The U.S. Navy has embarked on program to develop and install fiber optic (FO) sensors on hull, mechanical, and electrical equipment for control and monitoring purposes. Sensor reliability goals are 100,000 hours mean-time-between-failure (MTBF) and a life time of 40 years. This paper presents results of a study of FO systems and sensors with the goal of estimating reliability and durability in the shipboard environment. Sources of information were technical reports and papers, and direct inputs from manufacturers, developers, and users of FO sensors. Little information was available on reliability tests for individual sensors. The principal components of FO sensors systems, except for fibers and cables, have a MTBF greater than one million hours. Fiber has the lowest MTBF of all the FO sensor components. Results indicate that existing FO sensor components and systems potentially can achieve the required Navy reliability and durability.
