Patent ID: 8331402

Claim:
An optical transmission device that transmits data to a plurality of destination addresses, comprising: a first attaching device that attaches a header of a first bit rate to data of the first bit rate, the header of the first bit rate including identification data for identifying a destination address of the data of the first bit rate; a second attaching device that attaches the header of the first bit rate to data of a second bit rate greater than the first bit rate, the header of the first bit rate including identification data for identifying a destination address of the data of the second bit rate; a first scrambler that performs a scrambling process, by using a clock corresponding to the first bit rate, on signals that are obtained by the first attaching device and the second attaching device; a second scrambler that performs a scrambling process, by using a clock corresponding to the second bit rate, on the data of the second bit rate in the second attaching device; and a transmitter that transmits the signals obtained due to the scrambling process by the first scrambler or the second scrambler.
