Abstract
The utility model discloses an interface assembly of an optical transceiver module. The interface assembly comprises a housing, a PIN diode mounted on one side of the housing, a plugging core mounted on the top of the housing, a laser which corresponds to the plugging core and which mounted on the bottom of the housing, and a light splitting sheet facing the laser and the plugging core in an inclined manner. The housing is equipped with a hollow cavity into which the PIN diode, the plugging core, and the laser are all inserted. The light splitting sheet is also arranged in the hollow cavity. The housing is equipped with an inner surface facing the PIN diode. A black glue salient point with an arc surface is disposed on the inner surface facing the PIN diode. The black glue salient point with an arc surface protrudes towards the PIN diode and absorbs light reflected by the light splitting sheet so as to reduce optical crosstalk.
Description
Technical field
The utility model relates to field of photoelectric devices, especially a kind of optical transceiver module interface module.
Background technology
See also Figure 1 and Figure 2, be existing optical transceiver module interface module (BOSA), it comprises shell 20 ', is installed on the laser instrument 50 ' that the PIN type diode 30 ' of shell 20 ' one side, the lock pin 40 ' that is installed on shell upper and corresponding lock pin are installed on shell 20 ' bottom, and the dip plane is to the light splitting piece 60 ' of PIN type diode 30 ' and lock pin 40 '.Described shell 20 ' has cavity 21 ', and PIN type diode 30 ', lock pin 40 ', laser instrument 50 ' are all charged in this cavity 21 '.Light splitting piece 60 ' is arranged in cavity 21 ' equally.
And this optical transceiver module interface module ubiquity optical crosstalk problem.Reason is:
Out light has 1/2 light to enter in the lock pin 40 ' by light splitting piece 60 ' in the laser instrument 50 '; 1/2 light reflexes to inner surface of outer cover 22 ' in addition; Reflex to light splitting piece 60 ' by inner surface of outer cover 22 ' along horizontal direction again; There is 1/4 light transmission to go to enter in the PIN type diode 30 ', forms Crosstalk.And enter the light of lock pin 40 ', and there is part to be returned on the light splitting piece 60 ' by lock pin 40 ' end face reflection, wherein 1/2 can be reflected in the PIN type diode 30 ', form optical crosstalk.By lock pin 40 ' light out, there is 1/2 light to enter in the PIN type diode 30 ' by light splitting piece 60 ', part can be returned light splitting piece 60 ' by PIN type diode 30 ' reflected in parallel, 1/2 light transmission in the part goes by inner surface of outer cover the 22 ' parallel light splitting piece that returns, see through go formed again Crosstalk.
Therefore, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of optical transceiver module interface module that reduces Crosstalk is provided.
For achieving the above object, the utility model optical transceiver module interface module can adopt following technical scheme:
A kind of optical transceiver module interface module comprises shell, is installed on the laser instrument that the PIN type diode of shell one side, the lock pin that is installed on shell upper and corresponding lock pin are installed on outer casing underpart, and the dip plane is to the light splitting piece of laser instrument and lock pin; Described shell has cavity, and PIN type diode, lock pin, laser instrument are all charged in this cavity; Light splitting piece is arranged in cavity equally, and described shell is provided with the inside surface in the face of PIN type diode, and described inside surface in the face of PIN type diode is provided with to the black glue salient point of the outstanding arc surface of PIN type diode direction.
Compare with background technology, the utility model optical transceiver module interface module absorbs light that light splitting piece reflects to reduce optical crosstalk by the black glue salient point of arc surface is set.

Fig. 2 is the inner structure schematic diagram of optical transceiver module interface module in the prior art.
Fig. 3 is the inner structure schematic diagram of the utility model optical transceiver module interface module.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also shown in Figure 3, the utility model discloses a kind of optical transceiver module interface module, comprise shell 20, be installed on laser instrument 50(" top " here that the PIN type diode 30 of shell 20 1 sides, the lock pin 40 that is installed on shell 20 tops and corresponding lock pin 40 be installed on shell 20 bottoms and reach " bottom " for corresponding PIN type diode 30 location expressions), and the dip plane is to the light splitting piece 60 of laser instrument 50 and lock pin 40.Described shell 20 has cavity 21, and PIN type diode 30, lock pin 40, laser instrument 50 are all charged in this cavity 21; Light splitting piece 60 is arranged in cavity 21 equally.Described shell 20 is provided with the inside surface 22 in the face of PIN type diode 30.Described inside surface 22 in the face of PIN type diode 30 is provided with to the black glue salient point 23 of the outstanding arc surface of PIN type diode 30 directions.
The utility model optical transceiver module interface module can effectively reduce optical crosstalk, and reason is:
50 li light out of laser instrument have 1/2 light to enter in the lock pin 40 by light splitting piece 60,1/2 light reflexes to the black glue salient point 23 of arc surface in addition, this part reflexes to light on the black glue salient point 23 of arc surface and partly is absorbed part and is reflected away, can not enter PIN type diode 30 along horizontal direction again and form Crosstalks.There is 1/2 light to enter PIN type diode 30 by lock pin 40 light out by light splitting piece 60, part can be returned light splitting piece 60 by PIN type diode 30 reflected in parallel, wherein 1/2 light transmission goes to the black glue salient point 23 of arc surface, is not partly reflected away and can enter PIN type diode 30 formation Crosstalks along horizontal direction again by the black glue salient point 23 of arc surface equally.
