Cable tapping protection box for optical communication

The invention discloses a cable tapping protection box for optical communication. The cable tapping protection box comprises a box body and an upper cover which are rotatingly connected. One side of the upper cover is rotatingly connected to an upper end of the box body by an articulated manner, and a sealing ring is embedded in an upper end edge of the box body. A movable clamping structure is further cooperatively disposed on a side of a position where box body and the upper cover are rotatingly connected, a wire inlet pipe passes through one end of a side wall of the box body, and branch wire holes pass through another end. Two ends of the wire inlet pipe are movably connected to a fixing sleeve for locking a cable and a waterproof sleeve for sealing and waterproofness, and a wire separating disk with limited rotation is rotatingly connected between the wire inlet hole and the branch wire holes. Cables are fixed and water seepage is avoided by the design of the fixing sleeve and thewaterproof sleeve, the d
