AI Technical Summary

Technical Problem

Existing EML TO-CAN components suffer from low spectral performance and focal length testing efficiency, especially due to the bottleneck in testing efficiency caused by two fiber couplings.

Method used

The focal length and spectral measurements are combined into one, using multimode fiber for single coupling, and the test is performed by combining an altitude probe and a spectrometer to calculate the focal length and spectral data.

🎯Benefits of technology

This greatly improved testing efficiency, shortened testing time, increased production capacity, and achieved cost reduction and efficiency improvement.
