<P> Category 6 cable, commonly referred to as 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 . </P> <P> Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise . The cable standard specifies performance of up to 250 MHz . </P> <P> Whereas Category 6 cable has a reduced maximum length when used for 10GBASE - T, Category 6A cable (or Augmented Category 6) is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE - T to be run for the same 100 meter maximum distance as previous Ethernet variants . </P>

Cat 6 utp is recommended for use in
