TechConnect Innovation Program

Polarization preserving fiber optic rotary joint

National Radio Astronomy Observatory, NM, United States

TECHNOLOGY SUMMARY

A mechanical device that minimizes the change in fiber optic signal polarization through a +/- 300 degree rotating joint.

Primary Application Area: Defense & Transportation

Technology Development Status: Proven Manufacturability

Technology Readiness Level: TRL 9

FIGURES OF MERIT

Value Proposition: When polarization is critical in data transport, or highly desirable, when passing through fiber optic cable bends that can change frequently, this innovation prevents the need for recalibration as it preserves polarization orientation before, during and after movement of the cables.
