Abstract
A first optical transmission device 1 is connected to a second optical transmission device 2, and the second optical transmission device 2 is connected to a third optical transmission device 3, via a plurality of optical transmission lines. Transfer data and a clock signal synchronous with the transfer data are transferred in parallel from the first optical transmission device 1 to the second optical transmission device 2 through the plurality of optical transmission lines. Transfer data and a clock signal synchronous with the transfer data are transferred in parallel from the second optical transmission device 2 to the third optical transmission device 3 through the plurality of optical transmission lines. The second optical transmission device 2 stops outputting data to the third optical transmission device 3 when the clock signal transferred from the first optical transmission device 1 cannot be detected.
