Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all raw data collected by digital coherent receivers is transmitted to a central analyzing device, then complete network analysis including nonlinear characteristics is achieved, but communication capacity is exceeded and real-time transmission becomes difficult
Solution Approach 1:
The patent extracts only the essential characteristics and abnormality indicators from the raw optical signal data using signal processing techniques. Instead of transmitting all raw data, the system extracts key parameters such as power levels, modulation characteristics, and anomaly markers, significantly reducing the data volume while preserving the information needed for network analysis.
Solution Approach 2:
The patent segments the data transmission process by dividing it into critical information that must be transmitted and redundant information that can be processed locally. The system segments raw signals into meaningful data packets containing only the essential network state information, enabling efficient transmission within communication capacity constraints.
2Quantity of substance
If data reduction is applied to reduce transmission volume, then communication capacity burden is reduced, but risk of losing main information such as nonlinear characteristics increases
Solution Approach 1:
The patent applies preliminary actions by pre-processing the optical signals at the receiving end before transmission. The system performs initial signal conditioning, filtering, and characteristic extraction in advance, ensuring that only processed and validated data is transmitted. This preliminary processing prevents information loss by establishing data quality standards before reduction.
Solution Approach 2:
The patent implements feedback mechanisms where the central analyzing device monitors the quality and completeness of reduced data. When critical information such as nonlinear characteristics is detected or suspected to be lost during reduction, the system requests re-transmission or adjusts reduction parameters to preserve essential information.
3Quantity of substance
If only reception power data is transmitted, then communication load is reduced, but detailed network analysis including physical characteristics becomes insufficient
Solution Approach 1:
The patent applies dynamic data transmission by adjusting the type and amount of data sent based on network conditions and analysis requirements. The system dynamically selects which parameters to transmit (power levels, modulation characteristics, error rates, nonlinear indicators) depending on the current network state and analysis needs, optimizing both communication efficiency and analysis precision.
