ABSTRACT:
A strain relief apparatus for use with at least one optical fiber mounted between plies within a matrix of a generally planar laminated composite structure wherein the fiber extends from a surface of the composite structure. The apparatus has an anchor that has a distal portion, a proximal portion and an orifice extending therethrough, wherein the proximal portion is configured to be embedded within the composite structure with the distal portion extending from the composite structure and the optical fiber extending through the orifice. In one embodiment, protective cabling is adapted to be threaded over the optical fiber and the protective cabling is secured to the distal anchor portion to provide strain relief to the optical fiber. In another embodiment, a ferrule is adopted to extend over the optical fiber and is mounted within the distal anchor portion to protect the optical fiber. In another embodiment, the anchor is designed such that the orifice increases in size to form a bend radius that provides strain relief to the fiber.
