PROBLEM TO BE SOLVED: To enable the efficient wiring work by externally installing both of an optical fiber network unit for transmitting a video signal and an optical fiber network unit for transmitting a data signal. SOLUTION: A body case 11 stores a circuit board for the optical fiber network for transmitting a video signal and a circuit board for the optical fiber network unit for transmitting a data signal. Supporting legs 12 fix the body case 11 on the external wall of a building. Cooling fins 13 and 14 are disposed on a surface of the body case 11 so as to face the external wall of the building. The supporting legs 12 form a space for storing the cooling fins 13 and 14 and an air flow path in the vertical direction between the body case 11 and the external wall of the building.
