Abstract: An apparatus includes a strain relief formed in helical shape and formed with a U-shaped channel. The strain relief can be used around a cable of a component or a spool extension of a fiber tray.

Abstract: A multicore fiber optic cable comprising of a central fiber having a central fiber outer diameter, a central fiber coating surrounding the central fiber outer diameter of the central fiber, the central fiber coating having a continuous spiraled groove around the central fiber outer diameter, a dual core optical fiber having a dual core optical fiber geometry, the dual core optical fiber spiraled around the central fiber coating and disposed within the spiraled groove such that the dual core optical fiber is wound around the central fiber coating in a spiral pattern and the central fiber core geometry and the dual core optical fiber geometry are oriented longitudinally to negate link path length difference; and an outer sheath surrounding the central fiber coating and the dual core optical fiber.
