Abstract: An aeronautical composite structure configured to monitor a physical status of a bonded portion between structural components using a multi-core optical fiber. A method and system for monitoring the physical status of a bonded portion in an aeronautical composite structure also uses a multi-core optical fiber. More particularly, the invention relates to a structure and method for monitoring the physical status of a bonded portion of an aeronautical composite structure from its manufacturing to its use in flight using a multi-core optical fiber.

Abstract: An optical fiber connection device comprising a prism, first and second connection elements, inner and outer ferrules and an elastic element. The prism has an inner conduit ending in a first bore configured to receive an input optical fiber, and in a second bore configured to receive the first connection element, which, in turn, is configured to receive the second connection element. This second connection element is also configured to receive an output optical fiber. The conduit comprises two sections forming a ramp to lead the input optical fiber towards the fibers connection. The first connection element has an inner box, and the second connection element has an outer protrusion to provide a unique connecting position. The inner and outer ferrules, and the elastic element are retained in the second connection element.
