1 Scope
This part of IEC 60728 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
