ABSTRACT:
A method for interconnecting first and second optical fiber bundles (FIG. 4 ), each bundle comprising a plurality of optical fibers, comprises the steps of accurately forming substantially identical matrix arrays of apertures in first and second thin securing plates (FIG. 1, 20, 17). The use of thin plates for the securing plate makes it possible to form apertures by masking and etching with great precision, but the plates themselves have little mechanical strength. The first and second plates are aligned (by balls 24), and a first support member (31), which is mechanically rugged, is simultaneously contacted to the first securing plate (17) and to a first alignment pin (27). The first support member (31) is bonded to the first securing plate while the first securing plate (17) is in alignment with the second securing plate (20). Thereafter, a second support member (29) is simultaneously contacted to the first alignment pin (27) and to the second securing plate (20) and bonded to the second securing plate is it is held in alignment with the first securing plate. Each optical fiber of the first optical fiber bundle is inserted into a first aperture of the first securing plate, and each optical fiber of the second optical fiber bundle is inserted into a first aperture of the second securing plate. After polishing the optical fibers so that they are each in a common plane with a surface of the securing plate to which it is attached, the two securing plates are abutted (FIG. 4). The first (31) and second (29) support members are simultaneously contacted to a common alignment pin (53), thereby to align the first and second securing plates along with the two contained optical fiber bundles (38, 49). By attaching the support members (29, 31) to the two securing plates when they are in alignment, one provides mechanical strength to the two securing plates while assuring that later alignment of the support members aligns the component fiber of the optical fiber bundles.
