Category 3 Twisted Pair Cable

Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility.

Category 3 twisted pair cable.

A category 3 cable cat 3 cable is a type of unshielded twisted pair utp cable that is used for voice and data communications in computer and telecommunication networks. White 550mhz cmr box. According to ieee 70 of new installs in 2004 were cat 6. Although designed to reliably carry data up to 10 mbit s modern data networks run at much higher speeds and cat 5e or better cable is generally used for new inst.

Yellow 24 4 unshielded twist pair cable with ft4 rated. White 24 3 unshielded twist pair cable. Cat6 riser 1 000 ft. Blue 24 4 solid cu cat5e cmr riser data cable.

Both cat 3 and cat 5 cables are comprised of four twisted pair for a total of eight 24 gauge copper wires. Compared to a single conductor or an untwisted balanced pair a twisted pair reduces electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves rejection of external electromagnetic interference. Both cable standards are unshielded and both have an outer sheath stamped as certified cat 3 or cat 5. Cat3 cable is an unshielded ethernet cable that relies on copper conductors to transmit data and power.

It was invented by alexander graham bell. It purposely defines the standards for cables such as 100 ohms and shielded twisted pair cables and optical fiber cables. The cat 6 specification published in 2002 the same time as iso category 7 class f improves on cat 5e in terms of near end crosstalk balance and bandwidth. Card monster category 3 twisted pair wire 6 conductor 24 awg 3 twisted pairs ul listed recommended for use with multiple phone lines or networking computers 100 ft carded.

It is part of a family of standards defined jointly by the electronic industries alliance and the telecommunications industry association and published in tia eia 568 b. Tygerwire category 5 1000 ft. Digiwave category 3 1000 ft. Furthermore some of the twisted pair cabling standards that normalizes the designing and managing of cabling system are.

It is a standard that is used in commercial buildings and cabling systems that support data networks voice and video. These cables were the standard for ethernet cables in the 1990 s and are capable of handling up to 10 mbps. Monster cable category 3 twisted pair wire 6 conductor 3 twisted pair 100 ft.

Category 7 class f iso iec published in 2002 is a fully shielded system. Cat 3 cabling is near end crosstalk certified for only a 16 mhz signal while cat 5 cable must pass a 100 mhz test.
