Cabling Requirements 8310BASE-T Operation10BASE-T is the Institute of Electrical and ElectronicsEngineers (IEEE) 802.3 standard for Ethernet signalingover unshielded twisted-pair wire at 10 Mbps.Ethernet, as the most widely used network protocol,uses 10BASE-T as its primary cabling scheme. Ethernetcharacteristics include: A data rate of 10 Mbps. A broadcast architecture. A specific media-access control (MAC) scheme.The 10BASE-T name indicates a signaling speed of10 Mbps and twisted-pair wiring. Base stands forbaseband, which denotes a technique for transmittingsignals as direct-current pulses rather than modulatingthem onto separate carrier frequencies.A wiring topology using 10BASE-T specifies a wiringhub, cable arranged in a star configuration, and unshieldedtwisted-pair cable. Each node has a separate cable run thatmust not exceed 100 meters (328 ft) from the node tothe hub.Category Use1 Traditional telephone cable.2 Data transmissions up to 4 MHz.3 Voice and data transmission up to 25 MHz. The cabletypically has four pairs of wires. Category 3 is themost common type of installed cable found in oldercorporate wiring schemes.4 Voice and data transmission up to 33 MHz. The cablenormally has four pairs of wire. This grade of UTP isnot common.5 Voice and data transmission up to 125 MHz. The cablenormally has four pairs of copper wire and three twistsper foot. Category 5 UTP is the most popular cableused in new installations today.
