Explanation
CAT (Category) ratings - such as CAT3, CAT5, CAT5e, CAT6, and CAT7 - are standards defined by the Telecommunications Industry Association (TIA) for Twisted Pair copper cables. These cables consist of pairs of copper wires twisted together to reduce electromagnetic interference (EMI) and crosstalk. CAT3 supports up to 10 Mbps (used in older telephone and 10BASE-T Ethernet), while CAT5 supports up to 100 Mbps (Fast Ethernet). Coaxial cables use a different construction with a central conductor surrounded by shielding. Fiber optic cables carry light signals, not electrical signals, and have no CAT ratings.
