The technical solution for applying example offer places transmitting-receiving optical secondary module.
Specifically, a kind of transmitting-receiving optical secondary module used in the embodiment of the present invention has and adopts the following technical scheme that：
A kind of transmitting-receiving optical secondary module used in the embodiment of the present invention is specifically described below, referring to Fig. 4, it is wrapped
It includes：
The side of transmitting terminal 1, light splitting piece 4 and fiber adapter 5, light splitting piece 4 is equipped with receiving terminal 2, the light-receiving of fiber adapter 5
Facing towards light splitting piece 4；Fiber adapter 5 is used for incoming fiber optic；Specifically, the transmitting terminal 1 and receiving terminal 2 are radium-shine diode mould
Group（TO-CAN）, in the present embodiment, transmitting terminal 1 is data transmission channel, and receiving terminal 2 is data receiving channel；The light splitting piece 4
Realize the transmission of the first wave length light sent out to transmitting terminal and the reflection to the second wave length from optical fiber.
The light that transmitting terminal 1 is sent out is projected from its light-emitting surface, and the direction of propagation of light and is being worn along the emergent shaft of transmitting terminal
Enter in the optical fiber in fiber adapter 5 after crossing light splitting piece 4；Light in fiber adapter after the reflection of light splitting piece 4,
It is incident in the light-receiving surface of receiving terminal 2, the light that receiving terminal receives enters optical axis along receiving terminal.
In this embodiment, be additionally provided with optoisolator 3, optoisolator 3 is set between transmitting terminal 1 and light splitting piece 4, the light every
From device 3 be a kind of allow Unidirectional light by Passive Optical Components, operation principle is the nonreciprocity based on Faraday rotation；
Its light that is used to prevent to project from fiber adapter 5 or reflect enters in transmitting terminal 1, to ensure the modulating performance of transmitting terminal 1
Well.
The optic path process of the present invention includes mainly two parts：
In the first portion, transmitting terminal 1 sends out the light of first wave length, and the light of the first wave length is by light splitting piece 4, and in light splitting piece
After being transmitted in 4, be incident upon in the fiber adapter 5, in the transmission process of first part entire path loss 10% with
It is interior；
In the second portion, the light of the second wave length in fiber adapter 5 projects, second wave length from the fiber adapter 5
Light reflected in light splitting piece 4 after, be incident in receiving terminal 2, the entire path loss in the transmission process of second part
Within 3%.
Therefore in the transmission process of the present invention, transmission loss is relatively low, advantageously ensures that its efficiency of transmission.
In this embodiment, transmitting terminal 1 is equipped with the non-spherical lens for having convergence effect to the light of injection, in favor of obtaining
Specific emergent shaft.
In this embodiment, receiving terminal 2 is equipped with lens, the focal length of focal length, that is, receiving terminal of lens, the first transmitting-receiving optics
The distance of the receiving terminal of secondary module to the light splitting piece is equal to the light splitting piece to the sum of the distance of the fiber adapter
The focal length of the receiving terminal of the first transmitting-receiving optical secondary module.
For better understanding of the present invention, its structural principle is described below, please refers to Fig. 5, is specially：
What the receiving terminal of transmitting-receiving optical secondary module entered optical axis and fiber adapter enters optical axis α at an acute angle.
Compared with the prior art, the optical axis direction that enters for entering optical axis direction fiber adapter of optical receiver tilts, and can reduce
The projecting height of optical receiver reduces the volume of transmitting-receiving optical device.
It is suitable to optical fiber with light splitting piece 4 if the distance of receiving terminal 2 to light splitting piece 4 is Β as shown in dotted portion in Fig. 5
The sum of distance A of orchestration 5 is equal to the focal length of lens F on receiving terminal 2.Light splitting piece 4 and fiber adapter 5 enter optical axis it is at 45 ° when,
The optical axis of receiving terminal 2 and fiber adapter 5 are in 90 °, and transmitting-receiving optical secondary module height is H, are equal to the height that Β adds receiving terminal 2
Degree.
As shown in bold portion in Fig. 5, when light splitting piece 4 and when entering optical axis angle reduction θ/2 of fiber adapter 5, receive
The optical axis at end 2 reduces θ with the optical axis angle that single mode optical fiber is inserted, and since focal length of lens F is constant, therefore receives and dispatches optical secondary module height H
In with the relevant sizes of Β be reduced to Β × cos θ=C, i.e., focal length it is constant in the case of receive and dispatch optical secondary module packaging height and reduce
Β ×（1-cosθ）.
It keeps focal length constant, light can be kept to enter the coupling efficiency in fiber adapter.
Enter the angle between optical axis by changing light splitting piece and fiber adapter, the height of receiving terminal can be reduced, be conducive to
The reduction of optical secondary module volume is received and dispatched, receiving terminal enters the angle that optical axis and fiber adapter enter between optical axis and also has occurred at this time
Change, α at an acute angle.
In this embodiment, when the angle between light splitting piece and transmitting terminal emergent shaft is at 45 °, best light splitting can be reached
Effect.
In the present invention, the angle [alpha] that optical axis and fiber adapter enter between optical axis that enters of receiving terminal is more than 78 ° and is less than
90 °, angle β is more than 0 ° and is less than 6 ° between the emergent shaft and fiber adapter of transmitting terminal enter optical axis.
Dotted line indicates before changing in Fig. 5, and solid line indicates after changing that before change, transmitting terminal emergent shaft enters with fiber adapter
Optical axis is in 0 degree of setting；
Angulation change between 5 optical axis of light splitting piece and fiber adapter θ/2, in order to maintain spectrophotometric result, the optical axis of transmitting terminal 1
Enter the angle beta between optical axis with fiber adapter and change correspondingly θ/2, but this angle change can influence optical coupling and be fitted into optical fiber
The efficiency of orchestration, in order to maintain coupling efficiency, it is preferable that the optical axis and fiber adapter of transmitting terminal 1 enter the angle between optical axis
θ/2 are between 3.5 ° to 4 °.So the emergent shaft of transmitting terminal 1 and fiber adapter enter the angle β between optical axis in this embodiment
Between 3.5 ° to 4 °.
In above structure, transmitting terminal 1 is tilted to 2 side of receiving terminal；Due to transmitting terminal 1 and the setting of receiving terminal 2 or tend to
On the same side, the overall volume of transmitting-receiving optical secondary module will be further reduced.
In the embodiment of the present invention, acute angle is the change deliberately carried out for improvement project, and not fabrication error etc. is non-master
Acute angle caused by sight factor.Prior art will theoretically realize the vertical angle that receiving terminal enters optical axis and fiber adapter enters optical axis
Degree, but is difficult to realize accurate vertical angle in reality, such situation is not the protection domain of the embodiment of the present invention, also with this hair
Bright embodiment has significant difference.
