CAT 5

Cat 5, is a twisted pair cable for computer networks. Cat 5 is also used to carry other signals such as telephony and video. These cables are commonly connected using punch-down blocks and modular connectors. Most Category 5 cables are unshielded, relying on the balanced line twisted pair design and differential signaling for noise rejection.

The cable is available in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking. Patch cables are stranded. Permanent wiring used in structured cabling is solid-core.
