EN 60728-10:2014

Cable networks for television signals, sound signals and interactive services - Part 10: System performance for return paths

IEC 60728-10:2014 specifies the transparent return path of cable networks operated in the frequency range between 5 MHz and 85 MHz or parts thereof. The upper frequency limit of the return path is reduced to 65 MHz where FM radio signals are transmitted in a cable network. Higher frequencies may be used in fibre based networks. This third edition cancels and replaces the second edition published in 2005 and constitutes a technical revision. It includes the following changes: - update on the state-of-the-art of return path transmission in cable networks; - provisions for DOCSIS 3.0 and EuroDOCSIS 3.0 transmission standards; - revision of subclause 4.3 on measurement of channel level; - new subclause 4.12 for method of measurement of noise power ratio (NPR) on return paths; - new subclause 4.13 for 10-tone measurements; - new subclause 4.14 for method of measurement of modulation error ratio (MER); - revision of subclause 5.2 on analogue parameters influencing system performance.

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 10: Performances des systèmes de voie de retour

L'IEC 60728-10:2014 spécifie la voie de retour transparente des réseaux de distribution par câbles fonctionnant dans la totalité ou des parties de la bande de fréquences située entre 5 MHz et 85 MHz. La limite supérieure de fréquence de la voie de retour, pour laquelle les signaux radio FM sont transmis dans un réseau de distribution par câbles, est réduite à 65 MHz. Des fréquences plus élevées peuvent être utilisées dans des réseaux à fibres optiques. Cette troisième édition annule et remplace la deuxième édition publiée en 2005 dont elle constitue une révision technique. Elle inclut les modifications suivantes: - mise à jour de l'état de la technique de la transmission de voie de retour dans les réseaux de distribution par câbles; - dispositions pour les normes DOCSIS 3.0 et EuroDOCSIS 3.0 relatives à la transmission; - révision du paragraphe 4.3 sur la mesure des niveaux de canaux; - nouveau paragraphe 4.12 relatif à la méthode de mesure du rapport de puissance de bruit sur voie de retour; - nouveau paragraphe 4.13 relatif aux mesures à 10 porteuses; - nouveau paragraphe 4.14 relatif à la méthode de mesure du rapport d'erreur de modulation (MER); - révision du paragraphe 5.2, par rapport aux paramètres analogiques qui influencent les performances du système.

Kabelska omrežja za televizijske in zvokovne signale ter interaktivne storitve - 10. del: Lastnosti sistema za povratne poti (IEC 60728-10:2014)

Standard EN IEC 60728-10 določa pregledno povratno pot kabelskih omrežij, ki delujejo v frekvenčnem območju med 5 in 85 MHz. Kadar se radijski signali prenašajo prek kabelskega omrežja, se zgornja frekvenčna meja povratne poti zniža na 65 MHz. V optičnih omrežjih se lahko uporabijo višje frekvence. Ta standard ne obsega specifikacij prenosnih sistemov (npr. DOCSIS).
