Filed: 1983-09-30
Abstract: PURPOSE:To attain 2-way communication with low loss by allowing an optical fiber to input a signal in a single mode or a lower order mode and allowing a photodetector arranged near the other end of the fiber to receive the input in a higher order mode. CONSTITUTION:An optical signal outputted from one laser diode 3 is inputted to a single mode optical fiber 2, transmitted for a long range by using a multi- mode optical fiber 1 and then inputted again in a single mode optical fiber 2'.
