1Use of energy by moving object
If the transmitter arbitrarily changes wavelength settings, then power consumption is reduced, but the receiver's ability to restore the original wavelength deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the transmitter notifies the receiver of wavelength settings through control signals, and the receiver uses this information to correctly restore and process the optical signals. This feedback loop ensures that even when wavelengths are dynamically changed, the receiver maintains accurate wavelength-to-data mapping, resolving the contradiction between flexible wavelength switching and reliable signal restoration.

If optical wavelength-multiplexing communication is used for high-speed data transmission, then data capacity increases, but power consumption and device complexity increase
Solution Approach 1:
The patent employs dynamic wavelength assignment where the transmitter can arbitrarily change wavelength settings based on communication conditions. This dynamic approach allows the system to optimize power consumption by selecting appropriate wavelength combinations while maintaining high data transmission capacity through wavelength division multiplexing, thus resolving the contradiction between productivity and energy consumption.
