CA 2606657

Fiber optic sensors commonly require a 180 degree turnaround to form a continuous optical circuit. Methods and apparatus for providing 180 degree turnarounds in a fiber optic system that include a shorter radius turnaround then provided by micro-bending the optic fiber are desired. An embodiment of a turnaround apparatus includes a first optic fiber pigtail, a second optic fiber pigtail, and an optical waveguide forming a U-shaped path having an input end optically connected to a first end of the first pigtail and an output end optically connected to a first end of the second pigtail.
