标准摘要
[中文适用范围]: IEC 60728的本部分适用于广播信号传输的光传输系统,该系统由前端设备@光传输线路@内部布线和系统插座组成。该系统主要用于使用模拟和/或数字传输技术的电视和声音信号。本标准规定了具有系统出口的光分配系统的基本系统参数和测量方法,以评估系统性能及其性能极限。 IEC 60728 这部分的目的是描述用于广播信号传输的 FTTH(光纤到户)网络的系统规范。如果满足本标准的光学部分,本标准也适用于使用电信网络的广播信号传输。该标准描述了 FTTH@ 上广播和窄播(广播的有限区域分布)信号的 RF 传输,并引入了 xPON 系统作为物理层媒体。物理层的详细描述超出了本标准的范围。范围仅限于 FTTH@ 上的射频信号传输,因此不包括 IP 传输技术@,例如 IP 组播和相关协议。应参考第 7 条和附件 D 中涉及的电信系统和广播系统之间的一些干扰描述来进行详细解释。附件A描述了基于本标准的实际服务系统的设计考虑。附件 B 概述了适用于广播信号传输的光传输系统。 [外文原描述]: IEC 60728-13:2010 specifies the basic system parameters and methods of measurement for optical distribution system having a system outlet in order to assess the system performance and its performance limits. It describes the system specification of FTTH (fibre to the home) network for broadcast signal transmission. It is also applicable to the broadcast signal transmission using telecommunication network if it satisfies the optical portion of this standard. It describes RF transmission for broadcast and narrowcast (limited area distribution of broadcast) signals over FTTH, and introduces xPON system as a physical layer media. The contents of the corrigendum of August 2010 have been included in this copy.
