A fiber optic device comprising: a housing, the housing defining a chamber in which an active element of the device is disposed, the housing having a wall with an aperture therein, an optical fiber feedthrough assembly having a fiber optic cable attached within and to a sleeve, a portion of the sleeve extending through the aperture in the housing to dispose a first end of the fiber within the chamber, a bushing for attaching the sleeve to the wall of the housing at a first, proximal, location and a washer for attaching the sleeve to the wall of the housing at second, distal, location, the proximal and distal locations being offset from each other by a predetermined offset distance, both of the locations lying along the axis of the sleeve such that when so attached the first end of the fiber lies in an operative relationship to the active element, the wall of the housing, the bushing, and the washer and the attachments therebetween cooperating to define a joint assembly having a predetermined flexibility associated therewith, a support abutment for supporting the feedthrough assembly at a predetermined point of support, the point of support of the feedthrough assembly and the distal attachment locaton being spaced by a predetermined span therebetween, and means disposed on the feedthrough assembly intermediate the first end of the fiber and the point of support of the feedthrough assembly for isolating the first end of the fiber from the effects of a deflection imposed on the feedthrough assembly.
