Engineering Contradiction Analysis
1Manufacturing precision
If manual parameter sweeping is used to tune optical transceivers, then the transceiver can be tuned to desired performance, but the tuning process takes up to two hours and requires numerous iterations
Solution Approach 1:
The patent replaces manual parameter sweeping (mechanical/systematic trial-and-error approach) with a machine learning-based tuning system. The ML model predicts optimal tuning parameters directly, eliminating the need for iterative parameter sweeping and reducing tuning time from hours to minutes while maintaining accuracy.
Solution Approach 2:
The system performs preliminary training by collecting training data from initial parameter sweeps and waveforms, then uses this pre-trained model to predict optimal parameters for new transceivers. This preliminary action creates a knowledge base that accelerates subsequent tuning operations without requiring full parameter sweeps.
2Reliability
If traditional parameter sweeping methods are used, then tuning can be accomplished, but the manufacturing expense increases due to time consumption
Solution Approach 1:
The patent replaces expensive iterative parameter sweeping with a machine learning model that predicts optimal parameters. The ML system maintains tuning reliability by learning from training data while dramatically reducing the time and associated manufacturing costs of the tuning process.
3Productivity
If machine learning is implemented to reduce tuning iterations, then tuning speed increases, but system complexity increases
Solution Approach 1:
The patent introduces a machine learning model as an intermediary between the transceiver and the tuning process. The ML model acts as a mediator that predicts optimal parameters based on training data, simplifying the overall system by replacing complex iterative tuning algorithms with a trained prediction model.
4Loss of time
If fewer tuning iterations are performed, then manufacturing time decreases, but measurement precision requirements increase
Solution Approach 1:
The system performs preliminary training by collecting comprehensive waveform data and parameter information during the training phase. This preliminary action builds a robust model that can make accurate predictions with fewer iterations, effectively shifting the measurement precision requirements to the training phase rather than the production tuning phase.

AI summary
A test and measurement device has a connection to allow the test and measurement device to connect to an optical transceiver, one or more processors, configured to execute code that causes the one or more processors to: initially set operating parameters for the optical transceiver to average parameters, acquire a waveform from the optical transceiver, measure the acquired waveform and determine if operation of the transceiver passes or fails, send the waveform and the operating parameters to a machine learning system to obtain estimated parameters if the transceiver fails, adjust the operating parameters based upon the estimated parameters, and repeat the acquiring, measuring, sending, and adjusting as needed until the transceiver passes. A method to tune optical transceivers includes connecting a transceiver to a test and measurement device, setting operating parameters for the transceiver to an average set of parameters, acquiring a waveform from the transceiver, measuring the waveform to determine if the transceiver passes or fails, sending the waveform and operating parameters to a machine learning system when the transceiver fails, using the machine learning system to provide adjusted operating parameters, setting the operating parameters to the adjusted parameters, and repeating the acquiring, measuring, sending, using, and setting until the transceiver passes.
