New Description: [New Technology Field] This creation relates to a socket structure for optical transceiver modules, which can reduce the loss of incident optical signal and reduce the production cost by the integrated optical fiber holding member. [Prior Art] In optical fiber communication systems, Optical Sub-Assembly for Transceivers is an important medium for optical signal and electrical signal conversion. The optical transceiver module can be divided into optical transmission times for transmitting optical signals. Transmitting Optical Sub-Assembly (TOSA); a bidirectional optical sub-assembly (BOSA) that can accommodate both directions of information in the same optical fiber; and can simultaneously receive digital signals and analog signals. Types such as Tri-direetion Optical Sub-Assembly (TRI-DI OSA) that transmit digital signals. The TOSA, BOSA, and TRI-DIOSA have a socket structure for the fiber optic connector to be inserted and form a coupling coupling for transmitting optical signals.

An optical fiber 15 is disposed inside the head cover 14. The bottom surface of the head cover 14 is provided with a slope 16 ′ to prevent the reflected light source from entering the light-emitting element π, so that the light-emitting element is disturbed by noise. As shown in Fig. 1B, in terms of geometric optics theory, the beam exit angle is calculated as 3 M426038, where iiSIN(0 1)=SIN(0 1+0 2) ' n : fiber refractive index, 0 1: fiber in the headgear The grinding angle of the end face, 02 · The angle between the fiber axis and the light exit direction. By using the formula and the theory that light is incident on the optical fiber and the light exits from the optical fiber (ie, the light incident angle and the light exit angle 02) is the same as the axial direction, the head cover 14 is disposed in the susceptor 12 in an upright manner. Therefore, the incident direction of the optical signal of the light-emitting element 17 is in line with the optical fiber 15 without being emitted in the same axial direction as the outgoing light of the optical fiber 15, thereby causing loss of the incident optical signal, and this deficiency needs to be remedied. [New content] The main purpose of this creation is to provide a socket structure that can reduce the loss of incident light signals and significantly reduce production costs.

The first receiving hole 22 is located at the front end of the receiving tube and has a larger diameter than the second receiving hole 23. The second receiving hole 23 has a larger diameter than the connecting hole 24, and the connecting hole 24 is located at the rear end of the receiving tube 21. As shown in FIG. 5, the optical fiber holder 3 has a dielectric portion 31 and an inclined head 32. The interfacial portion 31 defines a third receiving aperture % sized to receive a portion of the length of the sleeve 40, and - a fourth receiving aperture 34 for receiving a portion of the length of the head covering 50. The tilting head 32 defines a tilting hole 35 and a transition region 39 communicating with the tilting hole %, and the sin is close to the fifth receiving hole 34, and the diameter is sized to receive the rigid end (inclined) portion of the optical fiber 54 and The illuminating signal of the illuminating element is coupled to the fiber Μ. The transition zone 39 allows the fiber 54 to be tapered such that the fiber 54 can be slowly turned in the transition zone 39 as it is inserted from the angled aperture 35, resulting in a larger bend radius. The tilting head 32 is formed with a first M426038 and a second annular shoulder 36, 37. The front end surface of the tilting head 32 is a beveled surface 38, which prevents reflected light from directly entering the light emitting element, causing the light emitting element to be disturbed by noise.
