Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the size of an optical distributing box by using a branch coated optical fiber instead of a FO cord, and to prevent a direct incidence of intense light which causes problems on transmissions such as noise occurrence on an optically almost exposed single core line even when working by opening the door of the optical distributing box. SOLUTION: The branch coated optical fiber is arranged in a box body 6 having a door 3, and a light shielding plate 1 is arranged between the door and the branch coated optical fiber.
