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 optical line terminal (OLT) in order to output optical signals of the video-optical line terminal (V-OLT) and the optical line terminal (OLT) by multiplexing the optical signals. The VOLT receives cable TV, master antenna TV, and satellite broadcasting optical signals inputted from a broadcasting service network so as to output received signals as a first optical signal having a predetermined wavelength band. The OLT includes a first downstream data optical transmitter and a first upstream data optical receiver and outputs a data communication signal inputted from a data service network as a second optical signal having different wavelength from the video-optical line terminal. The ONT block includes a video-optical network terminal (V-ONT) and an optical network terminal (ONT) in order to split multiplexed data communication signals, and cable TV broadcasting, master antenna TV broadcasting, and satellite broadcasting optical signals. The V-ONT processes the split cable TV broadcasting, master antenna TV and satellite broadcasting optical signals so as to provide subscribers with the split cable TV broadcasting, master antenna TV and satellite broadcasting optical signals. The optical network terminal (ONT) has an upstream data optical transmitter and a downstream data optical receiver so as to process split data communication signals. The optical distribution network (ODN) connects the optical line terminal block to the optical network terminal as an optical transmission medium.
