OPTICAL TRANSMITTING SYSTEM, OPTICAL TRANSMITTER INCLUDED IN THE SAME AND OPTIC TRANSMITTING METHOD

摘要

PURPOSE: An optical transmitter system transmitting a broadcast signal and a digital signal, an optical transmitter and an optical transmission method are provided to control the generation of mode partition noise and maintain the size of the broadcasting optical signal having a single wavelength. CONSTITUTION: An optical source unit(300) modulates a broadcast signal and outputs a first broadcasting optical signal. A demultiplexer(302) outputs a second broadcast optical signal by partitioning the outputted first broadcasting optical signal and the second broadcast optical signal. A noise controller outputs the second broadcasting optical signal at a specific level.
