A new approach for multiplexing interferometric fiber optic sensors is described and studied. The approach is based on a lattice of unbalanced Mach-Zehnder Interferometers (MZI). This configuration is inherently low-loss as a result of the fully serial connection, and can be implemented and deployed in a simple manner. The signals from the cascaded sensors are extracted from the measured data via a layer peeling algorithm. Prior and during the work on the described implementation simulations have been held. The target of the simulations is to test the layer peeling algorithm and its robustness, thus drawing the limitations of the multiplexing configuration performance. The implementation that is chosen for this work is polarimetric, using high birefringence (HiBi) fibers as sensors and interferometers. The interrogation method chosen is sweeping with a continuous wave (CW) over a range of optical frequencies, although other methods are theoretically feasible. A fifth order polarimetric implementation of the proposed multiplexing technique has been constructed and characterized. The third sensor is buried in a sandbox while the rest of the sensors are spooled on a bobbin. The system successfully separated and monitored the pressure variations in the different sensors.
