[Prior Art] Optical fiber network communication refers to a transmission method in which light signals are transmitted from a signal transmitting end to a signal receiving end in the form of light waves by conversion between optical and electrical signals. In order to convert the electrical signal into an optical signal or convert the optical signal into an electrical signal, an optical transceiver module is disposed at the end of the optical fiber medium, and the optical transceiver module respectively includes a signal for converting the electrical signal into an optical signal. The emitted light emitting sub-module and a light receiving sub-module for receiving the optical signal and converting it into an electrical signal. Generally, the optical transmitting component used in the optical fiber network communication is the laser diode 1 plus, as the laser is used for laying the yarn, the directionality is strong, usually with the single mode fiber. Light and effective village up to 50%. The narrower (four) spectrum also helps to increase the transmission rate and reduce the modal dispersion (m〇deldispersi〇n). The light-receiving element, usually a photodiode (the diopter), is converted into a woven fabric, such as a junction diode, a P_1_n: a polar body, or an avalanche diode. . In the prior art, the light emitting sub-module and the light receiving sub-module are disposed on a rigid printed circuit board and coupled to the printing circuit board by a light steering device, so that the optical signal can be borrowed.

In the calibration fashion, an optical correction instrument is required to make the plurality of lenses on the light steering device be divided into M442520. The optical transmission component and the light receiving component are not accurately aligned. Since the optical calibration instrument is very expensive, and the general assembly factory does not have the technology for correcting the optical steering device, the mass production and the division of labor are assembled. inconvenient. In addition, since the copper foil disposed on the hard printed circuit board cannot be assembled, the finished product of the product is too large to effectively save space. If a flexible printed circuit board is used as the circuit substrate, the copper foil density can be increased. However, due to the nature of the material, the flexible printed circuit board has a problem of insufficient fixing force of the light receiving element disposed thereon, which may cause the lateral force of the plugging and unplugging after being inserted and removed a plurality of times. The light receiving component is loosened or detached from the flexible printed circuit board, and the optical transceiver module disposed on the flexible printed circuit board is offset, and the light transmitting component and the light receiving component are out of focus with the lens. The problem of poor yield is created. [New content] The main purpose of this creation is to combine the optical steering device and the optical transceiver module in a modular form to design an optical transceiver with a structure that enhances the fixing force between the substrate and the optical transceiver module.
