IEC 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 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. It describes the system specification of FTTH (fibre to the home) network for broadcast signal transmission. It is also applicable to the broadcast signal transmission using telecommunication network if it satisfies the optical portion of this standard. It 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 contents of the corrigendum of August 2010 have been included in this copy.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 13: Systèmes optiques pour la transmission de signaux de diffusion

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.
