In-Building Optical systems for broadcast signal transmissions (TA 5)

This part of IEC 60728 is applicable to in-building optical transmission systems for broadcast signal transmission that consist of optical transmitter, optical amplifiers, splitters, V-ONUs, etc. These systems are primarily intended for television and sound signals using digital transmission technology. This document specifies the basic system parameters and methods of measurement for in-building optical distribution systems between building network interface (BNI) and home network interface (HNI) in order to assess the system performance and its performance limits.
This document is also applicable to broadcast signal transmission using a telecommunication network if it satisfies the requirements of optical section of this document. This document describes RF transmission for fully digitalized broadcast and narrowcast (limited area distribution of broadcast) signals over an FTTH network and introduces xPON system as a physical layer media. The detailed description of the physical layer is out of the scope of this document. The scope is limited to RF signal transmission over optical network, thus, it does not include IP transport technologies, such as IP Multicast and associate protocols.
This standard specifies the required system performance of all-optical building networks in order to connect with FTTH networks which are defined by IEC60728-113 and IEC60728-13-1. Use of In-building optical networks is very effective for saving cost (installation and maintenance) and enabling future network up-grades, especially in huge apartment buildings. In this document, the optical wavelengths and electrical frequency bands listed in Table 1 - and Table 2 - are considered to be used.

Kabelnetze für Fernsehsignale, Tonsignale und interaktive Dienste - Teil 115: Optische In-Haus-Anlagen zur Übertragung von Rundfunksignalen

Réseaux de distribution par câbles pour signaux de télévision, signaux de radiodiffusion sonore et services interactifs - Partie 115: Systèmes optiques internes aux immeubles pour la transmission de signaux de diffusion

L'IEC 60728-115:2022 s'applique aux systèmes de transmission optique internes aux immeubles pour la transmission de signaux de diffusion. Ces systèmes se composent d'émetteurs optiques, d'amplificateurs optiques, de répartiteurs, de V-ONU, etc. Ils sont principalement prévus pour la télévision et les signaux sonores qui utilisent une technologie de transmission numérique. Le présent document spécifie les paramètres de base du système et les méthodes de mesure des systèmes de distribution optique internes aux immeubles entre les interfaces de réseau de bâtiment (BNI, Building Network Interfaces) et les interfaces de réseau domestique (HNI, Home Network Interfaces), afin d'évaluer les performances du système et ses limites de performances. Le présent document s'applique également à la transmission des signaux de diffusion par un réseau de télécommunication, si celui-ci satisfait aux exigences de la partie du présent document consacrée à l'optique. Le présent document décrit la transmission de signaux radiofréquence en tant que signaux de diffusion générale et de diffusion ciblée (distribution de la diffusion dans une zone limitée) entièrement numérisés sur un réseau de desserte par fibre de l'abonné et introduit le système X-PON comme support de la couche physique. La description précise de la couche physique ne fait pas partie du domaine d'application du présent document. Etant donné que le domaine d'application se limite à la transmission des signaux RF sur les réseaux optiques, les technologies de transport par protocole Internet (IP), comme la multidiffusion IP et les protocoles associés, ne sont pas incluses. Le présent document spécifie les performances système exigées de réseaux entièrement optiques d'immeubles afin d'établir des connexions aux réseaux de desserte par fibre des abonnés, définis dans l'IEC 60728-113 et I'IEC 60728-13-1. L'utilisation de réseaux optiques internes aux immeubles est très efficace pour réduire les coûts (installation et maintenance) et permettre de futures améliorations, en particulier dans les grands immeubles résidentiels.
