Abstract
A new, neutral gender MT-type connector ferrule and adapter are being disclosed. The ferrule consists of a body with a number of optical fiber channels and two, not removable, guide pins. The ferrule does not have a male/female configuration. In our invention, the guiding pins are fixed to the ferrule body and located in the recessed portion of the body in such a way that they do not protrude beyond the face (contact surface) of the fibers. This design has several advantages over the standard MT-type ferrule. The new ferrule is easier to terminate, easier and less expensive to produce and improves the optical performance of the connection by increasing the positioning accuracy of the mating fibers. Connector systems based on this new ferrule design need a novel mating adapter. The design of this adapter is shown in this invention. The new adapter has V-grooves to hold, under pressure, the guiding pins of the ferrules. This zero-gap design contributes to the higher performance of the system. The ferrule alignment pins are used as a datum to perform proper polishing procedure.
