Network Cable
10BaseT
Shielded / Unshielded Twisted Pair cable uses a phone jack type connector (RJ-45) and is
similar to telephone cable, but is a higher grade of specification. Twisted pair cable consists
of two strands of copper wire twisted together in separate sheaths. STP is shielded by foil,
which gives the cable a very good resistance to outside interference but makes the cable
more expensive and heavier. UTP is an unshielded version, which is now becoming very
common. The standard for STP/UTP specifies that data can be transmitted at 10 MBPS for
up to 100 metres (about 328 feet). More recently, the highest grade of STP/UTP can now
allow speeds of up to 100Mbps over 100 metres in length. The minimum cable length
between computers is 2.5 metres (about 8 feet). This cable can be directly attached to the
network card of the AR5132.

10Base2
This type of cable is known as Thinnet, Cheapernet, or thin wire, because of the thin
inexpensive coaxial cable (RG-58) that it uses. The cable is very similar to that used as
aerial cable in the back of your television sets. It consists of a central conductor surrounded
by an insulation layer, a wire mesh shielding layer and a non-conductive outer shield. This
has long been the common cabling standard for Ethernet installations. Data can be
transmitted at 10Mbps and can carry a signal roughly 2 x 100 metres (185 metres or 607
feet). The minimum cable length between computers must be at least 0.5 metres (20 inches)
long. This cable can be directly attached to the network card of the AR5132.

10Base5
This cable is classed as standard Ethernet. It is similar to Thin Ethernet however is a higher
specification cable. It has a very good resistance to outside interference but is expensive,
especially at large diameters. It is also heavy and inflexible so making it difficult to install.
This cable can transmit at rates of 10 MBPS and can carry a signal for up to 500 metres
(1640 feet). It can support as many as 100 nodes (workstations, repeaters and bridges)
per backbone segment. The minimum cable length between workstations is 2.5 metres
(about 8 feet). Drop cables are used to connect workstations to Thick Ethernet cable and
can be as long as 50 metres (about 164 feet).

Fibre Optic Cable
This cable uses a thin flexible glass fibre, which is surrounded by a sheath. This cable is
capable of very high data rates and bandwidth over long distances, but has the disadvantage
of special converters to attach devices to it. Light is used to send data from one end of the
network to the other by the use of small lasers. A sensor at the other end detects the laser
light and either converts it in to an electrical signal or passes it on to the next workstation on
the network. Due to its disadvantages, Fibre Optic cable is usually used as a backbone
circuit in an installation with other cabling types connected to it to serve the users.
