ISO/IEC 11801 proposed channel utilizing twisted-pair cabling rated to 500MHz. Corresponds closely to the TIA/EIA Category 6A cabling standard, but there are some differences in some internal performance requirements. (2) IP addresses used for experimental purposes that have a range of numbers from 240 through 255 in the first octet.

The process of separating an unbuffered optical fiber by scoring the outside and pulling off the end. Cleaving creates a controlled fracture of the glass for the purpose of obtaining a fiber end that is flat, smooth, and perpendicular to the fiber axis. This is done prior to splicing or terminating the fiber.

An enclosed space for housing telecommunications and networking equipment, cable terminations, and crossconnect cabling. It contains the horizontal cross-connect where the backbone cable cross-connects with the horizontal cable. Called a telecommunications room by the TIA/EIA standards; sometimes referred to as a wiring closet.

The first true protective layer of an optical fiber. The plastic-like coating surrounds the glass cladding of a fiber and put on a fiber immediately after the fiber is drawn to protect it from the environment. Do not confuse the coating with the buffer.

Also called coax. Coaxial cable was invented in 1929 and was in common use by the phone company by the 1940s. Today it is commonly used for cable TV and by older Ethernet; twisted-pair cabling has become the desirable way to install Ethernet networks. It is called coaxial because it has a single conductor surrounded by insulation and then a layer of shielding (which is also a conductor) so the two conductors share a single axis; hence
