Paper Abstract

In-fiber Bragg grating sensors have been used to study mechanical strain in optical fibers that have been terminated in ST connectors. Our findings indicate that terminated sensors experience a compressive strain whose magnitude depends on the cure profile of the epoxy encapsulant used in these connectors. These experiments demonstrate the viability of using in-fiber sensors to characterize fiber optic connector assemblies during and following termination. However, the stain state of the sensing environment is a complex one, so there is the challenge of reading out the correct strain from the sensor response. To address this problem, the T-matrix formalism is being utilized. A review of this method and examples of its use will also be presented.
