Efficient use of expensive components of optic vibration sensor

This paper studies possible utilization of fiber optic switches for more efficient utilization of expensive electronic components which are the core of long range fiber-based sensors systems. Complex architecture of such systems starting to be used for monitoring of events along various linear objects like railway lines, product lines or object defense perimeters, are based on rather expensive ultra narrow band laser source and interrogation electronics. Possible sharing of these expensive components for sensing on more fiber optic lines is discussed in this work.
