A twisted-pair cable is a cable made by intertwining two separate insulated wires. There are two twisted pair types: shielded and unshielded. A STP (Shielded Twisted Pair) cable has a fine wire mesh surrounding the wires to protect the transmission and a UTP (Unshielded Twisted Pair) cable does not.

WHAT IS TWISTER PAIR CABLE?

A twisted pair cable is a type of cable made by putting two separate insulated wires together in a twisted pattern and running them parallel to each other. This type of cable is widely used in different kinds of data and voice infrastructures.

ITS PERFORMANCE AND CHARACTERISTICS

twisted pair has a more accommodating bend radius, is easier to terminate, and provides more versatility in selecting network topologies.

CATEGORIES AND ITS COMPARISON

Two different types of twisted pair cable, unshielded twisted pair (UTP) and shielded twisted pair (STP) are used in different kinds of installations.

UTP is common in Ethernet installations, while STP is used in various kinds of networks to prevent crosstalk and electromagnetic interference.

STP cable can also help to provide grounding.

APPLICATIONS AND CROSSTALK

Twisted pair cable is used in various areas, like as –

Ethernet network

Telephone lines

DSL lines

Security camera system

LANs

ADVANTAGES AND DISADVANTAGES

Advantages of Twisted pair cable :

It are often wont to carry both analog and digital data.

It’s relatively easy to implement and terminate.

It is the smallest amount expensive media of transmission for brief distances.

If portion of a twisted pair cable is broken it doesn’t effect the whole network.

Less vulnerable to electrical interference caused by nearby equipment or wires.

It cause interference themselves.

Best performance in short distances.

High-cost performance

Disadvantages of Twisted pair cable :

It result signal distortion in a very effective manner.

Attenuation is very high.

It provides poor security and is relatively easy to tap.

As they a thin so can be easily breakable.

Low durability (must be maintained regularly).

Susceptible to electromagnetic interference (EMI).

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 (unwanted signals in a communication channel) interference can come from other pairs within a cable.

Coaxial cables have metal shielding designed to provide immunity against noise and greater bandwidth. Coaxial cable can transmit signals over larger distances at a higher speed as compared to twisted pair cables.

# data[].attributes.body
One advantage of coaxial over other types of radio transmission lime is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors.

Coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other types of transmission lines.

Coaxial cable provides protection of the signal from external electromagnetic interface.

There are two main types of twisted pair cables:

1.    Unshielded twisted pair (UTP)

2.    Shielded twisted pair (STP), which contains each pair of wires within an aluminium foil shield for further isolation.

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.

On the contrary, STP (Shielded twisted pair) is a twisted pair cable confined in foil or mesh shield that guards the cable against electromagnetic interference.

# data[].attributes.body
In structured cabling, crosstalk refers to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel. Signals traveling through adjacent pairs of wire create magnetic fields that interact with each other, inducing interference in the neighboring pair. The pair causing the interference is called the “disturbing pair”, while the pair experiencing the interference is the “disturbed pair
