SIST EN 60728-13:2010

Cable networks for television signals, sound signals and interactive services - Part 13: Optical systems for broadcast signal transmissions (IEC 60728-13:2010 )

This part of IEC 60728 is applicable to optical transmission system for broadcast signal transmission that consists of a head-end equipment, optical transmission lines, in-house wirings and a system outlet. The system is primarily intended for television and sound signals using analogue and/or digital transmission technology. This standard specifies the basic system parameters and methods of measurement for optical distribution system having a system 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 to the home) network for broadcast signal transmission. This standard is also applicable to the broadcast signal transmission using telecommunication network if it satisfies the optical portion of this standard. This standard describes RF transmission for broadcast and narrowcast (limited area distribution of broadcast) signals over FTTH, and introduces xPON system as a physical layer media. The detailed description of physical layer is out of the scope of this standard. The scope is limited to RF signal transmission over FTTH, thus, it does not include IP transport technologies, such as IP Multicast and associate protocols. Some interference descriptions between telecommunication system and broadcast system addressed in Clause 7 and Annex D should be referred to for detailed explanations. Annex A describes actual service systems with design consideration based on this standard. Annex B gives an overview of the optical transmission systems applicable for broadcast signal transmission.

Réseaux de distribution par câbles destinés aux signaux de télévision, de radiodiffusion sonore et aux services interactifs - Partie 13 : Systèmes optiques pour transmission de signaux de radiodiffusions (CEI 60728-13:2010 )

L'IEC 60728-13:2010 s'applique à un système de transmission optique pour la transmission de signaux de diffusion, qui se compose de l'équipement de la tête de réseau, des lignes de transmission optique, des câblages internes et d'une prise d'abonné. Le système est principalement prévu pour la télévision et les signaux sonores qui utilisent une technologie de transmission analogique et/ou numérique. La présente norme spécifie les paramètres de base du système et les méthodes de mesure du système de distribution optique équipé d'une prise d'abonné, afin d'évaluer les performances du système et ses limites de performances.
L'IEC 60728-13:2010 a pour objet la description de la spécification système du réseau de desserte par fibre de l'abonné (DFA) pour la transmission de signaux de diffusion. La présente norme s'applique également à la transmission des signaux de diffusion qui utilisent un réseau de télécommunication, si celui-ci respecte la partie de la présente norme consacrée à l'optique. La présente norme décrit la transmission de signaux radioélectriques en tant que signaux de diffusion générale et de diffusion ciblée (distribution de la diffusion dans une zone limitée) sur le réseau de desserte par fibre de l'abonné et introduit le système xPON comme support de la couche physique. La description précise de la couche physique ne fait pas partie du domaine d'application de la présente norme. Le domaine d'application se limitant à la transmission des signaux RF sur les réseaux de desserte par fibre de l'abonné, les technologies de transport par protocole Internet (IP), comme la multidiffusion IP et les protocoles associés, ne sont donc pas incluses. Certaines descriptions des interférences entre le système de télécommunication et le système de diffusion sont couvertes par l'Article 7, et il convient de se référer à l'Annexe D pour des explications détaillées. L'Annexe A présente des considérations sur les systèmes de services réels et la conception d'après la présente norme. L'Annexe B donne une vue d'ensemble des systèmes de transmission optique applicables à la transmission de signaux de diffusion.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 13. del: Optični sistemi za razpršeno oddajanje signalov (IEC 60728-13:2010)

Ta del IEC 60728 velja za optične oddajne sisteme za razpršeno oddajanje signalov, ki so sestavljeni iz opreme glavne razdelilne postaje, optičnih oddajnih linij, internega ožičenja in sistemskih izhodov. Sistem je prvotno namenjen za televizijske in zvočne signale, ki uporabljajo analogno in/ali digitalno tehnologijo oddajanja. Ta standard določa osnovne sistemske parametre in metode merjenja za optične razdelitvene sisteme, ki imajo sistemski izhod, za ocenitev delovanja sistema in njegovih mej delovanja. Namen tega dela IEC 60728 je, da opiše sistemske tehnične zahteve FTTH (vlakno do doma) omrežja za razpršeno oddajanje signalov. Ta standard prav tako velja za razpršeno oddajanje signalov, kjer se uporablja telekomunikacijsko omrežje, če je primerno za optični del tega standarda. Ta standard opisuje RF oddajanje za razpršene in ozko usmerjene (omejeno razdelitveno območje razpršitve) signale skozi FTTH in uvaja xPON sistem kot fizično plast medija. Natančni opis fizične plasti ni zajet v tem standardu.  Področje je omejeno na oddajane RF signalov skozi FTTH in tako ne vsebuje IP tehnologij prenosa, kot je tehnologija IP Multicast in z njo povezani protokoli. Nekateri opisi motenj med telekomunikacijskim sistemom in oddajnim sistemom, navedeni v Klavzuli 7 in Dodatku D, se lahko sklicujejo na podrobne pojasnitve. Dodatek A opisuje dejanske servisne sisteme, katerih načrtovanje je osnovano na tem standardu. Dodatek B podaja pregled optičnih oddajnih sistemov, ki se uporabljajo za razpršeno oddajanje signalov.

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.

INTRODUCTION
Standards of the IEC 60728 series deal with cable networks including equipment and
associated methods of measurement for headend reception, processing and distribution of
television signals, sound signals and their associated data signals and for processing,
interfacing and transmitting all kinds of signals for interactive services using all applicable
transmission media.
This includes
1
• CATV0-networks;
• MATV-networks and SMATV-networks;
• individual receiving networks;
and all kinds of equipment, systems and installations installed in such networks.
