Optical fiber connector and optical splitter

An optical splitter, comprising an optical fiber connector and an optical waveguide device, wherein the optical fiber connector comprises a housing and a plurality of optical fibers arranged in parallel;

• the housing encloses the plurality of optical fibers, and end faces at both ends of the optical fibers are exposed outside the housing;
• and a part that is of at least two of the plurality of optical fibers and that is enclosed by the housing is provided with a grating, and gratings on the at least two optical fibers are different from each other;
• and
• the optical waveguide device comprises a splitter substrate and an optical waveguide located on the splitter substrate, wherein the optical waveguide has a first port and a plurality of second ports, the first port is connected to all of the plurality of second ports, and the plurality of second ports are coupled to a plurality of optical fibers in the optical fiber connector in one-to-one correspondence.
