Abstract
A system of making high density optical fiber arrays that includes securing the optical fiber ends in the housing front mask openings, then lapping the fiber ends and front mask forward surface to angle the fiber end front surfaces so that reflected wave energy does not interfere with optical signal data when transmitted during use. The opening pattern is preferably 2×2 to 128×128 or higher. Several alternate lap tool designs are disclosed including translational and rotating laps formed from solid bodies or a series of stacked plates. Standard slurry grinding and polishing compounds can be applied as desired. If a layer of epoxy originally covers the mask front face, it is removed by the lap tool as the fiber ends are lapped.
