Distributed CATV Inputs in FTTH-PON System

This is about CATV system on FTTH-PON network with a new idea dealing with multiple input points of the video broadcasting station by using the same wavelength of 1550 nm. The externally modulated intensity of different sources does not produce any interference that became an advantage of this system. The main purpose of this study is to determine the possibility of broadcasting of multiple inputs CATV with the lengths of 20 km despite the only video input.
