Cat6 / Cat6A Cable
Twisted-pair copper cabling rated for gigabit (Cat6) or 10-gigabit (Cat6A) Ethernet.
What is Cat6 / Cat6A Cable?
Cat6 supports 1 Gbps to 100m and 10 Gbps to ~55m. Cat6A supports 10 Gbps to the full 100m and is the EIG PRO standard for new commercial backbones, IDF cross-connects, and high-PoE devices. Plenum-rated (CMP) jacket is required in air-handling spaces. In a coordinated design, Cat6 / Cat6A Cable is selected by required performance, environment, pathway capacity, listed use, compatibility, and the project specification. Product names alone do not establish compliance: the complete channel, supports, terminations, grounding where applicable, and installation workmanship all affect the result. Submittals should identify the exact product and rating before procurement, while field installation should follow the approved details and manufacturer instructions. During closeout, the contractor should verify locations, labels, terminations, and test requirements, then record deviations on as-built documents. Owners should retain product data and results with the room, rack, port, or device schedule. This approach makes Cat6 / Cat6A Cable maintainable after turnover and prevents an undocumented component choice from becoming a future troubleshooting problem.
