The invention relates to the technical field of optical fibers, and discloses an optical fiber cable cutting device based on a light perception control principle. The optical fiber cable cutting device based on the light perception control principle comprises a workbench. A support is fixedly connected with the exterior of the workbench, a cutting assembly is movably connected with the exterior ofthe support, and supporting rods are fixedly connected with the exterior of the support. Limiting blocks are fixedly connected with the exteriors of the supporting rods, and limiting plates are fixedly connected with the interiors of the limiting blocks. Moving frames are movably connected with the exteriors of the limiting plates, teeth are arranged inside the moving frames, and connecting rodsare fixedly connected with the exteriors of the moving frames. By means of the interaction of the limiting blocks, the limiting plates, the moving frames, the teeth, first gears, second gears, gear rings, rotating shafts, rotary rods, the connecting rods and press plates, an optical fiber cable can be tightly pressed and fixed when the optical fiber cable is cut, the situation that the optical fiber cable slips and deviates in the cutting process is avoided, and therefore the optical fiber cable can be fully cut, and the cut surface is relatively flat.
