Abstract
The invention discloses an interface assembly of an optical transceiver module. The interface assembly comprises a laser device, an isolator, a spectroscopic plate fixing seat, a 45-degree spectroscopic plate, a ceramic ferrule, a zero-degree spectroscopic plate and a detector. The laser device, the isolator, the spectroscopic plate fixing seat, the 45-degree spectroscopic plate and the ceramic ferrule are sequentially placed on the same horizontal light path, and the zero-degree spectroscopic plate and the detector are sequentially placed on a vertical light path of the 45-degree spectroscopic plate. The isolator is mounted on the spectroscopic plate fixing seat, so that loss of light which emitted by the laser device after the light passes through the isolator with small clear aperture is low. The interface assembly of the optical transceiver module is low in cost, and an operation process of the interface assembly is convenient.
Description
Technical field
The present invention relates to technical field of optical fiber communication, particularly a kind of optical transceiver module interface module.
Background technology
Use the optical transceiver module interface module (BOSA) of isolator in the prior art; Isolator is contained on the laser instrument pipe cap; Because isolator and laser instrument close proximity, the isolator clear aperature needs bigger, and the loss of the light transmission isolator of laser instrument emission just can meet the demands; And the big isolator cost of clear aperature influences cost of products than higher.In addition, the secured in alignment of traditional structure isolator and laser instrument is difficulty, and the loss of the light transmission isolator of laser instrument emission is bigger.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of interface module of optical transceiver module cheaply.
For realizing above-mentioned purpose, optical transceiver module interface module of the present invention can adopt following technical scheme:
A kind of optical transceiver module interface module is included in laser instrument, isolator, light splitting piece holder, 45 degree light splitting piece and the ceramic insertion cores placed successively on the same horizontal optical path; And be included on the vertical optical path of 45 degree light splitting pieces and place 0 degree light splitting piece, detector successively.
The present invention is compared with prior art: the present invention is through being contained in isolator on the light splitting piece holder, makes that the loss of the light transmission isolator of laser instrument emission is still very little when adopting the little isolator of clear aperature, and cost of products is lower, and operating procedure is more convenient.
Description of drawings
Fig. 1 is the structural representation of optical transceiver module interface module of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment; Further illustrate the present invention; Should understand following embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Please combine shown in Figure 1ly, the present invention discloses a kind of optical transceiver module interface module, is included in laser instrument 1, isolator 2, light splitting piece holder 3,45 degree light splitting piece 4 and the ceramic insertion cores 5 placed successively on the same horizontal optical path; And be included on the vertical optical path of 45 degree light splitting pieces 5 and place 0 degree light splitting piece 6, detector 7 successively.Isolator 2 is contained on the light splitting piece holder 3, and in abutting connection with 45 degree light splitting pieces 4.45 degree light splitting pieces 4 and 0 degree light splitting piece 6 also are fixed on the light splitting piece holder 3.
Please combine shown in Figure 1ly again, described ceramic insertion core 5 is as far as possible near 45 degree light splitting pieces 4.The light of laser instrument 1 emission is through isolator 2; Again through being coupled in the optical fiber of ceramic insertion core 5 behind the 45 degree light splitting pieces 4; The light of laser instrument 1 emission hot spot when the front end face 101 of laser instrument 1 is maximum, and the hot spot when the front end face 103 of ceramic insertion core 4 is minimum, and isolator 2 is on the light splitting piece holder in this structure; Near ceramic insertion core 5 one ends, the hot spot at front end face 102 places of isolator 2 is little more a lot of than the hot spot at laser instrument 1 front end face 101 places at this moment as far as possible.The light of laser instrument 1 emission is very little through less low-cost isolator (as: clear aperature is the isolator of Φ 0.6mm) the back loss of clear aperature, can be coupled in the optical fiber in the ceramic insertion core 4.And the light of ceramic insertion core 5 emissions through turning 90 degrees behind the 45 degree light splitting pieces 4, again through behind the 0 degree light splitting piece 6, is received by detector 7.According to above light path principle, this structure can realize a kind of low cost optical transceiver module interface module.
And isolator 2 is fixed on operating procedure on the light splitting piece holder 3 than being fixed on more convenient to operate on the laser instrument.
