UTP (Unshielded Twisted Pair)
UTP (Unshielded Twisted Pair) is a regular copper wire that joins many home and many business computers to the telephone company. UTP is the most common form of twisted pair wiring, because it is less expensive and easier to work with than STP (Shielded Twisted Pair). It is used in Ethernet 10Base-T and 100Base-T networks as well as in home and office telephone wiring.
Twisted pair is frequently linked with home usage. Whereas, an advanced grade of twisted pair is many a times used for horizontal wiring in LAN networks since it is less expensive than coaxial cable.
UTP Cable Standards
The following are a few UTP Cable standards used in the market:
Cat 3 UTP
Category 3 UTP is rated to carry data up to 10Mbit/s.
Cat 3 UTP was the standard cable used with Ethernet 10Base-T.
Cat 5 UTP
Category 5 UTP is rated to carry Ethernet up to 100Mbit/s and ATM up to 155Mbit/s.
Cat 5 UTP was the standard cable used with Ethernet 100Base-TX.
Cat 5e UTP
Category 5e UTP is an enhanced version of Cat 5 UTP.
Cat 5e UTP is rated to carry data up to 1000Mbit/s.
Cat 5e UTP is the standard cable used with Ethernet 1000Base-T.
Cat 5e can also be used to extend the distance of 100Base-TX cable runs up to 350 meters.
Cat 6 UTP
Category 6 UTP is very similar to Cat 5 UTP, except that it is designed and manufactured to even stricter standards.
UTP Termination
Two-pair (four-wire) UTP used for telephone use is normally terminated in an RJ-11 connector.
Four-pair (eight-wire) UTP used for data use is normally terminated in an RJ-45 connector.

- Cat 3
Cat 3, short for Category 3, is a UTP (Unshielded Twisted Pair) cable designed to carry voice and data up to 10 Mbps (mega bits per second), with possible transmission frequencies up to 16 MHz. Cat 3 cable is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance (EIA) [...]...
- Cat 5
Cat 5, short for Category 5, is the current accepted industry standard for network and telephone wiring. Cat 5 is an unshielded twisted pair type cable exclusively designed for high signal integrity. The cable consists of four pairs of 24-guage twisted copper pairs terminating in an RJ-45 jack. If a wire is certified as Category [...]...
- Ethernet Cable Pinout
Ethernet cable connects a network interface card (NIC) with a hub or Ethernet switch. Ethernet cables can be purchased from a computer store. They come in two categories, flat and braided. The flat or solid cable is used when there is a need for a longer cable run. However, it is not flexible. Thus, its [...]...
- Cat 6
Cat 6 (Category 6) is a cable standard used mainly for Ethernet computer networking, security systems, and telephone services. Cat 6 cable is backward compatible with the Cat 5, Cat 5E, and Cat 3 cable standards. Category 6 cable is capable of transmitting voice and data up to 155 Mbps (mega bits per second), with [...]...
- Ethernet
Ethernet is the most common LAN (Local Area Network) technology in use today. Xerox developed Ethernet in the 1970s, and became popular after Digital Equipment Corporation and Intel joined Xerox in developing the Ethernet standard in 1980. Ethernet was officially accepted as IEEE standard 802.3 in 1985. The term “Ethernet” is now used to refer [...]...
why the hell , the unshielded twisted pair called so, as it is already shielded or insulated
hari om:
“Shielding”, in this context, refers to shielding against RF interference. Insulation doesn’t do that.

I want to know what are the virtue of UTP…
Dear Mr.Samuel Boateng
you inverted the UTP pinout assignment, since the T568A standard is WG,G,WO,Blue,WBlue,O,WBrown,Brown but the T568B standard is WO,O,WG,Blue,WBlue,G,WBrown,Brown
what is the main function of the unshilded twisted pair(UTP)
