Abstract
The utility model discloses a ceramic ferrule for an optic fiber connector. The ceramic ferrule for an optic fiber connector comprises a ferrule body with an inclined-planed end face. The end face of the ferrule body and the plane vertical to the center shaft of the ferrule body are at an included angle of 9 DEG. When the ceramic ferrule for the optic fiber connector is matched with a ceramic sleeve, the pulling and inserting force consistency, the twisting stability and the interchangeability are more perfect. Furthermore the reliability of the optic fiber connector is improved. In addition, when the ceramic ferrule is matched with a laser to be used, the return loss can be increased, the interference to a laser chip is reduced, and the laser can work more stably. The ceramic ferrule for the optic fiber connector is applicable for all kinds of SC/APC type optical fiber connectors.
Description
Technical field
The utility model belongs to optical fiber transmission technique field, relates to a kind of fiber active linker ceramic insertion core.
Background technology
Fiber active linker is the centering link in joint, and the split coupling by fiber active linker inside between optical fiber connects, and guarantees the highest switching performance between optical patchcord.Fiber active linker comprises housing, ceramic sleeve, ceramic insertion core etc., and fiber active linker can be divided into FC, PC and APC type according to ferrule endface shape.
The fiber active linker of APC type of the prior art, the end face of its ceramic insertion core is inclined-plane, the angle between the vertical plane of the central shaft of end face and lock pin is 6 ° or 8 °, when such ceramic insertion core and chip laser device are used in conjunction with, there will be following point:
1. some index of laser instrument is as centre wavelength, spectrum width, shake etc., can variation, affect laser instrument normally to work;
2. laser instrument return loss index variation, the light that laser instrument sends is after ferrule endface reflection, and the light of return laser light device inside increases, and affects the serviceable life of laser instrument.
Utility model content
For solving the above deficiency existing in prior art, it is a kind of fiber active linker ceramic insertion core of 9 ° that the utility model provides end slope angle, when it coordinates with ceramic sleeve, pulling-inserting force consistance, twists stability and exchange performance is more excellent.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of fiber active linker ceramic insertion core, comprises that end face is the lock pin body on inclined-plane, and the angle between the vertical plane of the central shaft of the end face of described lock pin body and lock pin body is 9 °.
Owing to having adopted technique scheme, compared with prior art, obtained technical progress is the utility model:
Angle between the vertical plane of the end face of a kind of fiber active linker ceramic insertion core of the present utility model and the central shaft of lock pin is made as 9 °, in the time that ceramic insertion core coordinates with ceramic sleeve, can improve pulling-inserting force consistance, twisting stability and the interchangeability of ceramic insertion core, and then improve the reliability of fiber active linker; In addition, when this ceramic insertion core and laser instrument are used in conjunction with, can increase the return loss of fiber active linker, and reduce the interference to chip of laser, make more steady operation of laser instrument.
A kind of fiber active linker ceramic insertion core of the present utility model is applicable to SC/APC type fiber active linker.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is done further to describe in detail.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic diagram that the lock pin body 1 in Fig. 1 coordinates with ceramic sleeve 2.
In figure: 1, lock pin body; 11, end face; 2, ceramic sleeve; Angle between the vertical plane of the central shaft of α, end face and lock pin body 1.
Embodiment
embodiment
The present embodiment is a kind of fiber active linker ceramic insertion core, and structure as shown in Figure 1, comprises lock pin body 1.
This end face of end face 11(of lock pin body 1 is the end face coordinating with joints of optical fibre plug-in mounting) be inclined-plane.
The above architectural feature of the present embodiment, same as the prior art, the difference of itself and existing product is:
Angle α between the vertical plane of the central shaft of end face 11 and lock pin body 1 is 9 °.
The present embodiment is applicable to various SC/APC type fiber active linkers, and lock pin body 1 and ceramic sleeve 2 fit systems are as shown in Figure 2.The experiment proved that, they can improve pulling-inserting force consistance, twisting stability and the interchangeability of lock pin body 1 after coordinating, and then improve the reliability of fiber active linker.
The present embodiment is applied to after fiber active linker, can increase return loss; When corresponding fiber active linker and laser instrument are used in conjunction with, can reduce the interference to chip of laser, make the work of laser instrument more stable.
