Optical splitter, signal transmission method and passive optical network

The invention discloses an optical splitter, including optical splitter, a reflector and a photoelectric detector, the detector is connected with the optical splitter, the other end is connected with the reflector, the splitter is first output terminal coupled to the second output end of the main optical fiber, the coupling of the splitter is to the photoelectric detector; wherein the first light signal receiving and transmitting the optical network unit of the splitter; the first light signal by a certain percentage of the transmission of the second output end to the photoelectric detector; photoelectric detector receives a certain percentage of the first optical signal; the first proportion of the first optical signal conversion for signals; the second optical signal of the reflector receiving and transmitting optical line terminal; through the electrical signal detector of the conversion will be reflected back into the second optical signal line terminal. The embodiment of the invention overcomes the problems that the optical signal loss of the existing optical splitter is too large, the distance of the uplink transmission and the branching ratio are limited.
