The purpose of this part of IEC 60728 is the precise description of the 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. The scope is limited to the RF signal transmission over the FTTH system, thus this part of IEC 60728 does not include IP transport technologies. Informative 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 S/N degradation and rain attenuation. This standard describes the pass-through method of satellite broadcast signals over the FTTH system which uses AM-FDM (SCM) transmission. For an FTTH system below 1 GHz refer to IEC 60728-113. This standard contains descriptions of the measurement methods and specifications for optical wavelength division multiplex and for xPSK(QPSK,8PSK,TC8PSK) and 16APSK modulation systems. It specifies the downstream video signal transmission and thus the two-way optical transmission system is out of the scope of this standard. 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 fo3.1r cable/satellite operators to extend their broadband services in order to avoid interference between optical wavelengths based on the technologies described in IEC 60728-113. This standard also includes technical descriptions for new transmission signals, such as 4K video contents, which requires more bandwidth expansion than the system described in IEC 60728-13-1 Ed. 2.0. In this standard, it is assumed that the 4K original video contents and other new services expected in the future (such as 8K, 3D-Hologram, and/or video on demand (VOD) etc.) will be transmitted on cable platforms via satellite link
