  • Connector for optical fibers
    Patent number: 6250818
    Abstract: A connector for optical fibers. A coupler is designed to affix an optical component. A cable mounting structure is designed to retain an optical cable, and to retain a terminating ferrule in an optical alignment with the optical component. A distance between a front face of the termination ferrule and a tail end of the cable mounting structure is about 1.648″. An adjuster bears threads mating to threads of the cable mounting structure. The adjuster is coupled in a fixed axial relationship with the coupler. An axial relative displacement between the cable mounting structure and the optical component is adjustable by relative rotation of the cable mounting structure and adjuster. The length of the adjuster is about 0.415″. The cable mounting structure bears a shoulder unitarily formed with a threaded component of the cable mounting structure effective as a limit stop of to limit relative movement of the adjuster.
