释义 | 100Base-T (100 Mbps; Baseband; Twisted pair) An IEEE standard (802.3u, 1995) similar to 10Base-T, 100Base-T translates to 100 Mbps (theoretical transmission rate), Baseband (one transmission at a time over a single, shared channel), over Twisted pair media.The maximum segment length between the 100Base-T hub and the attached device (e.g., workstation or printer) originally was specified at 100 meters or less over four pairs of Cat 3 unshielded twisted pair (UTP). The predominant version is 100Base-TX, which extends the distance to 350 meters over two pairs of Cat 5e.The 100Base-T hub is a wire hub that serves as a multiport repeater, as well as a central point of interconnection. 100Base-T uses the 4B5B line coding technique.
