Engineering Contradiction Analysis
1Extent of automation
If manual tuning and connection methods are used for optical transceivers, then installation and troubleshooting can be performed with existing equipment, but installation costs increase and troubleshooting time is extended
Solution Approach 1:
The optical transceiver automatically tunes itself by generating and analyzing tuning messages without external intervention. The device performs self-diagnosis and self-configuration by comparing received tuning messages against stored signal patterns, eliminating the need for manual tuning operations and reducing installation costs.
Solution Approach 2:
The system changes the wavelength parameter of the optical transceiver automatically by identifying the correct tuning message pattern. The transceiver adjusts its operational wavelength based on the matched signal pattern, enabling automatic adaptation to the correct communication channel without manual parameter setting.
2Productivity
If manual tuning procedures are implemented, then existing optical network infrastructure can be used, but installation costs and troubleshooting time increase significantly
Solution Approach 1:
The system pre-stores multiple signal patterns corresponding to different tuning messages in the optical transceiver. During installation, the device quickly compares the received tuning message against these pre-stored patterns to identify the correct wavelength configuration, eliminating the need for time-consuming manual troubleshooting and acceleration the installation process.
3Ease of operation
If automatic tuning methods are implemented, then installation costs and troubleshooting time are reduced, but the system requires complex signal processing operations
Solution Approach 1:
The system replaces manual mechanical tuning operations with optical signal processing. The transceiver uses optical dot product operations to compare received tuning messages with stored signal patterns, substituting physical manual adjustment with automated optical field computations that simplify the user operation while managing complexity through mathematical operations.
