Category 6 cable cat 6 is a standardized twisted pair cable for ethernet and other network physical layers that is backward compatible with the category 5 5e and category 3 cable standards.
Cat 6 supports 10 gigabit ethernet only up to 164 feet of cable length.
Belden offers several category 6 performance levels including our 3600 series with premium performance offering significant headroom and our 2400 cat 6 enhanced system cable.
So cat 6 is faster than cat 5.
Draft specification ansi tia eia 568 b 2 10 specifies cable systems called augmented category 6 or more frequently as category 6a that operate at frequencies up to 500 mhz and will provide up to 10.
The cable contains 4 twisted pairs individually shielded cabled double.
N compliant to tia eia 568 b 2 1 category 6 cable specifications n supports ultrahigh speed data networks such as gigabit ethernet.
The category 6 augmented cable standard or cat 6a was created to further improve the performance of cat 6 ethernet cables using cat 6a enables 10 gigabit ethernet data rates over a single cable run up to 328 feet.
The cable standard specifies performance of up to 250 mhz compared to 100 mhz for cat 5 and cat 5e.
More than cat 5 offer 1gb data speed where cat 6 offers 10gb data speed.
We recommend that the full range of powercat 6 products are used in a system to maximise cabling performance providing extended frequency response and enhanced bandwidth.
Every level exceeds tia 568 c 2 s performance and are produced with belden s superior quality.
