标准范围

IEC 60728-115:2022适用于由光发射机、光放大器、分路器、V-ONU等组成的用于广播信号传输的室内光传输系统。这些系统主要用于使用数字传输技术的电视和声音信号。本文件规定了建筑物网络接口（BNI）和家庭网络接口（HNI）之间的建筑物内光分配系统的基本系统参数和测量方法，以评估系统的性能及其性能限制。如果满足本文件的光学部分的要求，本文件也适用于使用电信网络的广播信号传输。本文档描述了FTTH网络上全数字化广播和窄播（广播的有限区域分布）信号的RF传输，并介绍了X-PON系统作为物理层介质。物理层的详细描述超出了本文档的范围。范围仅限于光网络上的RF信号传输；因此，它不包括IP传输技术，诸如IP多播和相关协议。本文件规定了全光建筑网络所需的系统性能，以便与FTTH网络建立连接，这些网络由IEC 60728-113和IEC 60728-13-1定义。使用建筑内光网络对于节省成本（安装和维护）和实现未来的网络升级非常有效，尤其是在巨大的公寓楼中。

IEC 60728-115:2022 is applicable to in-building optical transmission systems for broadcast signal transmission that consist of optical transmitters, optical amplifiers, splitters, V-ONUs, etc. These systems are primarily intended for television and sound signals using digital transmission technology. This document specifies the basic system parameters and methods of measurement for in-building optical distribution systems between building network interfaces (BNI) and home network interfaces (HNI) in order to assess the system's performance and its performance limits.
This document is also applicable to broadcast signal transmission using a telecommunication network if it satisfies the requirements of the optical portion of this document. This document describes RF transmission for fully digitalized broadcast and narrowcast (limited area distribution of broadcast) signals over an FTTH network and introduces the X-PON system as a physical layer media. The detailed description of the physical layer is out of the scope of this document. The scope is limited to RF signal transmission over optical networks; thus, it does not include IP transport technologies, such as IP multicast and associated protocols.
This document specifies the required system performance of all-optical building networks in order to establish connections with FTTH networks, which are defined by IEC 60728-113 and IEC 60728-13-1. Use of in-building optical networks is very effective for saving costs (installation and maintenance) and enabling future network upgrades, especially in huge apartment buildings.
