A method for measuring the optical fiber hole insert using the apparatus is also provided.

A method of securing an optical fiber to a ferrule includes: heating an adhesive composition that is disposed within the ferrule to melt the adhesive composition; inserting the optical fiber into a fiber-receiving passage defining an inner surface of the ferrule and into contact with the melted adhesive composition; and cooling the melted adhesive composition. The adhesive composition is a solid material disposed within the fiber-receiving passage of the ferrule and in contact with the inner surface of the ferrule prior to the heating step. Additionally, the adhesive composition comprises a partially cross-linked resin and a coupling agent that covalently bonds the partially cross-linked resin to respective inorganic surfaces of the optical fiber and the ferrule following the cooling step.

A ferrule mold having a reverse-image of a through-hole array for optical fibers is formed. A non-polymeric ferrule material is deposited in the reverse-image mold, followed by removing the mold to create a multi-fiber connector ferrule having at least two fiber through-holes. An optical fiber is inserted in each through-hole until each fiber endface is positioned approximately even with a connection surface of the ferrule. A fiber recess for each of the optical fibers is formed such that each fiber is recessed from the multi-fiber ferrule connection surface by a distance of at least 0.1 micron. The recess may be formed by differential polishing of the non-polymeric ferrule and endfaces of the optical fibers. Alternatively, a layer of spacer material may be deposited over the multi-fiber ferrule connection surface. An antireflection coating is deposited over the ends of the recessed fibers.
