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.
Interferometry is an appealing option for vibration sensing because of its simple structure and low cost. This method can be implemented using two inactive single-mode fibers (SMFs).
In this paper, several different categories of SMS fiber structures, including traditional SMS, modified SMS and tapered SMS fiber structures are discussed with some theoretical
