Cable networks for television signals, sound signals and interactive services - Part 13-1: Bandwidth expansion for broadcast signal over FTTH system (IEC 60728-13-1:2017 + COR1:2017)

The purpose of this part of IEC 60728 is the precise description of an FTTH (fibre to the home)
system for expanding broadband broadcast signal transmission from CATV services only,
towards CATV plus broadcast satellite (BS) plus communication satellite (CS) services,
additionally to other various signals such as data services.
The scope is limited to the RF signal transmission over FTTH systems.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 13-1. del: Razširitev pasovne širine za radiodifuzijske signale po optičnih vlaknih do doma (FTTH) (IEC 60728-13-1:2017 + COR1:2017)

Namen tega dela standarda IEC 60728 je natančen opis sistema FTTH (sistem optičnih vlaken do doma) za razširitev pasovne širine za prenos signalov iz storitev CATV tudi na CATV plus radiodifuzne satelitske (BS) in komunikacijske satelitske (CS) storitve ter na druge različne signale, kot so podatkovne storitve.
Področje uporabe je omejeno na radiofrekvenčni prenos signalov po sistemih FTTH.

Part 13-1: Bandwidth expansion for broadcast signal over FTTH system

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60728-13-1 has been prepared by technical area 5: Cable networks
for television signals, sound signals and interactive services, of IEC technical committee 100:
Audio, video and multimedia systems and equipment.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition.
• Transmission frequency was expanded in order to achieve satellite signal for 4 K video
service. The transmission frequency over FTTH would be 3 300 MHz.
• High signal modulation case like 16 APSK and 32 APSK was added in order to correspond to
transmission for 4 K video service.

INTRODUCTION
Standards and deliverables of the IEC 60728 series deal with cable networks including
equipment and associated methods of measurement for headend reception, processing and
distribution of television and sound signals and for processing, interfacing and transmitting all
kinds of data signals for interactive services using all applicable transmission media. These
signals are typically transmitted in networks by frequency-multiplexing techniques.
This includes for instance
• regional and local broadband cable networks,
• extended satellite and terrestrial television distribution systems,
• individual satellite and terrestrial television receiving systems,
and all kinds of equipment, systems and installations used in such cable networks, distribution
and receiving systems.
