Abstract: A fiber optic cable assembly includes a fiber optic cable, a tether, and an overmold. The fiber optic cable includes an optical fiber, a strength member, and a jacket, where the jacket includes an interior portion contacting the strength member and an exterior portion adjoining the interior portion. The interior and exterior portions of the jacket both include polyethylene, and the exterior portion further includes an additive that is not in the interior portion. The tether is coupled to the fiber optic cable at an attachment point. The optical fiber or another optical fiber spliced to the optical fiber, diverges from the fiber optic cable via the tether. The overmold encloses the attachment point and is attached directly to a discrete section of the exterior portion of the jacket proximate to the attachment point. The additive facilitates bonding of the overmold to the discrete section.
