提供用于确定电视信号、声音信号和交互服务的有线网络中使用的光传输系统的总体性能的指南和程序。它基于IEC 60728-6中定义的光学设备要求，应与本标准一起使用。提供的信息旨在帮助现场工程师和网络规划师（系统设计师）规划和设计光学系统。虽然这方面的内容没有标准中那么密集，但需要有关有线网络系统参数的基本知识。

provides guidelines and procedures for determining the overall performance of optical transmissions systems used in cable networks for television signals, sound signals and interactive services. It is based on the requirements for optical equipment defined in IEC 60728-6 and should be used together with this standard. The information provided is meant to help field engineers and network planners (system designers) in planning and designing optical systems. Though this content is less dense than in a standard, basic knowledge about system parameters of cable networks is needed.
