<p>FIBER OPTIC CONNECTOR HAVING DUAL SUPPORTING SURFACES AND METHOD OF TERMINATING FIBER OPTIC TRANSMISSION MEMBERS A fiber optic connector comprises a housing member, ferrule members and a coupling member. The housing member is rigid and has a profiled bore extending therethrough which has a central cylindrical surface, tapered surfaces on each side of the central cylindrical surface, and a support surface at the outer end of each tapered surface. The ferrule members are of resilient deformable material and are terminated onto fiber optic transmission members. Each ferrule member has a profiled front end comprising a front cylindrical section of slightly larger diameter than the central cylindrical surface, tapered sections slightly smaller than the bore tapered surfaces, and an alignment section for tight engagement with the support surfaces when the ferrule members are urged together by the coupling member, thereby applying a radial compressive force to the front cylindrical sections and axially aligning the fiber optic transmission members and the alignment sections of the ferrule members tightly engaging the support surfaces of the housing member to maintain the ferrule members in alignment when lateral forces are applied to the ferrule members. A reservoir for index-matching fluid is formed by peripheral surfaces around the engaged front surfaces of the ferrule members. A ferrule member may be formed with a domed front surface which is polished to a flat front surface after terminating an end of a fiber optic transmission member therein.</p> |
