Abstract
For practical application in a telecommunications system, optical switch modules using MEMS mirror devices should be mechanical-vibration-proof, which is a fundamental environmental reliability criterion. To satisfy this requirement, we propose a design technique for vibration-proof mechanisms. This technique utilizes the dynamic characteristics of each mechanical component and an actual measurement of optical characteristics when mechanical vibration is applied. We evaluated the fundamental environmental characteristics of prototype optical switch modules, such as a wavelength-selectable switch module and a 3-D MEMS optical switch module. The results confirmed that the switching module satisfies the Telcordia GR-63 office vibration test with the application of vibration-proof mechanism, indicating that the MEMS optical switch module is suitable for practical use.
