Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transmission rate of the optical module is continuously increased to meet demand, then the transmission capacity is improved, but the signal quality and reliability deteriorate over long distances
Solution Approach 1:
The optical module segments the transmission function into multiple components: light emitting chips for signal generation, optical multiplexer for wavelength division multiplexing, optical demultiplexer for signal separation, and light receiving chips for detection. This segmentation allows each component to be optimized for high-speed operation while maintaining overall signal quality through coordinated operation of the segmented system.
2Measurement precision
If optical components are precisely aligned to improve signal conversion accuracy, then the conversion precision is improved, but the device complexity and alignment difficulty increase
Solution Approach 1:
The patent merges multiple optical components (light emitting chips, optical multiplexer, optical demultiplexer, light receiving chips) into an integrated optical module structure. This merging reduces the number of separate alignment operations needed compared to using discrete components, while maintaining high conversion accuracy through the integrated design that pre-establishes optical paths between components.
Solution Approach 2:
The optical multiplexer and optical demultiplexer serve as intermediary components that facilitate precise signal conversion. The optical multiplexer combines multiple wavelengths with precise spectral control, and the optical demultiplexer separates them with corresponding precision, acting as mediators that maintain signal accuracy while managing the complexity of multi-wavelength transmission.
