A latch type optical communication module is easily mounted to and detached from a system port having a cage by means of a latch. The optical communication module is provided with a latch. The latch is rotated around a hinge shaft fixed to both sides of a receptacle and engaging latch holes of ends of the latch. When rotated the latch moves latch drivers to force a slider upward, the slider raises a groove engaging a fixing tap of the optical communication module thereby allowing the optical communication module to be detached from the system port. The optical communication module can be detached from the system port without a tool or influence or adjacent an optical communication module.
