In an embodiment of the present invention, as shown in Fig. 2 the reflecting surface 1171 of spectrophotometric unit 117 and lens 1121 are transmitted
Light (that is, by signal of being entered of the external world) direction between there is an angle, θ, this angle, θ can substantially between 30 and 60 it
Between, to reflect the light (that is, by extraneous signal being entered) being transmitted by lens 1121 to optical receiver 115.Real at some
Apply in example, this angle, θ can be for example between 40 and 50.The first table when the light being transmitted by lens 1121 and substrate 113
When face 1131 is parallel, between the reflecting surface 1171 of spectrophotometric unit 117 and the first surface 1131 of substrate 113, also there is this angle, θ
(essence is between 30 and 60).
Refer to Fig. 4, it is the schematic diagram of an embodiment of Wave guide unit of the present invention.In one embodiment, spectrophotometric unit
117 one end that can be formed at Wave guide unit 116, and form wedge structure, and there is reflecting surface 1171, it is pointed to lens respectively
1121 and through hole 1133, for reflection by lens 1121 light (that is, entered signal) by the external world to optical receiver
115.In this embodiment, the length of Wave guide unit 116 can be substantially equal to optical transmitting set 114 and spectrophotometric unit 117 (or through hole
The distance between 1133).
Refer to Fig. 5, it is the schematic diagram of an embodiment of optical transceiver module of the present invention.In one embodiment, also may be used
Omit setting Wave guide unit 116 in optical transceiver module 110, that is, the light that optical transmitting set 114 is sent is direct arrival
Spectrophotometric unit 217, and without Wave guide unit 116.In this embodiment, spectrophotometric unit 217 may be, for example, optical filter, light splitting
Mirror, diffractive optical element (DOE), wavelength separated multiplexer (wavelength division multiplexer, WDM), around
Penetrate grating or other have the assembly of light splitting function.
Refer to Fig. 6, it is the schematic diagram of an embodiment of optical transceiver module of the present invention.In one embodiment, carry
Pedestal 311 can parallel to substrate 113, and using support column 118 come bearing substrate 113 on bearing base 311, thus can be formed
Multilayer encapsulation structure.Because substrate 113 is abreast to be arranged on bearing base 311, therefore substrate 113 can more securely be packaged in
In optical transceiver module 110.And because substrate 113 is to be stacked on bearing base 311, thus it is more beneficial for optical transceiver module
110 processing procedure.In this embodiment, on the second surface 1132 that optical receiver 115 may be selected be arranged at substrate 113 or carry base
On the surface of seat 311, and it is pointed to the through hole 1133 of substrate 113.
Additionally, as shown in fig. 6, in this embodiment, the lens 3121 of upper lid 112 can be pointed to the through hole of substrate 113
1133 top so that lens 3121 major axis can parallel to substrate 113, and the opening of the V-shaped groove of spectrophotometric unit 317 can faced by
In through hole 1133.In this embodiment, spectrophotometric unit 317 can reflect the light that optical transmitting set 114 sent to lens 3121, and
Light (signal) outside allowing is by spectrophotometric unit 317 so that the light of outside can be passed by the through hole 1133 of substrate 113
To optical receiver 115.
The optical transceiver module of the present invention can achieve two-way communication, and can be greatly reduced not expected in optical transceiver module
Noise (veiling glare) disturbs, to guarantee the quality of two-way communication.
