A duplex fiber optic connector plug includes at least one fiber optic connector, a first casing, a second casing and a release lever. The release lever is axially coupled to a surface of the first casing and has an end coupled to a release bracket of the fiber optic connector to form a seesaw design. During operation, the release lever is compressed by the force of the finger, so that an end of the release lever is elevated, and the other end compresses the release bracket downward to release from a fiber optic socket, so as to provide an intuitively convenient operation and improve the convenience of use.
