The purpose of this Technical Report is to be a first guideline for those considering to install a high bandwidth (high bit-rate) FTTx-network. After studying the Technical Report operators, communities, energy companies, installers and others will understand the necessary steps to take to plan and install FTTx-networks with high quality and cost effectiveness, and to secure a uniform structure and a high quality level on such networks.
This part of IEC 60728 is applicable to optical transmission system for broadcast signaltransmission that consists of a head-end equipment, optical transmission lines, in-housewirings and a system outlet. The system is primarily intended for television and sound signalsusing analogue and/or digital transmission technology. This standard specifies the basicsystem parameters and methods of measurement for optical distribution system having asystem outlet in order to assess the system performance and its performance limits.The purpose of this part of IEC 60728 is to describe the system specification of FTTH (fibre tothe home) network for broadcast signal transmission. This standard is also applicable to thebroadcast signal transmission using telecommunication network if it satisfies the opticalportion of this standard. This standard describes RF transmission for broadcast andnarrowcast (limited area distribution of broadcast) signals over FTTH, and introduces xPONsystem as a physical layer media. The detailed description of physical layer is out of thescope of this standard. The scope is limited to RF signal transmission over FTTH, thus, itdoes not include IP transport technologies, such as IP Multicast and associate protocols.Some interference descriptions between telecommunication system and broadcast systemaddressed in Clause 7 and Annex D should be referred to for detailed explanations. Annex Adescribes actual service systems with design consideration based on this standard. Annex Bgives an overview of the optical transmission systems applicable for broadcast signaltransmission.
