What technique is used with UTP cable to help protect against signal interference from crosstalk?
Explanation:
To help protect against signal interference from crosstalk the technique used by the UTP cable is to twist the wires into pairs because it will create the magnetic field of each wire which cancels the effect of each other.
What is UTP?
UTP (unshielded twisted pair cable) is an omnipresent copper cable type that is common in telephones wiring or the local area networks. Unshielded cable has a total of five types which are identified with the prefix CAT and each has different bandwidth. The connector for the UTP cables is RJ-45.
Other cables like the coaxial cable and the fiber optic cable have their benefits and cons but UTP is the most useable cable because of its cost and the setup of installation is easy compared to others.
Working of the UTP cable:
The UTP cable consists of four twisted pair of copper wires, which are surrounded in the plastic cover along with various pair which depends on the bandwidth. The wire is twisted to each other and then, they are further twisted together to prevent the crosstalk and the EMF of wires individually because they can reduce the performance of the network. The signal in UTP requires both wires.
The cables have their color code so it is easy to identify the pair. The basic colors are blue, orange, brown, and gray. And they are twisted with other colors such as white, red, black, yellow, or violet. one wire in a pair consists of a solid color and the other is with the suitable one. Such as the blue solid wire is paired with white-blue striped wire for easy identification. The pair cable is designed by alexander graham bell in 1881. different user needs different pairs such as analog, digital, or Ethernet.
UTP cable types
There are a total of five UTP cables which are discussed in the following:
CAT 3: the cable is not as common in today’s world it is implemented in phones the support is 10Mbps up to 100 meters.
CAT 4: it is common in the token ring and the CAT4 is 16Mbps within the range of 100 meters.
CAT5: it is common in Ethernet-based LANs consist of the two pairs which are twisted together the support is 100 Mbps in the range of 100 meters.
CAT5e: it is also present in Ethernet LAN but has four pairs of the cable. the support is 1G bps up to 100 meters
CAT 6: it is common in the Ethernet LAN and the central network for Data it has four twisted-pair cables the support for 100 meters is 1 Gbps while for 50 meters it is 10 Gbps.
The most common technique used to protect against crosstalk interference on UTP cable is twisted-pairing, which involves wrapping the wires within the cable into pairs that are tightly twisted together. This technique helps to reduce the amount of electromagnetic interference that can be caused by crosstalk.
