A sleeve (Sleeve) 13 is coaxially disposed. In the accommodating tube 11 and the susceptor 12, η, and a ferrule stub 14 are coaxially disposed in the susceptor 12 and the sleeve tube 13. An optical fiber 15 is disposed inside the 兮-* Π ' s head cover 14. The bottom surface of the head cover 14 is provided with an oblique surface; the needle surface 16 prevents the reflective light source from entering the light-emitting element 1 7 ', causing the light-emitting element to be subjected to the interference of the noise _ as shown in FIG. 1B, in terms of geometric optical theory, The central striker's angle is calculated as nSIN(<9 1)=SIN(6» 1 + 6>2), η: fiber refraction 娈, 0 1: fiber is ground in the head 3 M419933 Angle ' Θ 2 : The cool angle of 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 direction of the optical signal of the light-emitting element 17 is linear with the optical fiber 15, and the light emitted from the optical fiber 15 and the optical fiber 15 are emitted in the same axial direction, thereby causing loss of the incident optical number. This deficiency needs to be remedied. [New content] The main purpose of this creation is to provide a socket structure for an optical transceiver module that can improve the light efficiency without changing the incident direction of the light-emitting element. The socket structure for the optical transceiver module includes a receiving tube; a base is coaxially disposed in the receiving tube, and has a first head cover receiving hole, and a second head cover inclined receiving hole-sleeve tube, coaxially disposed on the base a first hood, coaxially disposed in the first hood receiving hole of the base; a second hood coupled to the second hood of the pedestal, the accommodating hole, and the optical fiber coupled to the _ The inner portion of the second hood is disposed in the pedestal in an inclined manner by the second hood, and the direction for the bridge light is emitted in the same axial direction as the illuminating signal of the illuminating element, so that the illuminating signal reduces the loss at the time of incidence.

The first receiving hole 22 is located at the lower end of the receiving tube, and the size of the straight melon is larger than the second receiving hole 23. The second receiving aperture has a larger diameter than the central aperture 24. - Figure 5 shows an example of the base 3〇. The inside of the base 3 has a sleeve receiving hole, which can be used to receive the sleeve 4''. The first head cover receiving hole can be used to receive the first hole. The first hole can be used to receive the first member. The ahai-headgear 6〇 is placed in the base in an inclined manner. Fig. 6 shows an example of the sleeve tube 40, and the inside of the sleeve tube 4 has a through hole 41 for receiving the first head cover $ 〇. An example of the first head & turn 50. The first head cover 5 has an upper 'lower (four) 51 '52' in the opposite direction and the fiber optic jack 53 extends axially between the upper 'lower portions 51, 52. 5 M419933 FIG. 8 shows the second head cover 6 of the second head cover 6 (the upper and lower portions 61, 62' having opposite directions and a fiber insertion hole 63 extending axially between the upper and lower P 61 62. The lower portion 62 of the s-hai is a sloped surface, which prevents the reflected light from directly entering the light-emitting element, so that the light-emitting element is interfered by the noise. The optical fiber sockets 53 and 63 of the X head cover 50 and the first head cover 60 are fixed with an optical fiber. 54, so that the illuminating signal of the illuminating element is coupled to the optical fiber 54. Since the second hood 60 is disposed in an inclined manner In the two-head sleeve accommodating hole 33, the light emission direction and the incident direction of the light are in the same axial direction to satisfy the calculation formula of the beam exit angle, so that the light signal emitted by the light-emitting element 7 能 can be aggregated 5 to the first hood. The optical fiber 54 is used to reduce the shank loss to greatly question the coupling efficiency. As shown in FIG. 9 , the second hood 6 〇 is tilted by Θ 2 angle to correct the light exiting direction and illuminating of the second hood 60 . The illuminating signal of the component 70 is incident in the same axial direction to obtain the best coupling efficiency.
