<p>A fiber optic connector comprises a housing member (58), ferrule members (10) and a coupling member (72). The housing member (58) is rigid and has a profiled bore (56) extending therethrough which has a central cylindrical surface (60), tapered surfaces (62) on each side of the central cylindrical surface (60), and a support surface (64) at the outer end of each tapered surface (62). The ferrule members (10) are of resilient deformable material and are terminated onto fiber optic transmission members. Each ferrule member (10) has a profiled front end comprising a front cylindrical section (20) of slightly larger diameter than the central cylindrical surface (60), a tapered section (22) slightly smaller than the bore tapered surfaces (62), and an alignment section (24) for tight engagement with the support surfaces (64) when the ferrule members (10) are urged together by coupling member (72) thereby applying a radial compressive force to the front cylindrical sections (20) and axially aligning the fiber optic transmission members (14) and the alignment sections of the ferrule members (10) tightly engaging the support surfaces (64) of the housing member (58) to maintain the ferrule members (10) in alignment when lateral forces are applied to the ferrule members (10). A reservoir for index-matching fluid is formed peripherally around the engaged front surfaces (35) by peripheral surfaces (52). A ferrule member (10) may be formed with a domed front surface (34) which is polished to a flat front surface (35) after terminating an end of a fiber optic transmission member (14) therein.</p> |
