An optical fiber connector assembly includes a first, and second plug connectors, and a socket connector. The first plug connector includes a first main portion and a first plate with a first front surface defining alignment holes. A first distance is defined between the first front surface and the first main portion. The second plug connector includes a second main portion and a second plate with a second front surface. A second distance is defined between the second front surface and the second main portion. The socket connector includes a side surface defining a recess with a bottom surface. A third distance is defined between the side surface and the bottom surface. Alignment pins extend from the bottom surface. The length of each alignment pin is defined as a fourth distance. The third distance is equal to the first distance and greater than sum of the second and fourth distances.
