Why are twisted pair cable used in telephone line?
Twisted-pair cable is a type of cabling that is used for telephone communications and most modern Ethernet networks. A pair of wires forms a circuit that can transmit data. The pairs are twisted to provide protection against crosstalk, the noise generated by adjacent pairs.
What is the advantage of twisted copper cable?
Compared to a single conductor or an untwisted balanced pair, a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves rejection of external electromagnetic interference.
What are 3 advantages of twisted pair cable?

- Twisted-pair cable and Twisted-pair transmission own obvious advantages such as function / price rate.
- The Advantages of the Twisted-pair transmission.
- 1) Long transmission distance, High transmission quality.
- 2) Wiring convenient, high using rate of cable.
- 3) Strong anti-interference ability.
What are the advantage and disadvantages of shielded twisted pair cable?
➨It has higher cost per foot of wire. ➨Shield of STP cables must be grounded properly otherwise it acts like an antenna and picks up unwanted signals. ➨There is no improvement in segment length despite its thick and heavier construction. Also refer advantages and disadvantages of UTP cable >>.
What is the purpose for the twists in twisted pair Ethernet cabling?
The primary purpose of the twists is to reduce internal electrical-interference. In effect, Ethernet cable comes with its own built-in “shielding”. Now, wait a minute! You might be thinking that unshielded Ethernet cable has no shielding, and shielded Ethernet cable is the type that has shielding.
Are telephone lines twisted pair?
What Do ‘Pairs’ Mean in Telephone Cables? Every conductor within this kind of cable is twisted together with another in an insulated, colour-coded unit.
Why is twisted pair cable twisted?
Twisted pairs are made up of two insulated copper wires that are twisted together. The twisting is done to help cancel exterior electromagnetic interference. Crosstalk interference can come from other pairs within a cable. Coaxial or optical fibre options deliver greater bandwidth in comparison to twisted pair cabling.
Why do you think is the reason why a shielded twisted pair has foils and overall shield Unlike UTP?
STP cables incorporate a conducting shield built of metallic foil enclosing the twisted wire pairs, which obstructs out electromagnetic interference, permitting it to carry data at an enhanced rate of speed. In contrast, UTP provides less speed of data transfer.
What is the purpose for the twist in twisted pair Ethernet cabling quizlet?
A copper cable type that uses twists of pairs of copper wire to reduce / eliminate crosstalk and other electromagnetic interference.
What are the advantages of twisted pair cable?
Twisted pair cable reduces the impact of electromagnetic interference on electronic signals, so it is suitable for short-distance data and voice infrastructure. Compared with coaxial cable, it is also more flexible and easy to install.
Why is a Twinn cable twisted?
Twin wire or cable is twisted because a high frequency signal on a wire generates a magnetic field that can induce a signal on an adjacent wire. These induced signals are called “crosstalk”, because with old analog telephone lines, you could often hear other conversations in the background of your call resulting from these induced signals.
What happens when a wire is twisted to transmit data?
One of the wires is used to transmit data and the other is the ground reference. All transmissions are prone to noise, interferences, and crosstalks. When the wires are twisted, some part of the noise signals is in the direction of data signals while the other parts are in the opposite directions.
What is the difference between twisted wire and balanced wire?
Twisted wires or cable acts as low parasitic capacitance shielded cable, while balanced not-twisted line does not. This type of cable is widely used in different kinds of data and voice infrastructures. Cyber espionage is on the rise.
