Table 11 lists the cabling specifications for 10-Mbps transmission over UTP and STP cables.

Table 11 Cable Specifications for 10-Mbps 10BASE-T

Parameter	RJ-45
Cable specification	Category 5 UTP 1, 22 to 24 AWG2
Maximum segment length	100 m (328 ft.) for 10BASE-T
Maximum network length	200 m (656 ft) (with 1 repeater)

1.Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially.

2.AWG = American Wire Gauge. This gauge is specified by the EIA/TIA-568 standard.

The Ethernet specifications call the 4E device a transceiver, and it is connected to the station with a transceiver cable. The 4E port adapter is not an end station. The IEEE 802.3 specifications refer to the same type of device as a media attachment unit (MAU) and to the cable as an attachment unit interface (AUI). Only transceiver cables can connect to the 4E ports directly.
