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
