ABSTRACT:
A fiber to the home (FTTH) system based on a passive optical network (PON) includes an optical line terminal (OLT) block, an optical network terminal (ONT) block, and an optical distribution network (ODN). The ONT block includes a video-optical line terminal (V-OLT) and an OLT to output optical signals of the V-OLT and the OLT by multiplexing the optical signals. The V-OLT receives cable TV (CATV), master antenna (MATV), and satellite broadcasting (SB) optical signals inputted from a broadcasting service network to output received signals as a first optical signal having a predetermined wavelength band. The ONT block includes a video-optical network terminal (V-ONT) and an (ONT) to split multiplexed data communications signals, and CATV broadcasting, MATV broadcasting, and (SB) optical signals. The V-ONT processes the split CATV broadcasting, MATV, and (SB) optical signals to provide subscribers with the split cable CATV, MATV and SB optical signals.
