The cable type and connector used to attach a television set to a catv network is a coaxial cable with a screw-on f-type connector. Although catv networks typically use fiber-optic cables and st connectors for outdoor connections, they do not use fiber for internal connections to television sets. Coaxial cables with bnc connectors are most commonly used for thin ethernet lans, not catv network connections. Twisted-pair cables and rj-45 connectors are used for ethernet lans and telephone networks, but not catv networks. AUI cables and vampire tap connectors are used for thick ethernet networks.
