Channels implemented using category 6 2002 components will support 10GBase-T provided they meet the additional requirements specified in ISO/IEC TR-24750. Such support may be limited to channels shorter than 100 m. Class E A or better is recommended for new installations. bincluding support for remote power feeding defined by IEEE 802.3af: 2003.
