Abstract:
An optical transceiver module comprising a body and an optical transceiver unit; the focus of the optical transceiver unit being calibrated by proprietary tools and then being combined with the body; the optical transceiver unit having a retaining seat, and a light receiving or emitting module coaxially arranged within the retaining seat; characterized in that:the body includes a mini head cover, a seat, and a tubular sleeve; wherein the mini head cover is made of ceramic material and has a front surface and a rear surface which are opposite to one another; an axial hole extends between the front surface and rear surface for receiving an optical fiber so that light is coupled to the axial central tube of the optical fiber; a rear surface is an inclined plane for preventing reflecting light from radiating to a laser diode so that the laser diode is interfered; the seat is made of metal material; a front surface is opposite to the rear surface; a front surface has an annular hole for receiving the mini head cover; a bottom of the annular hole is an inclined plane corresponding to the rear surface; an interior of the annular hole has a recess; thereby, glue is filled into a slot, thereby, the mini head cover being fixed to the seat; the rear surface has a hole which is communicated to the annular hole; light passes through the annular hole; and the tubular sleeve is made of metal material; an internal thereof has an inserting hole for being inserted by a joint of the optical fiber for transmission light.
