An alignment bushing (40) having a frusto-conical entranceway (44,46) at each of its opposite end faces (41,43) with each entranceway receiving a frusto-conical lens (30) terminted to an optical fiber cable (16,26), the bushing optically aligning and coupling an optical signal passed between a fiber in each with each lens having its focal point (31) coaxially rearward of a hemispherical nose portion of the lens and abutting the fiber end. The frusto-conical cross-section defining the entranceway and lens conform identically to assure coaxial seating.
