NEMA - ANSI/NEMA WC 66
Standard for Category 6 and 6A, 100 Ohm, Individually Unshielded Twisted Pairs, Indoor Cables (With or Without an Overall Shield) for Use in LAN Communication Wiring Systems
|Publication Date:||1 January 2019|
This Standard covers mechanical, electrical, and flammability requirements for thermoplastic insulated and jacketed, copper conductor, individually unshielded twisted pairs, with or without overall shield intended for use as horizontal cables, backbone cables, or in the manufacture of patch cords. Depending upon the application and system requirements, this Standard provides choices for materials and flammability ratings.
This Standard covers the minimum performance requirements for cables up to four pairs, with transmission characteristics specified up to 250 MHz for Category 6 cables and up to 500 MHz for Category 6A cables.
These Category cables are intended for voice, text, data, video, and image transmission as well as low voltage power supply (POE & POE+). The cables are categorized by electrical transmission characteristics based on existing system requirements and projected application needs determined by IEEE 802.3.
The cables included are intended to conform to the cabling system architecture and design, as specified in ANSI/TIA/568-C.2. Applicable definitions, test methods, and performance requirements are included.
For additional Categories, see companion ICEA Standards S-90-661 for Categories 3, 5, 5e, and S-118-746 for Category 8.
The products covered in this Standard should conform to the requirements of Part 68 of the FCC rules and regulations.
The performance requirements contained in this document are for cables as manufactured. Link and channel requirements are beyond the scope of this document.
