Provides building owners, managers, architects, designers, manufacturers, installers, maintainers and users with requirements to ensure compatibility with equipment and services and to ensure performance of infrastructure to meet present and foreseeable future requirements. This Interim Standard is identical with and has been reproduced from ISO/IEC JTC/1SC25 N 780:2002.

International Standard ISO/IEC 11801 specifies generic cabling for use within premises, which may comprise single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling.This International Standard is optimised for premises in which the maximum distance over which telecommunications services can be distributed is 2 000 metres. The principles of this International Standard may be applied to larger installations.Cabling defined by this International Standard supports a wide range of services including voice, data, text, image and video.T0his International Standard specifies directly or via reference the: a) structure and minimum configuration for generic cabling, b) interfaces at the telecommunications outlet (TO), c) performance requirements for individual cabling links and channels d) implementation requirements and options, e) performance requirements for cabling components required for the maximum distances specified in this standard, f) conformance requirements and verification procedures.Safety (electrical safety and protection, fire, etc.) and Electromagnetic Compatibility (EMC) requirements are outside the scope of this International Standard, and are covered by other standards and by regulations. However information in this International Standard may be of assistance.
