Abstract: PROBLEM TO BE SOLVED: To realize connection with less optical loss by tunning with a connector, in the case of inconsistency on the X, Y and Z axes in a connecting adaptor, in an optical fiber connector to be connected to a back plane/wall. SOLUTION: With the connector end tapered, the inconsistency on the X and Y axes is corrected. Also, by shortening the tip end part, a ferrule is projected beyond the optical plane, dealing with the inconsistency on the Z axis. Further, by attaching a spring part, a ferrule length inside the adaptor is adjustable. Furthermore, a large diameter part is made in barrel assembly to be stored in the housing and a recess is mad in the axis hole of a housing, thereby preventing rotation of the assembly in insertion. Thus, it is possible to connect with the adaptor while optical loss is suppressed.

Abstract: A plug type connector is adapted to be latched to a backplane wall in a fixed position and has a tapered front, noses or connector end for insertion into an adapter which plugs into the backplane wall. The adapter may be misaligned in any or all of the X, Y, Z axes. The tapered nose cams the X or Y misaligned adapter into axial alignment as the adapter and its mount are being inserted. A shortened front or connector end of the connector causes the ferrule of the connector to project beyond the optical plane of the connection so that it reaches a ferrule in a Z aligned adapter to complete the connection. A coil spring within the housing of the connector is tuned to allow counter movement of the ferrule where the ferrule in the adapter is too long, thereby shifting the position of the optical plane. The connector has a ferrule-barrel assembly within a housing and an insert member which has an enlarged diameter portion which is contained by openings in the housing to prevent rotation of the ferrule-barrel assembly
