Data cable systems are high-density, rack-to-rack connection systems for data and telecommunication equipment. Even with the advancements of wireless technology, many computers, routers, switches and storage area networks today still rely on data cables as a physical medium to create connections as well as exchange and transfer data.

A data cable system is a cabling system that allows multiple network devices in different areas to communicate with one another, with the use of data network cables. These data network cables include CAT 5e, CAT 6, CAT 6a, twisted pair cables, and fibre optic cables.
