[0001] The utility model relates to the technical field of communications, in particular to an optical fiber splitter box. Background Art

[0002] Fiber optic splitter boxes connect main optical cables with distribution cables and are essential for achieving fiber-to-the-home (FTTH). Existing fiber optic splitter boxes, such as those disclosed in Chinese utility model patent No. 201822014090.6 (application publication No. CN 209387928 U), "An Fiber Optic Splitter Box," include a fiber fusion splicing module, multiple fiber storage trays, and an adapter holder. These components are typically laid flat on the bottom wall of the splitter box, occupying a significant amount of space.

[0003] To better meet user needs, fiber optic splitter boxes are becoming increasingly integrated and miniaturized. These boxes often combine hot-melt splicing with optical splitting and branching functions while maintaining a minimal footprint. However, even with optimized structural layouts, these splitter boxes, as long as they remain flat, can only maintain a relatively large volume. Therefore, further improvements are needed to the existing structure of fiber optic splitter boxes.
