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