The behavior of a chain of sensors based on highly birefringent fibers and operating in two multiplexing configurations was studied as a function of alignment. The analytical relations between alignment at each splice in the chain and the visibility of the interference pattern associated with each sensor were found. These relations make it possible to determine alignment that ensures the desired visibility distributions for sensors along the cascade. In the experimental part of this work, the derived formulas were verified for a few specific chains composed of a limited number of multiplexed sensors.
