Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wavelength spacing is reduced to increase bandwidth capacity, then more wavelengths can be transmitted, but cross-talk increases and requires precise control leading to higher power consumption
Solution Approach 1:
The patent divides the multi-wavelength optical signal into multiple groups using wavelength splitters. Each wavelength group is then independently modulated by separate modulators. This segmentation allows the system to process and transmit different wavelength groups independently, reducing the power consumption associated with controlling all wavelengths simultaneously while maintaining high bandwidth capacity through the multiplexed wavelengths.
2Reliability
If precise control is implemented to prevent cross-talk between wavelengths, then signal quality improves, but device complexity and power consumption increase
Solution Approach 1:
The patent uses wavelength splitters to segment the multi-wavelength signal into distinct wavelength groups that are directed to different modulators. This physical segmentation in the optical domain eliminates the need for complex electronic control mechanisms to prevent cross-talk, as each wavelength group is independently processed. The segmentation approach maintains signal quality while reducing control complexity.
Solution Approach 2:
The wavelength splitters act as intermediary devices that physically separate different wavelength components before modulation. This intermediary structure prevents cross-talk by ensuring that wavelengths are routed to appropriate modulators through optical filtering and spatial separation, rather than relying on complex control algorithms to manage interference between channels.
3Quantity of substance
If all wavelengths are allocated to each node, then resource availability is maximized, but resource utilization efficiency decreases due to wasted unused wavelengths and power
Solution Approach 1:
The patent segments the multi-wavelength optical signal into multiple wavelength groups using wavelength splitters, and each group is independently modulated and transmitted. This allows network nodes to receive only the specific wavelength groups they need, rather than all wavelengths. Consequently, resource availability is maintained through the full multi-wavelength signal, while resource utilization efficiency improves because nodes process only their required wavelengths, eliminating waste of unused wavelengths and associated power consumption.
