In multi pair cable sets, for example a Cat. 5 cable, the wires of each pair are twisted to prevent mutual induction into the other cable pairs. The tighter the twist, the less amount of induction into the other cable pairs.

I believe it has the benefit of avoiding "cross talk" from the wires near each other, the twisted pair makes it less likely. I think it also has the benefit of having two wires on one connection for more potential through-put?


You use a Rj-45 connector with twisted-pair cabling in an Ethernet LAN. Rj-45 is a connector with a 4 5 wiring sequence.



The connector used with twisted pair cabling in an Ethernet LAN is an RJ-45 connector. The RJ-45 connector is also known as an 8P8C modular connector.


Unshielded Twisted Pair (Cat 5 network cabling)


UTP cables are Unshielded twisted pair cables.they uses twisted pair of wires to cancel out the electromagnetic interference and cross talk bw two wires . most common seen example of twisted pair cable is CAT 5 cable.This type of cable is used in structured cabling for computer networks such as Ethernet and ATM, and is also used to carry many other signals such as telephony and video.


To avoid the short circuit between two wires it is twisted.



Fiber optic cablingAnswer Explanation: Unlike coaxial cabling, unshielded twisted pair (UTP) cabling, and shielded twisted pair (STP) cabling, fiber optic cabling is not susceptible to eavesdropping. An eavesdropper would have to actually cut the line and tap into the fiber optic cable with a highly complex form of optical T-connector. This would interrupt the connection, which should immediately trigger an alarm.The "Unshielded twisted pair cabling" and "Shielded twisted pair cabling" options are incorrect. Twisted pair cabling is susceptible to eavesdropping because information is transmitted through the cable via electrical pulses, which emit small amounts of electromagnetic radiation. An eavesdropper could intercept communications with the proper equipment.The "Coaxial cabling" option is incorrect. Coaxial cabling is susceptible to eavesdropping because anyone can tap into it and add an unauthorized device. Since connections to the network cannot be controlled by a switch or hub, there is no way to prevent unauthorized connections. An intruder can tap into the network with either a basic T-connector or vampire tap.


better over long distances better error performance more secure


A type of cable that consists of two independently insulated wires twisted around one another. The use of two wires twisted together helps to reduce crosstalk and electromagnetic induction. While twisted-pair cable is used by older telephone networks and is the least expensive type of local-area network (LAN) cable, most networks contain some twisted-pair cabling at some point along the network. Other types of cables used for LANs include coaxial cables and fiber opticcables.


Its cheaper, more flexible and can be made to any impedience (VSWR matching for antennas)


it is not UPT ,it is UTP which stands Unshielded Twisted Pair. The UTP is mainly used for network cabling i.e; LAN cabling.


Dunno. "Quad" usually refers to the shielding (such as TV antenna coaxial cable), "CAT" usually refers to four-pair twisted pair. "CATn" (CAT3~CAT6) is four-pair, twisted-pair, unshielded cabling most commonly used in Ethernet computer network cabling. Refine the question, we can help out.


performs better over long distances provides better error performance more secure


There are 8 wires total, 4 wire pairs.


There are 4 pairs, 8 wires in total.


____ is the most popular cabling method for local networks.Answer: Twisted-pair cable


It covers short distance and no security.


Twisted pair cabling is based on copper wire; fiber optic cable is not twisted and uses a glass or plastic wire with light pulses rather than electrical voltage.
