As fiber optic systems are integrated into missile and space platforms, a growing need emerges for fiber optic switches capable of withstanding and operating in severe environments. Present commercial devices do not meet the stringent requirements for missile or space environments, nor are they always available in the required configuration. This paper explores some of the design considerations for a single-mode fiber optic crossbar switch for harsh environments. Some possible implementations of switching elements are described, and the design features of the chosen switch implementation are also described. Loss mechanisms for the switch are discussed, and test results are given for the sleeted design.
