The Telecommunications Industry Association (TIA) of Arlington, VA announced today that the Category 6 standard for telecom cabling has been approved for publication as TIA/EIA-568-B.2-1.
The new Category 6 standard specifies requirements for 100-ohm balanced twisted-pair cables, connecting hardware, patch cords, channels and permanent links, and provides test procedures for laboratory and field performance verification over the frequency range of 1 to 250 MHz.
TIA says that because Category 6 supports positive power sum attenuation to crosstalk (PSACR) margins up to 200 MHz, this new cabling system offers double the bandwidth of Category 5e cabling and vastly improved signal-to-noise margins. The Category 6 standard also includes cable and connecting hardware balance recommendations for improved electromagnetic compatibility performance.
“Category 6 facilitates data throughput previously unachievable over balanced twisted-pair cabling,” says Bob Jensen, TIA TR-42 Committee Chair. “TIA and the ATM Forum have already published gigabit applications standards to operate over Category 6 cabling. We anticipate applications groups to begin development of protocols supporting even higher throughput over Category 6 cabling.”
Category 6 cabling recognizes advances in cabling technology and is designed to be backward compatible with Categories 3, 5 and 5e. This ensures that any applications that operate on lower category cabling will be fully supported by Category 6 cabling. When different category components are mixed with Category 6 components, the resultant cabling will satisfy the category transmission requirements of the lower performing component.
To ensure generic cabling system performance, Category 6 component requirements are specified to be interoperable when products from different manufacturers are mated.
