This document summarizes the specifications and categories of unshielded twisted pair (UTP) cable. It describes the EIA/TIA 568 standard for UTP cables and the testing parameters for categories 1-7, including minimum frequency, attenuation, NEXT, ELFEXT, and more. It also explains the common cable categories and their typical data transmission speeds as well as comparisons between UTP and shielded twisted pair cables.
