Ceramic insertion core APC faces in connector are in isolator magnet ring centre position into 90 degree of angles, optoisolator polarizer.It is main
Defect is：1st, the light that old attachment process has reflection can reach separator surface and cause to reflect again and enters optical fiber biography
Defeated system forms interference signal, causes poor signal quality；2nd, isolator polarizer is mounted on centre position, and existing makes input path
Phenomenon outside the coverage of isolator polarizer.
The content of the invention
The purpose of this utility model is that in view of the above-mentioned defects in the prior art, there is provided a kind of anti-interference attachment knot of isolator
Structure, the light of new design reflection will not arrive isolator wave plate surface, will not again reflect and enter fibre-optic transmission system (FOTS)
Interference signal is formed, so as to avoid signal interference, improves signal quality；New isolator polarizer attachment, can make into
Light path is penetrated completely in the coverage of isolator polarizer, makes light antijamming capability stronger.
In order to realize above-mentioned technical proposal, the technical solution of the utility model is：
A kind of anti-interference mounting structure of isolator, including housing, fiber connector, optoisolator, ceramic insertion core, the light
Fine connector, ceramic insertion core, optoisolator are from left to right sequentially arranged in housing, and the fiber connector is sheathed on ceramics and inserts
The periphery of core and the one end for being connected to housing, the optoisolator are installed in the other end inner cavity of housing；The optoisolator
Coaxial with ceramic insertion core, optoisolator polarization inclined-plane is consistent with the ceramic insertion core APC faces direction in fiber connector.
As the improvement to above-mentioned technical proposal, the optoisolator polarizer abuts incident side low dot location.
Compared with prior art, the utility model has the advantages and positive effects of：
The anti-interference mounting structure of isolator of the utility model, optoisolator polarization inclined-plane and the ceramics in fiber connector
Lock pin APC faces direction is consistent；Optoisolator polarizer abuts incident side low dot location.The light that advantage is 1, new design reflects is not
Isolator wave plate surface can be arrived, will not again reflect and enter fibre-optic transmission system (FOTS) formation interference signal, so as to avoid
Signal interference, improves signal quality；2nd, new isolator polarizer attachment, can make input path completely inclined in isolator
Shake the coverage of piece, make light antijamming capability stronger.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is attached drawing needed in technology description to be briefly described, it should be apparent that, drawings in the following description are only this

Within protection domain.
As illustrated in fig. 1 and 2, the anti-interference mounting structure of the isolator of the utility model, including housing 1, fiber connector 2,
Optoisolator 3, ceramic insertion core 4, the fiber connector 2, ceramic insertion core 4, optoisolator 3 are from left to right sequentially arranged at housing
In 1, the fiber connector 2 is sheathed on the periphery of ceramic insertion core 4 and is connected to one end of housing 1, and the optoisolator 3 is installed
In the other end inner cavity of housing 1；The optoisolator 3 and ceramic insertion core 2 are coaxial, and optoisolator polarization inclined-plane is connected with optical fiber
6 directions of ceramic insertion core APC faces in first 2 are consistent.
The optoisolator polarizer abuts incident side low dot location.
The anti-interference mounting structure of isolator of the utility model, optoisolator polarization inclined-plane and the ceramics in fiber connector
6 directions of lock pin APC faces are consistent；Optoisolator polarizer abuts incident side low dot location.Advantage is 1, new design, laser 5
Emergent light outgoing, light reflects through optoisolator 3, and the light of reflection will not arrive isolator wave plate surface, will not secondary reflection again
Back into ceramic insertion core light hole 7, interference signal is formed to fibre-optic transmission system (FOTS), so as to avoid signal interference, is changed
It has been apt to signal quality；2nd, new isolator polarizer attachment, can make covering model of the input path completely in isolator polarizer
Enclose, make light antijamming capability stronger.
