Shortened MPO optical fiber connector

The invention provides a shortened MPO (Multi-fiber Push On) optical fiber connector, and relates to the technical field of connectors. The shortened MPO optical fiber connector comprises an outer shell and a connector main body, wherein the outer shell is movably sleeved on the connector main body in a front-and-back mode, a stopping boss for limiting backward movement of the outer shell is arranged on the connector main body, a sliding groove is formed in the rear end of the outer shell on the side wall of the outer shell, and the stopping boss is arranged at a position, corresponding to thesliding groove, on the connector main body. According to the shortened MPO optical fiber connector of the invention, through accommodating fitting between the sliding groove and the stopping boss ofthe connector main body, the outer shell can be ensured to move back and forth in the axial direction relative to the connector main body, the sliding groove meets the stroke requirement of the backward movement of the outer s
