Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.

What is claimed is: 1. A process comprising: positioning an insert within a housing, wherein the insert holds a plurality of optical fiber ends and wherein the housing has two or more solder pins projecting therefrom; positioning a frame on the housing such that the solder pins are received in a corresponding number of holes in the frame, wherein the frame surrounds a lens plate that includes a plurality of individual lenses; emitting light from one or more of the plurality of fiber ends through one or more corresponding individual lenses; reflecting the emitted light back through one or more of the individual lenses into one or more corresponding fiber ends; aligning the frame by moving it parallel and perpendicular to the solder pins until the light reflected into the fiber ends is maximized; and fixing the position of the frame relative to the housing by soldering the solder pins within the holes. 2. The process of claim 1 wherein reflecting the emitted light back through one or more of the individual lenses into one or more corresponding fiber ends comprises placing a mirror at a pre-determined focal plane of the lens plate. 3. The process of claim 1 further comprising inserting a glass plate between the output face and the lens plate. 4. process of claim 3 wherein an air gap remains between the glass plate and the lens plate. 5. The process of claim 1 wherein the solder pins project out from an end face of the housing. 6. The process of claim 1 wherein soldering the solder pins within the holes comprises depositing solder in the portions of the holes not occupied by the solder pins.
