送ネットワーク。In a train that performs data transmission by arranging a transmission station and a transmission line in the train, the transmission station includes an input photoelectric conversion section and an output electro-optic conversion section, the transmission line in the train is an optical fiber, and the transmission line in the train is an optical fiber. The transmission line between the optical fibers is characterized by comprising a spatial optical transmitter that converts the optical signal of the optical fiber into a spatial optical signal, and a spatial optical receiver that converts the spatial optical signal into the optical signal of the optical fiber.
