Copper VDV Tools

摘要

Enthusiasm about high bandwidth capabilities of fiber optic cable, and speeds with which fiber transmits data and video, often overshadows the fact that most end-user residential connections still are made with copper cable. Also, most local-area networks (LANs) in business applications contain twisted-pair copper wiring for conventional telephone service, data transmission, computer networks and to operate security and fire-alarm systems and intelligent building controls. Coaxial cable supports audio and video connectivity.
