Category 3 cable

|
Category 3 cable, commonly known as Cat-3, is an unshielded twisted pair (UTP) cable designed to reliably carry data up to 10 Mbit/s. It is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance and the Telecommunications Industry Association. It was a popular cabling format among computer network administrators in the early 1990s, but has since been almost entirely replaced by the very similar Cat-5 standard, which offers higher top speeds.
