Category 5 cable, commonly referred to as cat 5, is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as ethernet. The cable standard provides performance of up to 100 MHz and is suitable for fast ethernet and gigabit ethernet. Cat 5 is also used to carry other signals such as video. Most category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection. This type of cable is used in structured cabling for computer networks such as ethernet over twisted pair.
Category cable will support 10/100 ethernet. Computers hooked up to LAN (local area network) are connected using category 5 cable. Home networks, security cameras, telephones and even HDMI devices can use category 5 to transmit their data.Cat 5 is a nickname for cable with four wire pairs that each meet the category 5 specification for data communication. The specification defines the conductor size, insulation quality and wire twists, plus a multitude of performance characteristics.
