信息技术.用户建筑群的通用布缆

[中文适用范围]： ISO/IEC 11801 指定了在场所内使用的通用布线，场所可能包括校园内的单个或多个建筑物。 它涵盖平衡布线和光纤布线。 ISO/IEC 11801 针对可分布电信服务的最大距离为 2 000 m 的场所进行了优化。 本国际标准的原则可适用于较大的装置。 该标准定义的布线支持多种服务，包括语音、数据、文本、图像和视频。 本国际标准直接或通过参考规定了：a）通用布线的结构和最低配置，b）电信插座（TO）的接口，c）单个布线链路和通道的性能要求，d）实施要求和选项，e ) 本标准规定的最大距离所需的布线组件的性能要求， f) 一致性要求和验证程序。 安全（电气安全和防护、防火等）和电磁兼容性（EMC）要求不在本国际标准的范围内，并由其他标准和法规涵盖。 然而，本标准提供的信息可能会有所帮助。 ISO/IEC 11801 考虑了附录 F 中列出的应用标准中指定的要求。 它在适当的情况下引用了组件和测试方法的可用国际标准。 [外文原描述]： Within customer premises, the importance of the cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power. As with other utilities, interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect installation, poor administration or inadequate support can threaten an organisation's effectiveness. Historically, the cabling within premises comprised both application specific and multipurpose networks. The original edition of this standard enabled a controlled migration to generic cabling and the reduction in the use of application-specific cabling. This second edition of ISO/IEC 11801 has been developed to reflect the increased demands and opportunities which have arisen since - and are partly the result of - publication of the first edition in 1995. The contents of the corrigendas of September 2002 and December 2002 have been included in this copy.
