ABSTRACT:
An adjustable focus connector with spring action is especially adapted for use with common FC or SAM fiber optic receptacles. The connector includes a ferrule holder which mounts a fiber-carrying ferrule at a distal end thereof. At its proximal end the ferrule holder is threadedly connected to a lead screw member. A thrust collar surrounds the ferrule holder and traps a compression spring in the cavity between the thrust collar and the ferrule holder. Because of appropriate interengagement between the components the ferrule holder cannot rotate relative to the trust collar. A traveler is threadedly connected to the lead screw and abuts against the thrust collar. A connection nut is provided at the distal end of the connector to connect it to the fiber optic receptacle. The spring action of the connector prevents damage to the fiber end during connection of the connector to the fiber optic receptacle.
