IEC 60728-13-1:2017

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 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.
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.
The contents of the corrigendum of September 2017 have been included in this copy.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 13-1: Extension de la largeur de bande pour les signaux de diffusion sur un système DFA

L'IEC 60728-13-1:2017 a pour objet la description précise d'un système DFA (desserte par fibre de l'abonné) pour étendre la transmission des signaux de diffusion à large bande depuis les services CATV uniquement, vers les services CATV, les services de diffusion par satellite (BS), les services de communication par satellite (CS), et d'autres signaux différents tels que les services de données.
Le domaine d'application est limité à la transmission des signaux RF sur les systèmes DFA.
L'IEC 60728-13-1:2017 inclut les modifications techniques majeures suivantes par rapport à l'édition précédente.
- La fréquence de transmission a été étendue afin d'obtenir un signal par satellite pour le service de diffusion de vidéos 4K. La fréquence de transmission sur un système DFA serait de 3 300 MHz.
- Un boîtier de modulation des signaux à débit élevé, comme 16 APSK et 32 APSK, a été ajouté afin de s'adapter à la transmission pour le service de diffusion de vidéos 4K.
