<p>A connector (5) for positioning an optical fiber (35) featuring a rotatable locking ring (9) having a cam shaped inner wall, having in circumferential succession a first (25), second (26) and third (27) inner diameter, the third inner diameter (27) being smaller than the first inner diameter (25) and the second inner diameter (26) being smaller than the third inner diameter. Rotation of the locking ring applies inward radial compression to centering elements (16,24) as the locking ring is rotated from the first to second inner diameter position and to a closed position when the area of the third inner diameter is reached. A plurality of centering members is provided, at least one (24) having no resilient coating thereon whereby compression forces an optical fiber (35) against resilient material (18,23), thereby centering the optical fiber and giving the fiber additional strength to withstand longitudinal tensional forces. Also disclosed is an end grommet sized to allow watertight insertion of a buffer tube.</p> |
