Embodiments as shown in fig. 1 to 5, a wavelength division multiplexing cable box includes an upper cover 1 and a base 2, and the upper cover 1 and the base 2 are detachably connected. The wavelength division multiplexing optical fibers 6 are all arranged in the base 2; specifically, the wire arranging component 3 is mounted at the rear part of the base 2, the wire arranging component 3 comprises a bottom plate 31 and a pair of winding sleeves 32, and the winding sleeves 32 are respectively positioned at two ends of the bottom plate 31.

Meanwhile, a plurality of uniformly distributed supporting plates 331 are fixed to the side wall of the bottom plate 31, and the specific number of the supporting plates 331 can be adjusted according to actual needs, for example, as shown in fig. 2, the number of the supporting plates 331 is nine, and a limiting plate 332 extending inward is also vertically fixed to the end of each supporting plate 331. The winding sheath 32 and the stopper plate 332 of the support plate 331 are arranged to cross each other, the optical fiber 6 is wound in order with the sidewalls of the pair of winding sheaths 32 as supports, and the wound optical fiber 6 is stopped by the stopper plate 332, thereby preventing the optical fiber 6 from being randomly wound due to the movement of the cable box.

As shown in fig. 2, the components of the wavelength division multiplexing mainly include an adapter 4, a converter 5, and a splitter 7. The adapter 4 and the converter 5 are respectively arranged at two sides of the front end of the base, one end of the adapter 4 extends out of the base 2 through a plurality of connecting ports, and the other end is connected with a plurality of optical fibers 6; meanwhile, one end of the converter 5 extends out of the base 2 through a connector, and the other end of the converter is connected with a single optical fiber 6; the optical fibers 6 between the converter 5 and the adapter 4 are connected by a splitter 7.

Specifically, as shown in fig. 2, 4 and 5, a pair of mounting seats 22 are mounted on both sides of the front end of the base, the adapter 4 is fixedly mounted on one of the mounting seats 22, and the converter 5 is fixedly mounted on the other mounting seat 22.
