The invention discloses an optical cable
fiber distribution box. A detachable inner plate is fastened to the bottom face in the box body, stackable and turnable
fusion welding disks are arranged on a
fiber storage plate, a turnable upper layer plate is arranged on the top of the
fusion welding plates, an
optical fiber berthing space plate used for berthing optical fibers which do not enter homes yet is arranged on the top face of the upper layer plate, a mounting support used for an
optical fiber adapter to be inserted in is arranged on one side of the
optical fiber berthing space plate, and a filer inlet hole and a
fiber outlet hole are formed in the portions, on the front and the back of the mounting support of the adapter, of the upper layer plate. The detachable inner plate can be placed outside the box body for mounting the optical fibers, the optical fibers can be welded conveniently in a fusion mode and the number of cores of the connected-in optical fibers can be expanded conveniently because the stackable and turnable
fusion welding disks are arranged on the fiber storage plate, wire
jumping and fusion
welding can be carried out in a layered mode because the upper layer plate, the optical fiber berthing space plate and the mounting support of the adapter are arranged, and meanwhile the wire
jumping can be more convenient and flexible to carry out. The optical cable fiber distribution box is compact in structure and convenient to install, and the optical fibers are high in connecting-in quality and flexible to connect in.
