An optical transceiver which is inserted and ejected with respect to a cage is disclosed. The optical transceiver comprises a slider, a housing supporting the slider to slid the slider along the first direction, and a latch rotating along a second direction intersecting with the first direction at the center of a shaft. The latch has a first face engaging the cage and a second face locking the slider, and is supported by the housing. The latch controls the rotating by locking the second face to the slider when the slider is in a first position, and uncontrols the rotating when the slider is in a second position farther than the first position ejected a direction. A position of the shaft is the same position as a position of the first face or more than a position ejected in case of locking the second face to the slider.
