CAT-5/5e

[Also known as Category 5/5e Cable] A twisted pair cable type designed for high signal integrity. Many such cables are unshielded but some are shielded.

Category 5 has been superseded by the Category 5e specification. This type of cable is often used in structured cabling for computer networks such as Ethernet, and is also used to carry many other signals such as KVM, A/V and USB.

Category 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs (this latter form of interference is called crosstalk). It is most commonly used for Ethernet networks and extender systems.

CAT- 5 cable typically has three twists per inch of each twisted pair of 24 gauge copper wires within the cable.
