This is a term given to any electrical cable that carries Data
related signals. In the past this would have been telephone lines
carrying modem to modem traffic, Then, for a short while thick
or thin co-axial cable for a bus type network. Now it has come
full circle, we are now using a cable made from twisted pairs
of wire - just as telephone cable has always been but to a better
quality. This cable can carry data at speeds of up to 10 gigabits
per second. Its restrictions include a maximum length of 100m
and it must be installed internally only. Data networks between
buildings can be linked with fibre optic cables that can cover
distances of 40Km with the cable completely submerged in water.
Vale Comms & Data Ltd are specialists in installing both twisted
pair and fibre optic cabling.
Cat 5, short for Category 5, is the current preferred industry
standard for data cabling & wiring. Cat 5 is an unshielded
twisted pair type cable exclusively designed for high signal integrity.
The cable consists of four pairs of 24-guage twisted copper pairs
terminating in an RJ-45 jack. If a wire is certified as Category
5 and not just twisted pair wire, then it will have "Cat
5" printed on the shielding.
The actual Cat 5 standard describes specific electrical properties
of the wire, but Cat 5 is most widely known as being rated for
its Ethernet capability of 100 Mbit/s. Category 5 cable comes
with three twists per inch of each twisted pair of 24 gauge copper
wires within the cable. The twisting of the cable helps to decrease
electrical interference and crosstalk. Each wire in a Cat 5 cable
is insulated with a plastic (FEP) which has low dispersion. The
importance of this insulation is that the dielectric constant
of the plastic does not depend mainly on frequency.
Vale Comms & Data also have experience installing and certifying
Fibre optic cables. These are perfect for long distance high speed
data connections. In addition Vale Comms & Data can install
Video cameras and Door entry systems.
