This part of IEC 60728 is applicable to in-building optical transmission systems for broadcast signal transmission that consist of optical transmitter, 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 interface (BNI) and home network interface (HNI) in order to assess the system performance and its performance limits. This document is also applicable to broadcast signal transmission using a telecommunication network if it satisfies the requirements of optical section 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 xPON 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 network, thus, it does not include IP transport technologies, such as IP Multicast and associate protocols. This standard specifies the required system performance of all-optical building networks in order to connect with FTTH networks which are defined by IEC60728-113 and IEC60728-13-1. Use of In-building optical networks is very effective for saving cost (installation and maintenance) and enabling future network up-grades, especially in huge apartment buildings. In this document, the optical wavelengths and electrical frequency bands listed in Table 1 – and Table 2 – are considered to be used. [Table 1 and Table 2]<\/p>\n
