Patch cables are often used for short distances in offices and wiring closets. Ethernet patch cable can link a computer to a network hub, router or Ethernet switch, which is useful for constructing home computer networks.
The standard for Category 6A (augmented Category 6) is ANSI/TIA-568-C.1, defined by the Telecommunications Industry Association (TIA) for enhanced performance standards for twisted pair cable systems. It was defined in 2009. Cat 6A performance is defined for frequencies up to 500 MHz—twice that of Cat 6. Cat 6A also has an improved alien crosstalk specification as compared to Cat 6, which picks up high levels of alien noise at high frequencies.
