ESTANDAR 568A Y 568B PDF

Generally increasing category numbers correspond with a cable system suitable for higher rates of data transmission. Developers hope the standards will provide a lifespan for commercial cabling systems in excess of ten years. The development of high-performance twisted pair cabling and the popularization of fiber optic cables also drove significant change in the standards. The demands placed upon commercial wiring systems increased dramatically over this period due to the adoption of personal computers and data communication networks and advances in those technologies. At the work area, equipment is connected by patch cords to horizontal cabling terminated at jackpoints.
