Twisted Pair Cable One network Different types of cables are used, with the help of which electronic devices are connected to each other so that data can be exchanged. As coaxial cable, fiber optics cableTwisted Pair Cable.
We have already told you about Coaxial Cable and Fiber Optics Cable, through today’s article we will know what is Twisted Pair Cable and its types.
Twisted Pair Cable Small networks such as LAN is very important for Data The transfer speed is very high. To get complete information about Twisted Pair Cable, you have to read this article till the end.
So let’s start this article first of all – Twisted Pair Cable What is in Hindi.
What is Twisted Pair Cable?
Twisted Pair Cable (twisted pair cable) is such a cable in which two wires or wires are twisted with each other. Copper wire is used in this type of cable, because copper is a good conductor of electricity. Plastic coating is done from outside of these copper wires. Due to the twisted wires, they transmit data very fast.
Twisted Pair Cable is used to establish communication between many types of electronic equipment. Twisted Pair Cable is mostly used in making LAN.
Types of Twisted Pair Cable
Twisted Pair Cable is mainly of two types –
- Unshielded Twisted Pair (UTP)
- Shielded Twisted Pair (STP)
1 – Unshielded Twisted Pair (UTP)
Unshielded Twisted Pair consists of 4 Pair wires and Shield is not used to protect all Pairs in it. It is mostly used for telephone wire and ethernet network is done in In most cases, UTP cables are installed with RJ-45 connectors.
Earlier UTP was considered as a medium for transmitting slow data, but with time it got further upgraded and today UTP is considered a fast medium for transmitting data.
Types of Unshielded Twisted Pair (UTP)
UTP cables are divided into different categories,
Category 1 This type of cable is not used in networking, it is used in telephone line, because these cables are made to transmit voice.
Category 2 – This type of cable is also used in networking, but their speed is very slow. They can transmit data at a speed of only 4 megabits per second (Mbps).
Category 3 – UTPs of this category are capable of transmitting data at a speed of 10 Mbps. Their frequency is 16 MHz.
Category 4 – Category 4 cables can transmit data at a speed of 16 Mbps. Their frequency is 32 MHz.
Category 5 – Category 5 cables are capable of transmitting data at a speed of 100 Mbps. Their frequency is up to 100 MHz.
Category 5e – This type of UTP can transfer data at a speed of 1000 Mbps. These are used for Gigabit Ethernet.
Category 6 – Category 6 UTP cables are capable of transmitting data at a speed of 1000 Mbps. Their frequency is 250 MHz.
Category 7 – Category 7 UTP cables are capable of transmitting data at speeds of up to 10 Gbps up to 100 meters. These cables operate at a signal frequency of 600 MHz. These Built for Gigabit Ethernet and 10G networks.
Advantages of Unshielded Twisted Pair (UTP)
- UTP cable is the cheapest of the cables available for building a network.
- Able to transmit data at high speed.
- There is a useful cable for the exchange of information in the LAN network.
- Installing UTP cable is very easy.
Disadvantages of Unshielded Twisted Pair (UTP)
- External interference is more in UTP cable.
- There is more crosstalk in this.
- Unable to broadcast data securely.
2 – Shielded Twisted Pair (STP)
Shielded Twisted Pair cables also have 4 pairs of wires, and each pair of wires is wrapped in a protective thin foil to protect them from cross talk. To protect these wires from external interference, an outer metal foil is placed over the two twisted copper wires. STP cables have an additional coating on the outside that protects the cable from electromagnetic interference.
STP cable is mostly used to build a network. Because these cables provide more security than UTP.
Shielded Twisted Pair (STP) Type
STP cables are divided into two categories.
5e category , This type of STP cable has a data transmission speed of 1000 Mbps and operates at a frequency of 350 MHz. 5e STP cables are beneficial for transferring data in networking and for telephone lines.
150 Om shield cable , These types of STP cables are protected from crosstalk and external interference, as they have an additional coating on the outside. They can work at a maximum frequency of 16 MHz.
Advantages of Shielded Twisted Pair (STP)
- Crosstalk is less in STP cables.
- It is protected from any outside interference.
- STP cables are capable of transmitting data securely.
- The data transfer speed of STP is higher as compared to UTP cable.
Disadvantages of Shielded Twisted Pair (STP)
- STP is complicated to install as compared to UTP.
- The cost of STP cable is also higher than UTP.
- STP cables are heavy.
Difference between UTP and STP
We have told you the difference between Unshielded Twisted Pair and Shielded Twisted Pair cable through the table below which will make it easy for you to understand.
|Unshielded Twisted Pair (UTP)||Shielded Twisted Pair (STP)|
|In UTP cable only twist is done.||In STP cable, the wires are twisted and the foil or mesh shield is wrapped over them.|
|Data transfer rate in UTP is slow.||The data transfer rate in STP is much higher than UTP.|
|Crosstalk and external interference are more in UTP cables.||STP cables do not have crosstalk and external interference.|
|UTP cable is unable to broadcast data securely.||Data can be broadcast securely in STP cables.|
|Installing UTP cable is very easy.||The process of installing an STP cable is a bit complicated.|
|UTP cable does not require much maintenance.||STP cable requires more maintenance.|
|Noise is more in UTP cable.||Noise is less in STP cable.|
Common Questions Related to Twisted Pair Cable
