Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different wavelength settings are used for monitoring optical signals in trunk and branch segments, then monitoring capability is maintained, but device cost increases
Solution Approach 1:
The patent applies universality by enabling the same monitoring optical signal wavelength to be used across both trunk and branch segments. The wavelength selection reflector is configured to reflect monitoring optical signals of a specific wavelength back to the sending end, allowing a single wavelength setting to serve multiple functions in different network segments, thereby reducing device cost while maintaining monitoring capability.
2Reliability
If monitoring optical signals are sent through multiple transmission paths, then comprehensive monitoring is achieved, but simultaneous monitoring becomes challenging
Solution Approach 1:
The patent applies preliminary action by pre-configuring the wavelength selection reflector to reflect monitoring optical signals of a specific wavelength back to the sending end before the signals are transmitted through multiple paths. This pre-configuration ensures that monitoring signals from different segments can be simultaneously transmitted and monitored without timing coordination issues, as each segment's monitoring signal is automatically routed back to its respective sending end through the wavelength selection reflector.
3Reliability
If wavelength selection reflectors are used for monitoring, then optical path monitoring is enabled, but part commonality across trunk and branch is reduced
Solution Approach 1:
The patent applies universality by configuring the wavelength selection reflector to handle monitoring optical signals of a specific wavelength across both trunk and branch segments. This allows the same type of component (wavelength selection reflector) to be used uniformly throughout the network with a standardized wavelength setting, thereby maintaining part commonality while enabling comprehensive optical path monitoring.
