Abstract: A housing for fiber optic components reduces stress on optical fibers and protects the components from environmental shock and vibration. The housing includes a protective body having a receiving space wherein the fiber optic component is positioned. A rigid adhesive applied to the fibers in a specific stress reducing profile near the ends of the receiving space secures the component out of contact with the wall of the receiving space without inducing stress on the jacketless optical fibers. A gel support material fills the receiving space surrounding the component and providing vibration isolation. The invention is particularly uses for housing fiber optic couplers which are subject to shock, vibration, and temperature extremes.

Abstract: A fiber optic coupler includes at least two optical fibers having a coupled region and at least one lead portion extending therefrom. The optical fibers have a protective jacket thereon. The protective jacket is removed from the coupled region and from a region of the at least one lead portion adjacent the coupled region resulting in a jacketless coupled region, at least one jacketless lead portion and at least one jacketed lead portion. The fiber optic coupler further includes a protective body having a receiving space therein for receiving the coupled region. The protective body has at least one entrance from which said jacketed lead portion emerges. A rejacket material at least partially surrounds a length of the jacketless lead portion adjacent the jacketed lead portion resulting in a rejacketed lead portion.
