A straight SMS fibre structure can be used as a displacement sensor by applying strain along the fibre axis and hence has the potential to be used as a sensor for mechanical vibrations.
It can convert every 1 meter of fiber into a fiber microphone sensor, capable of capturing and demodulating sound vibrations at any position along the fiber. It

By using a digital oscilloscope, we recorded and analysed the vibrating signals obtained from the SMS fiber structure as well as from a GS-32CT geophone for referencing.
Recently, all-fiber vibration sensors have been proposed using single mode-multimode-single mode (SMS) fiber structures that required the 2016, 33 rd NATIONAL RADIO SCIENCE
Interest is growing in the use of telecom fiber networks for sensing purposes. Notably, vibration sensing has the potential not only for network health monitoring but also for generating new revenue sources.
