Applications for Category 6 cables include voice, multimedia, and data transmission as well as ATM networks. The conductors are made of 100% copper and are unshielded, and the cable features bend protection. The jacket is made from halogen-free materials and is highly flame-resistant. The UTP cable consists of a plastic sheath that houses the unshielded, twisted pairs of wires. Due to the absence of shielding, UTP cables have a small outer diameter, making them easy to handle and install.
