Cable networks for television signals, sound signals and interactive services - Part 14: Optical transmission systems using RFoG technology (IEC 60728-14:2014)

EN IEC 60728-14 describes the system and equipment specification of FTTH/FTTB (fibre to the home/fibre to the building) networks where information is transmitted in both, forward and return path directions using RF subcarrier multiplexing technology, and where the return path transmission uses additionally time division multiple access technique imposed by the transmission of the return path signals using a TDMA (e.g. TDMA mode of DOCSIS) protocol. Such systems are called RF over Glass (RFoG) and consist of an RFoG optical network unit (R-ONU), an optical distribution network based on xPON structure, and an RFoG optical return path receiver. This standard specifies the basic system parameters and methods of measurement for RFoG systems in order to assess the system performance and its performance limits. The detailed description of physical layer is out of the scope of this standard and it does not include IP transport technologies.

Réseaux de distribution par câbles destinés aux signaux de télévision, de radiodiffusion sonore et aux service interactifs - Partie 14: Systèmes de transmission optique appliquant la technologie RFoG (CIE 60728-14:2014)

L'IEC 60728-14:2014 décrit les spécifications système et matériel des réseaux FTTH/FTTB (fibre optique jusqu'au domicile/fibre optique jusqu'à l'immeuble) où l'information est transmise à la fois dans le sens de voie directe et dans le sens de voie de retour, en utilisant la technologie de multiplexage par sous-porteuse RF, et où la transmission en voie de retour utilise de plus la technique d'accès multiple par répartition temporelle imposée par la transmission des signaux de voie de retour utilisant un protocole AMRT (par exemple, mode AMRT de DOCSIS). Ces systèmes sont appelés systèmes à radiofréquence sur fibre de verre (RFoG) et se composent d'une unité de réseau optique RFoG (R-ONU), d'un réseau de distribution optique basé sur la structure xPON et d'un récepteur de voie de retour optique RFoG. La présente norme spécifie les paramètres de base du système, ainsi que les méthodes de mesure pour les systèmes RFoG, pour évaluer tant les performances du système que ses limites.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 14. del: Optični prenosni sistemi s tehnologijo RFoG (IEC 60728-14:2014)

Standard EN IEC 60728-14 opisuje specifikacijo sistema in opreme za omrežja FTTH/FTTB (optična vlakna do doma/optična vlakna do stavbe), kjer se informacije prek tehnologije multipleksiranja podnosilca radijskih frekvenc prenašajo v obeh smereh, po naprejšnji in povratni poti. Ob tem prenos po povratni poti uporablja dodatno tehniko več dostopov z delitvijo časa, ki jo omogoča prenos signalov po povratni poti prek protokola TDMA (npr. način TDMA za DOCSIS). Tovrstni sistemi so imenovani prenosni sistemi radijskih frekvenc prek optičnih vlaken (RFoG), ki predstavljajo optično distribucijsko omrežje, temelječe na strukturi xPON in sprejemniku optične povratne poti RFoG. Ta standard določa osnovne sistemske parametre in metode za merjenje sistemov RFoG z namenom ocenjevanja učinkovitosti sistema in njegovih omejitev. Standard ne zajema podrobnega opisa fizične plasti in tehnologij prenosa IP.

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.
