Cable networks for television signals, sound signals and interactive services - Part 6: Optical equipment

IEC 60728-6:2011(E) lays down the measuring methods, performance requirements and data publication requirements of optical equipment of cable networks for television signals, sound signals and interactive services. This third edition cancels and replaces the second edition published in 2003 of which it constitutes a technical revision. It includes the following significant technical changes with respect to the previous edition: - The normative references were updated. - The methods of measurement for optical power and return loss were substituted by references to other standards. - The method of measurement for polarization dependent loss was deleted. - A method of measurement for carrier-to-crosstalk ratio (CCR) was added. - The methods of measurement for CSO and CTB of optical amplifiers were substituted by a method of measurement for microscopic gain tilt of optical amplifiers. This parameter can be used for calculating the second order distortion of optical amplifiers according to the method described in the new Annex B. New classes for optical transmitters and receivers have been defined.

Kabelnetze für Fernsehsignale, Tonsignale und interaktive Dienste - Teil 6: Optische Geräte

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 6: Matériels optiques

L'IEC 60728-6:2011 présente les méthodes de mesure, les exigences de performance et les exigences de publication de données des matériels optiques des réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs. La présente norme • s'applique à tous les émetteurs, récepteurs, amplificateurs, coupleurs directifs, isolateurs, dispositifs de multiplexage, connecteurs et épissures, optiques, utilisés dans les réseaux de distribution par câbles; • couvre la gamme de fréquences de 5 MHz à 3 000 MHz; • identifie les exigences de performance garanties pour certains paramètres; • présente les exigences de publication des données avec une performance garantie; • décrit les méthodes de mesure pour l'essai de conformité. Toutes les exigences et les données publiées concernent les niveaux de performance minimums dans la gamme de fréquence spécifiée et dans des conditions d'adaptation correcte, tels que pouvant s'appliquer aux réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs. L'IEC 60728-6:2011 annule et remplace la deuxième édition parue en 2003, dont elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente. • Les références normatives ont été mises à jour. • Les méthodes de mesure de la puissance optique et de l’affaiblissement de réflexion ont été remplacées par des références à d’autres normes. • La méthode de mesure de l’affaiblissement dépendant de la polarisation a été supprimée. • Une méthode de mesure du rapport porteuse sur diaphonie (CCR) a été ajoutée. • Les méthodes de mesure de CSO (Distorsion composite d’ordre deux) et de CTB (Battement triple composite) des amplificateurs optiques ont été remplacées par une méthode de mesure de la variation de gain microscopique des amplificateurs optiques. Ce paramètre peut être utilisé pour calculer la distorsion d’ordre deux des amplificateurs optiques selon la méthode décrite à la nouvelle Annexe B. • De nouvelles classes d’émetteurs et récepteurs optiques ont été définies.

Kabelska omrežja za televizijske signale, zvokovne signale in interaktivne storitve - 6. del: Optična oprema (IEC 60728-6:2011)

Ta del IEC 60728 predpisuje merilne metode, zahteve za zmogljivost in zahteve za objavo podatkov za optično opremo kabelskih omrežij za televizijske signale, zvočne signale in interaktivne storitve. Ta standard - velja za vse optične oddajnike, sprejemnike, ojačevalnike, smerne spojnike, izolatorje, multipleksne naprave, konektorje in spoje, ki se uporabljajo v kabelskih obrežjih; - zajema frekvenčni razpon od 5 do 3000 MHz; OPOMBA: Zgornja meja 3000 MHz je podana kot primer in ne stroga vrednost. - opredeljuje zagotovljene zahteve za zmogljivost za določene parametre; - določa zahteve za objavo podatkov z zagotovljeno zmogljivostjo; - opisuje merilne metode za preskušanje skladnosti. Vse zahteve in objavljeni podatki se nanašajo na minimalne ravni zmogljivosti v določenem frekvenčnem razponu in v enakih okoliščinah, kot lahko veljajo za kabelska omrežja za televizijske signale, zvočne signale in interaktivne storitve.
