Abstract
In this work we demonstrate the multiplexing capability of new optical fiber Fabry-Perot interferometers based on airmicrocavities
using a commercial FBG interrogator. Three optimized air-microcavity interferometer sensors have been
multiplexed in a single network and have been monitored using the commercial FBGs interrogator in combination with
FFT calculations. Results show a sensitivity of 2.18 π rad/mε and a crosstalk-free operation.
