摘要： A multifiber optical connector plug capable of realizing low reflection and low insertion loss, without using the refractive index matching material. The multifiber optical connector plug includes a connector plug member made of a plastic material, having a connecting facet on which endfaces of the optical fibers to be connected with other optical fibers are arranged in a transverse direction between the guide pin insertion holes, with the endfaces of the optical fibers projecting out of the connecting facet, the connecting facet being inclined with respect to an axial direction along optical axes of the optical fibers by an angle which is larger than a total reflection critical angle of light beams transmitted through the optical fibers. The connecting facet may have a flat surface shape or a convex ellipsoidal surface shape. A multifiber optical connector can be formed by a pair of such multifiber optical connector plugs with spring member for pressing the multifiber optical connector plugs toward each other in the axial direction and guide pins for aligning the multifiber optical connector plugs.

摘要： The method and associated apparatus of the present invention polishes the front face of a ferrule with first and second slurries such that an end portion of each optical fiber which extends through and is held by the ferrule protrudes beyond the preferentially etched front face of the ferrule by a preselected length. In order to preferentially etch the front face of ferrule as desired, the front face of the ferrule is polished with a first slurry having a plurality of suspended particulates of a first predetermined size on average which initiates the preferential etch of the ferrule relative to the optical fibers. Thereafter, the front face of the ferrule is polished with a second slurry having a plurality of suspended particles of a second predetermined size on average. The slurries are preferably selected such that the second predetermined size is less than the first predetermined size so that the polishing of the front face of the ferrule with the second slurry completes the preferential etch of the ferrule relative to the optical fibers. By preferentially etching the front face of the ferrule relative to the optical fibers, the optical fibers will protrude beyond the front face of the ferrule by a preselected length which does not vary significantly from fiber to fiber.
