Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wavelength separating means with fixed transmission wavelength is used, then the system structure is simple, but the reception wavelength cannot be flexibly changed
Solution Approach 1:
The patent applies the dynamics principle by making the wavelength filter tunable rather than fixed. The wavelength filter can dynamically adjust its transmission wavelength based on received wavelength information, allowing the reception wavelength to be flexibly changed while maintaining system adaptability without requiring complex reconfiguration of the entire wavelength separating means.
2Use of energy by moving object
If wavelength separating means with fixed transmission wavelength is used, then the device complexity is low, but power consumption cannot be reduced
Solution Approach 1:
The patent applies the self-service principle by enabling the optical transceiver to autonomously adjust its reception wavelength based on wavelength information received from other transceivers. The determination unit automatically determines whether to adjust the wavelength filter without requiring external control, allowing power consumption reduction through selective wavelength tuning while maintaining simple device architecture.
3Adaptability or versatility
If wavelength separating means is used, then optical signal reception is enabled, but the reception wavelength is determined by transmission wavelength setting
Solution Approach 1:
The patent applies the feedback principle by using received wavelength information from other optical transceivers to automatically adjust the local wavelength filter settings. The optical transceiver receives wavelength information, determines the appropriate reception wavelength, and configures the wavelength filter accordingly, enabling independent wavelength selection without manual configuration while simplifying operation.

AI summary
An objective is to easily set a wavelength of an optical signal received by an optical transceiver. A first reception unit receives a first optical signal including identification information and reception wavelength information. A determination unit determines whether the identification information satisfies a predetermined condition. A wavelength filter has a tunable wavelength and transmits a second optical signal of the transmission wavelength included in an input optical signal. When the judgment unit judges that the identification information satisfies the predetermined condition, a wavelength instruction unit instructs the wavelength filter to use a transmission wavelength based on the reception wavelength information. A second reception unit receives a second optical signal.
