[0002] An optical cable junction box is a type of junction device that provides termination and patching for backbone optical cables and distribution optical cables. After the optical cable is introduced into the optical cable junction box, it is fixed, terminated, and distributed with fiber. Then, jumpers are used to connect the backbone optical cable and the distribution optical cable.
