Positioning jig of optical fiber loop device

The invention relates to the technical field of optical fiber loop device processing, in particular to a positioning jig of an optical fiber loop device. The positioning jig of the optical fiber loop device comprises a positioning assembly and a clamping assembly, a positioning groove is formed in the positioning assembly and comprises a bending groove, the bending groove is used for containing and positioning a loop bending part of an optical fiber loop part, and the clamping assembly is installed on the positioning assembly and can move relative to the positioning assembly. The clamping assembly is used for clamping and fixing the optical fiber connecting part, the positioning jig limits the bending radius of the optical fiber loop part through the bending groove in the positioning assembly, accurate control over the bending radius of the loop bending part is achieved, and the machining length of the optical fiber connecting part is adjusted through the clamping assembly. According to the positioning jig of
