Wiring: thin coax

An alternative to twisted-pair

wiring is thin coaxial cabling,

often called thin coax. This

cabling is known as RG-58A or

RG-58U cable, and has an

impedance of 50 ohms. (It looks

similar to the 75-ohm thin

coaxial cable used in television

installations, but the television

cable will not work in a network.)

The connectors used with thin

coax are BNC connectors. The

cable is a continuous cable, up to

185 meters (606 feet) long, made

up of shorter segments with BNC

connectors at each end. It

connects to computers and other

devices along its length using

BNC "T" connectors, and there is

a 50-ohm terminator at each end

of the cable. This cabling scheme

does not use a hub.

A thin coaxial LAN operates at a

data rate of 10 mbps (megabits

per second), and is known as a

type 10Base2 network.
