Unshielded Twisted Pair Cables (UTP)

A pair of unshielded wires wound around each other is known as Unshielded Twisted Pair Cables (UTP).

An UTP is a pair of copper wires would by plastic insulators. Unshielded Twisted Pair Cables (UTP) is the cheapest form of cables available for networking purposes. It is highly used in Local Area Network (LAN) environments. The installation cost of the cable is very cheap as it is easy to install.

Electronic Industries Association (EIA), Telecommunications Industries Association (TIA) and American National Standards Institute (ANSI) are the organizations which have defined standards for Unshielded Twisted Pair Cables (UTP) cabling. The ANSI/EIA/ The 568 commercial Building Wiring Standards define various types of cables to be used for various purposes. The cables are divided into different categories namely:

Category 1 - Defines a traditional UTP cable. It is designed to carry only voice and not data. This type of cable is not recommended for networking purposes and is used in telephony services.

Category 2 - Defines a cable that can carry data up to 4 Mbps. It consists of 4 pairs of wires.

Category 3 - Defines a cable that can carry data up to 10 Mbps. It consists of 4 pairs of wires. It is 1000 feet in length with marks of length at every 2 Feet. The frequency of this cable is 16 MHz. It's used for 10Base T network.

Category 4 - Defines a cable that can carry data up to 16 Mbps. It cable consists of 4 pairs of wires. The signaling frequency of this cable is up to 20 MHz.

Category 5- Defines a cable that can carry data up to 100 Mbps. The signaling frequency of this cable is up to 100 MHz. This type of cable is primarily used in today's networking environment. The cable is used in 100baseX, ethernet architecture and Asynchronous Transfer Mode (ATM) architectures.

Category 5e - Defines a cable that can carry data up to 1000 Mbps with a signaling frequency of 100 MHz. It is used to connect computers, hubs, switches and print servers.

Category 6 - Defines a 4-pair cable that provides an improved performance as compared to Cat 5e. Data is transferred at the rate of 1000Mbps with a signaling frequency of 250 MHz.

Category 7 - Defines a fully shielded twisted pair cable that operates at the signal frequency of 600 MHz. Fully shielded means all the four pairs of a cable have additional shield over them.

MBps stands for Mega Bytes per second and Mbps stands for Mega Bits per second.

Both terms are different as 1 Byte = 8 Bits.

Advantages of Unshielded Twisted Pair Cables (UTP)

• Cheapest form of cable available for networking purposes.

• Easy to handle and install.

Disadvantages of Unshielded Twisted Pair Cables (UTP)

• Highly prone to external interference like EMI and RFI.

• Highly prone to crosstalk.

• Unable to provide secured transmission of data.
