Twisted Pair Cables are available with two insulated copper wires twisted with each other to form a single wire. These wires are twisted together to block the electromagnetic interferences and losses. These cables are mainly used for telephone and radio signal transmission. Twisted pair cables are commonly used as shielded twisted pair (STP) and unshielded twisted pair (UTP) to transmit balanced signals. These cables are used to transmit signals on high bandwidth to reduce electromagnetic induction and crosstalk.
Twisted pair cables are available in different colors and contain wires with Foil Type pairs (FTP). These cables are used to provide network on LAN cables and rather then these cables coaxial cable and fiber optic are also used to provide network. These cables are insulated with aluminum and grounded to transmit signals. The main applications of these cables are telecommunication and television industries.
Types of twisted pair cables:
Shielded Twisted Pair: This cable contains two copper wires twisted with each other and wrapped with aluminum foil to provide signal transmission without any electromagnetic interference and crosstalk. This cable is mainly used to connect many business computers and telephones. This cable is very much flexible because of copper wire insulation.
Unshielded Twisted Pair: UTP cable is most popular cable used for computer networking. It contains two wires which are shielded and twisted with each other to block interferences. This wire is mainly used for traditional telephone lines and available in various categories like CAT1, CAT2, and CAT3 etc. This wire is very easy to install and transmits more reliable signals at high bandwidth. This cable is more flexible as it contains copper wires and available in very low cast. It is widely used for local area networks.
These cables are easy to use and available in very low cost
Available in different colors and lengths
Widely used to block electromagnetic interferences and crosstalk
Provide faster speed in comparison with other cables
More flexible because if copper wire insulation
Available with long diameters to be used for short distance with higher bandwidth.
STP cable is more expensive then twisted pair cable
STP cable is hard to install in comparison with UTP cable
A thick coaxial cable is hard to fold and provide less flexibility
This cable do not work during climatic changes
Less reliable if not grounded perfectly
Twisted pair cable is available as UTP and STP. It is commonly used in telephone and TV industry as it is easy to install and provide more reliable signals. Use of this cable is easy and safe.
