Abstract

The invention discloses a multiplexing device and method for testing light sources. The device includes a wide-spectrum light source, a diffraction grating and a light source multiplexer; the wide-spectrum light source emits broad-spectrum illumination light, which passes through the diffraction grating to form monochromatic illumination light; the light source multiplexer has a plurality of light output ports, Each optical output port corresponds to a signal receiver, and the multiple signal receivers are connected to the input end of the logic circuit, and the output end of the logic circuit is connected to the optical path controller and the rotating motor driving circuit of the diffraction grating. The method uses the test light source multiplexing device. The invention reduces the cost of the whole set of equipment by multiplexing the monochromatic light source, and reduces the difficulty of debugging the light source when the test equipment is assembled. With the signal synchronization device, the test process of multiple test equipment is uniformly scheduled, and the impact of light source multiplexing on the overall test efficiency is within an acceptable range.

Description

technical field [0001] The invention belongs to the field of optical fiber testing, and more specifically relates to a method for multiplexing a testing light source. Background technique [0002] Optical fiber is a widely used information carrier in the field of modern communication, in which signals are transmitted in the form of light energy. The transmission performance of optical fiber is an important index to measure the quality of optical fiber transmission performance, and it is an indispensable link to test the transmission performance of optical fiber in the manufacturing process. [0003] The transmission performance test of optical fiber mostly adopts the power method, that is, monochromatic light is injected into the optical fiber, and the change of the optical power of the monochromatic light after transmission into the optical fiber is detected. The performance of monochromatic light here: parameters such as stability, spectral width, and power have a signifi...
