A retractable optical fiber assembly is provided, including a first ring adapted to accommodate a first winding of a fiber optic cable having a first end. A second ring is positioned concentrically with the first ring. The second ring is rotatable with respect to the first ring, and the second ring is adapted to accommodate a second winding of the fiber optic cable having a second end. Rotating the second ring in a first direction causes the fiber optic cable to wind onto the second ring thereby retracting the second end towards the retractable optical fiber assembly, and causes the fiber optic cable to unwind about the first ring thereby retaining the first end in a stable position as the second end is retracted. A module is also provided that includes a plurality of retractable optical fiber assemblies.
