EN 60728-14:2014

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

IEC 60728-14:2014 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.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 14: Systèmes de transmission optique appliquant la technologie RFoG

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.
