1000Base-T (IEEE 802.3ab)

1000Base-T is a specification for Gigabit Ethernet over copper wire (IEEE Std. 802.3ab). This standard defines 1 Gb/s data transfer over distances of up to 100 meters using four pairs of CAT-5 balanced copper cabling and a 5-level coding scheme.

1000Base-T Benefits

Because many companies already use CAT-5 cabling, 1000base-T can be easily implemented. Other 1000Base-T benefits include compatibility with existing network protocols (i.e. IP, IPX, AppleTalk), existing applications, Network Operating Systems, network management platforms and applications.
