摘要： An optical transmission device includes a first optical output unit including a chip and outputting an optical signal having a predetermined wavelength according to a temperature, a second optical output unit including a chip of which a temperature is controlled independently of the chip of the first optical output unit and outputting an optical signal having a predetermined wavelength according to a temperature, a failure detecting unit detecting a failure of the chip in operation of the first optical output unit, a switching unit switching its operation to the chip of the second optical output unit whose output optical signal has a same wavelength as that of the optical signal of the chip in operation of the first optical output unit when the failure detecting unit detects the failure, and a transmitting unit transmitting the optical signal output from the chip of the second optical output unit.
