DIN EN 60728-13-1:2013-04

Standards of the DIN EN 60728 (VDE 085) series deal with cable networks including equipment and associated methods of measurement for headend reception, processing and distribution of television signals, sound signals and their associated data signals and for processing, interfacing and transmitting all kinds of signals for interactive services using all applicable transmission media. This standard applies to the FTTH system of broadband broadcast signal transmission which conveys satellite broadcast signals using one or multiple optical wavelengths. It is provided for cable/satellite operators to extend their broadband services in order to avoid interference between optical wavelengths based on the technologies described in DIN EN 60728-13 (VDE 0855-13). The purpose of this standard is the precise description of the FTTH system for expanding broadband broadcast signal transmission. It applies for various service signals (for example, internet television, mobile telephone) and digital and broadcast satellite and communication satellite signals. The scope is limited to the RF signal transmission with FTTH systems and does not include IP transport technologies. The annexes provide the user of the standard with important means. Annex A describes the system composition and model system based on this standard, and Annex B describes basic concepts for optical wavelength division multiplexing and adds notes for system configuration. Annex C gives the minimum wavelength separation, and Annex D explains the relationship between C/N degradation and rain attenuation. The responsible committee is K 735 "Kabelnetze und Antennen für Fernsehsignale, Tonsignale und interaktive Dienste" ("Cable networks for television signals, sound signals and interactive services") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
