    • The invention relates to a package starting control device determining a moment and a sequence of starting a package corresponding to an individual wavelength to be wavelength-division-multiplexed in a wavelength division multiplex transmission device. An object of the invention is to provide a package starting control device capable of effectively increasing or decreasing the number of wavelengths at low cost without changing a basic structure drastically. The package starting control device is constructed such that operational states of optical modules that generate optical signals wavelength-division-multiplexed into wavelength division multiplexed optical signals are monitored, the optical signal output by packages that generate the optical signals wavelength-division-multiplexed into the wavelength division multiplexed optical signals during a period when any of the operational states is not in a steady state is restricted and the restriction of the optical signal output by one package of the packages each time the period elapses is released.
