Connector system for a single optical fiber

摘要

A connector system for coupling a pair of single optical fibers is disclosed. The connector comprises a connector tube, a lens spacer, a pair of positioning sleeves and positioning sleeve elastomeric stoppers, a pair of adjusting screws and a pair of clamping screws with corresponding clamping screw elastomeric stoppers. The optical fibers to be connected are cut and flame treated to form hemispherical beads or lenses on each cut end. The optical fiber lenses are spaced apart inside the connector surrounded by a coupling medium that has an index of refraction higher than the optical fibers. The fibers are optically aligned by fine adjustments such that a maximum strength is obtained.
