Abstract

This paper reports the performance of low-profile multi-fiber connectors between sensor-embedded composite panels. The interconnection of such composite panels has been cited as a major limitation to optical fiber sensor- embedded `smart materials and structures' during the past fourteen years. Typically the leads of optical fiber sensors embedded in composites have been brought out of the material either at the sides through protective tubing or through the surface via standard connectors in recessed depressions in the material surface. The first of these options suffers from a lack of mechanical robustness, while the second serves to locally weaken the material and to expose the fiber sensor channel to the external environment. We report successful connector embedment at the panel edge with singlemode connector losses of less than 1.1 dB, and connectorized fiber sensors accessed through the fiber connector.
