEEE 802.3u standard clause 28 (for Fast Ethernet) IEEE standard 802.3z Standard clause 37 (for Gigabit Ethernet)". Technology improvements, and better interoperation of autonegotiation make it the preferred mode of operation, and is required on new technologies such as 1000BASE-T (802.3ab). IEEE Std 802.3aa-1998, Maintenance #5 . 1000Base-T runs over twisted-pair copper wiring. The Cisco Catalyst 2970G-24T Switch is affordable Gigabit Ethernet switch that deliver wire-speed intelligent services for small and medium businesses and enterprise branch offices. Gigabit ethernet doesn't even officially support anything but autonegotiation. The 1000BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features. IEEE 802.3ab describes 1000BaseT which is known as Gigabit Ethernet and uses four pair UTP cabling to achieve gigabit performance. 1000BaseLH, also known as 1000Base-LH, is a specification for Gigabit Ethernet over fiber optic cabling as defined in IEEE 802.3z. What is the standard IEEE 802.3ab? ANSI/IEEE Standard 802.2, 1998 Edition is available online at the Get IEEE 802™ home page IEEE Std 802.3z-1998, Gigabit Ethernet . IEEE Std 802.3ab-1999, 1000BASE-T . "The IEEE 802.3 standard default is to run with autonegotiation enabled. LH stands for The 1000BASE-T standard is defined in the IEEE 802.3ab.
