Abstract
The goal of this study is to perform a complement of the existing Telcordia standard in order to assess the reliability of commercial optical microswitches in a space environment. A standard qualification (Telcordia / Bellcore) already exists for ground applications, but some topics (in particular radiation and in vacuo operation), which are a specificity of the space environment, are not covered. To this purpose, a specific test battery (γ-ray, neutrons, protons and in vacuo life tests) has been developed in order to assess the switch behavior in space environment and to achieve a complete evaluation of these optical microswitches for space applications. Little effect has been observed on such devices that may be considered as possible candidates for space applications, at least concerning the mission constraints detailed in this study.
