[0003] In the prior art, an optical transceiver device is usually composed of a light emitting and receiving part, a front-end light-conducting part, and a rear-end transition connection part. Usually, the position of the light-receiving hole is unchanged relative to the front-end light-conducting part, so , during production, it is necessary to adjust the positions of the light-emitting part and the front-end light-conducting part to meet the predetermined coupling power requirements. This requires the operator to manually adjust the three-dimensional position of the light spot, that is, the three-dimensional position of X, Y, and Z. Make it face the position of the light receiving hole, because the diameter of the light spot is very small, and the Z-direction adjustment and alignment is more difficult. Reduced efficiency

Description
Technical field [0001] The invention belongs to the field of optical transceiver devices in an optical fiber communication system. Background technique [0002] Generally speaking, the focal length of the light emitting end is subject to tolerance changes, and its tolerance range is generally ±0.4mm. Therefore, when producing optical transceivers, the light emitted by the light emitting end needs to be focused into a 0.9 micron light spot, and The position of the light receiving hole is adjusted to the position just right for the light spot, and the tolerance range of this position is within ±0.03mm to meet the predetermined coupling power requirement. [0003] In the prior art, the optical transceiver device is usually composed of a light transmitting and receiving part, a front light conducting part, and a back end transition part. Usually, the position of the light receiving hole is constant relative to the front light conducting part, so During production, the positions of the...
