Abstract: Optical transmission device includes: a reception unit, a detector, a mapping unit and a transmission unit. The reception unit receives a first signal transmitted based on a first clock. The detector detects rate information for storing client data in the first signal in a transmission frame based on the first signal. The mapping unit generates the transmission frame by mapping the client data to a payload area of the transmission frame based on the rate information. The transmission unit outputs the transmission frame or a second transmission frame including the transmission frame to a network. The reception unit, the detector, and the transmission unit are implemented by a hardware circuit, and the mapping unit is implemented by software processing using a processor.
