Abstract
The utility model discloses a rack type optical branching device which comprises an upper part module and a lower part module. A box body and a bottom plate are combined to form a rack, and an optical branching device module is fixed on the bottom plate. An input adapter is connected with an inlet at the right side of the optical branching device module through optical fibers, an output adapter is connected with an outlet at the lower side of the optical branching device module through optical fibers, and each of the optical fibers connecting the input adapter and the optical branching device module and each of the optical fibers connecting the output adapter and the optical branching device module are fixed on the bottom plate through a wire clamping device. The lower part module and the upper part module are of a symmetrical structure, and the upper part module is buckled with the lower part module to form the optical branching device. The rack type optical branching device provided by the utility model is provided with the wire clamping device, thereby enabling the optical fibers to be fixed on the bottom plate, and enabling the optical fibers not to wind and the like. In addition, the optical fibers are externally sleeved by a hollow plastic sleeve, thereby further protecting the optical fibers, and effectively avoiding a circumstance that optical path signals are lost when the optical fibers are bent or even broken off.
