Technical Field
[0001] This application relates to the field of optical fiber communication technology, and in particular to a splitter fusion splicing box. Background Technology
[0002] With the large-scale construction of fiber-to-the-home, the network is profoundly impacting our lives. The deployment of fiber optic networks and the laying of optical cables are extremely important aspects. Network cabling and optical splitting products have become an indispensable product for broadband access construction.
[0003] Currently, common fiber optic splicing boxes mainly include fixed splicing boxes and drawer-type splicing boxes. Fixed splicing boxes have immovable splicing trays, narrow operating space, and the cables are prone to cross-tangling. Drawer-type splicing boxes have splicing trays that can be pulled out via slide rails, which is convenient to operate. However, the cable inlet holes of existing drawer-type structures are mostly located on the back, which can easily squeeze the cables when pulling them out. In addition, when laying high-density cables, the wiring becomes messy, which is not convenient for cable management and maintenance.
[0004] Therefore, this application provides a splitter fiber splicing box. Utility Model Content
