Shielded And Unshielded Twisted Pair Cable Diagram

Shielded twisted pair cables may be necessary in those more complex environments.

Shielded and unshielded twisted pair cable diagram. Twisted pair cables with out a shield are called unshielded twisted pairs utp shown to the right. By definition a twisted pair cable is a multi conductor cable and normally a round cable. The diagram above shows an example of a shielded twisted pair cable stp. Recently the advantages and disadvantages of shielded and unshielded twisted pair cable have been under debate.

There are two common types of twisted pair cabling stp and utp. Unshielded twisted pair utp is a ubiquitous type of copper cabling used in telephone wiring and local area networks there are five types of utp cables identified with the prefix cat as in category each supporting a different amount of bandwidth. A cable is a number of such pairs grouped together in a bundle and wrapped in a protective sheath. Alternatives to utp cable include coaxial cable and fiber optic cable there are benefits and tradeoffs to each type of cabling but.

When installing or updating your network infrastructure there are a variety of network patch cable types to consider. Advocates of stp cable which includes screened twisted pair and foil twisted pair cables claim that it is superior to utp cable. Twisted pair shielded and unshielded twisted pair as its name implies consists of a pair of insulated copper wires twisted together to minimize the effects of electromagnetic interference. The s stands for shielded the u stands for unshielded and the tp stands for twisted.

The twist in the wire cancels out any magnetic interference that may develop in the wiring. Unshielded twisted pair utp cables are widely used in the computer and telecommunications industry as ethernet cables and telephone wires. However these advocates have not presented the other side of the story. Shielding is typically made of braided wire mesh or a foil such as mylar wrapped individually around each twisted pair of wires or it may wrap once around the whole group of four twisted pairs in the ethernet cable.

The basic difference between utp and stp is utp unshielded twisted pair is a cable with wires that are twisted together to reduce noise and crosstalk. Twisted pair cables may be shielded or un shielded. Among the choices to be made is whether to install shielded twisted pair cables stp or unshielded twisted pair cables utp twisted pair cabling consists of two conductors of a single circuit twisted together to help reduce electromagnetic interference emi or noise. Unshielded twisted pair utp cables are found in many ethernet networks and telephone systems.

In an utp cable conductors which form a single circuit are twisted around each other in order to cancel out electromagnetic interference emi from external sources.
