An ODF unit box disclosed by the utility model is characterized in that the ODF unit box comprises an ODF unit and a box body, wherein the ODF unit is used for protecting an optical fiber; and the box body is arranged at the periphery of the ODF unit and comprises a plurality of baffle plates, and at least one baffle plate is fixed to other baffle plates through magnetic powder. By adopting the magnetic powder, magnetic type structures of the baffle plates are realized, so that the baffle plates can be closed or opened easily; by adopting the magnetic type structures, the baffle plates can be opened or closed directly when communication lines in the ODF unit box are in fault detection or processing; absorption is easy, so that operation inconvenience in the maintenance process is avoided; in addition, detachment or damage of an occlusion port, caused by multiple times of opening and closing of the ODF unit box, is avoided.
