摘要

•A temperature-insensitive quasi-distributed high-pressure test system is proposed.•A quasi-distributed fiber-optic sensor formed by PCF based EFPI units is demonstrated.•Microwave interference system for spectral reconstruction of cascaded FPI units is achieved.•Spectral results gotten by microwave interference system follows results based on OSA.
