An adapter holds a multi-fiber ferrule in position to mate with a multi-fiber ferrule in a fiber optic connector. The adapter includes an adapter body that has a first opening in a first side of the adapter body that receives the multi-fiber ferrule and a second opening in the second side of the adapter body to removably receive the fiber optic connector. The adapter also includes a pair of latches connected to the adapter and disposed adjacent the first opening to engage and hold the multi-fiber ferrule in the adapter. The pair of latches are connected to the adapter body along longer edges of the first opening and extend in a direction away from the first and the second openings, the pair of latches having a terminal end and a non-uniform thickness between the adapter body and terminal ends.
