Abstract
A core-stiffed composite structure includes a plurality of bonded layers forming the core-stiffened composite structure, a fiber optic conductor embedded between two of the plurality of bonded layers, the fiber optic conductor including a terminal end, and a protective box embedded in the core-stiffened composite structure and bonded to one or more of the plurality of bonded layers, wherein the terminal end of the fiber optic conductor projects into the protective box.
Claims3
A core-stiffened composite structure comprising:
- a plurality of bonded layers forming the core-stiffened composite structure;
- a fiber optic conductor embedded between two of the plurality of bonded layers, the fiber optic conductor including a terminal end;
- a protective box embedded in the core-stiffened composite structure and bonded to one or more of the plurality of bonded layers, the protective box including a base wall and a side wall that form a connector receiving zone, at least one of the base wall and the side wall including an opening through which passes the terminal end of the fiber optic conductor into the connector receiving zone wherein the terminal end of the fiber optic conductor projects into the protective box;
- and
- a protective box cover extending over the connector receiving zone and connected with one of the side wall and the base wall, the protective box cover including an external surface that is substantially co-planar with the core-stiffened composite structure, wherein the protective box cover includes a plurality of openings that register with the plurality of openings in the side wall.

A core-stiffened composite structure comprising:
- a plurality of bonded layers forming the core-stiffened composite structure;
- a fiber optic conductor embedded between two of the plurality of bonded layers, the fiber optic conductor including a terminal end;
- and
- a protective box embedded in the core-stiffened composite structure and bonded to one or more of the plurality of bonded layers, the protective box including a base wall and a side wall that form a connector receiving zone, at least one of the base wall and the side wall including an opening through which passes the terminal end of the fiber optic conductor into the connector receiving zone, wherein the terminal end of the fiber optic conductor projects into the protective box;
- a protective box cover extending over the connector receiving zone and connected with one of the side wall and the base wall, the protective box cover including at least one surface that projected proudly of and is at a non-zero angle relative to, the structure, the at least one surface having a connector outlet that is coupled to the fiber optic connector;
- and
- a fiber optic connector arranged in the connector receiving zone and operatively coupled to the terminal end of the fiber optic conductor, wherein the protective box cover includes a side surface and a fastener surface, the side surface defining the at least one surface at the non-zero angle and the fastener surface extending substantially parallel to and spaced from an external surface of the core-stiffened composite structure.
