Sensor arrays for multiplexing multimode fiber-based intensity modulated sensors may be constructed in the form of a ladder structure employing 2 X 2 optical fiber couplers. The input/output relationship of a multimode fiber diffused coupler is dependent on the launch conditions of light. The degree of uncertainty between the input/output relationship of a coupler, as a result of the highly unequal split ratio and the state of modal equilibrium in the launched light, is investigated. The power penalties due to this phenomenon are calculated and an optimum solution for multimode fiber-based sensor array design is derived.
