Fixed optical fiber.Fiber stub is applied in the products such as the light jumper in optical communication field, optical connector, optical module.Such as Fig. 1.
Status fiber stub is classified according to concentricity and is used, and a pair of ceramic insertion core docks in ceramic sleeve when use.Together
Heart degree is lesser, and the loss for docking generation is smaller, and concentricity is biggish, generates biggish performance loss.Existing standard regulation, it is single
Concentricity≤1.4um of mould lock pin, to realize in practice insertion loss be less than 0.1DB or 0.2DB when, can only with same concentricity≤
0.5um or concentricity≤1.0um lock pin make.Such as Fig. 2.
Now when making the optical patchcord of high request, when as more demanding such as interchangeability, except selecting, concentricity is smaller to be inserted
Outside the scheme of core, lock pin eccentric position is adjusted using eccentric tester in wire jumper manufacturing process, connector head is rotated,
It allows a pair of of lock pin of docking to be adjusted in same quadrant, can be reduced corresponding butting error.Such as Fig. 3.
Status fiber stub is classified according to concentricity and is used, and the center in the lock pin hole at both ends is docked at random when docking,
The center in hole can generate docking in different quadrants, when center is not in same quadrant, generate biggish butting error.Such as figure
2。
The mode adjusted in optical patchcord manufacturing process with eccentric tester, in the case where also only having limited optical fiber affixed, and
And can only generally adjust 4~6 position because the structure of plug core tail handle has limited rotation and orientation.This adjusting improves
Partial properties, for causing to scrap and can not improve completely since lock pin concentricity being bad or adjusts discomfort, entire connector head
It scraps, also increases loss from spoilage.

The technical solution of the utility model is as follows:
The middle part of a kind of fiber stub, including casing, the first lock pin and the second lock pin, first lock pin is equipped with the first light
Fine duct, the middle part of second lock pin are equipped with the second optical fiber duct, and described sleeve pipe is for fixing first lock pin and second
Lock pin, the size of its eccentric direction and the degree of eccentricity is marked on first lock pin, the second lock pin respectively, and use process makes caudal peduncle
With eccentric position at fixed orientation, and the orientation is clearly marked, the degree of eccentricity size of first lock pin, the second lock pin
Properly, first lock pin and the second lock pin are inserted into described sleeve pipe from one end of described sleeve pipe respectively according to the orientation in opposite directions
Interior, the orientation for marking first lock pin and the second lock pin is corresponding, first optical fiber duct and the second optic fibre hole
Road docking.
Further, in the above-mentioned technical solutions, the degree of eccentricity of first lock pin and the second lock pin in reasonable selection or
Pairing is in use, lock pin concentricity also can reach lower insertion loss when being greater than former classification standard.
Further, in the above-mentioned technical solutions, the hole center in first optical fiber duct and the second optical fiber duct is docked
Direction dislocation may be implemented within the scope of less than one quadrant, realize less than the docking dislocation within the scope of 30 degree.
Further, in the above-mentioned technical solutions, first lock pin, the second lock pin and casing can be by ceramics, stainless steel
Or glass material is made.
Further, in the above-mentioned technical solutions, first lock pin and the second lock pin are band handle lock pin, lock pin of usheing to seat,
Or wire jumper, device containing this feature lock pin.
Compared with prior art, the utility model has the beneficial effects that: the structure of the utility model designs, it may make one
The eccentric position of lock pin docking both sides in assembly is docked in corresponding same orientation, makes two lock pin centre bores of docking in this way
The docking of centre bore is realized in the docking of same quadrant or even smaller section, to promote docking performance.For there is interchangeability to want
For the optical patchcord asked, using the utility model, it will not have to adjust using Eccentric Instrument in process of production, be wanted using concentricity
When seeking the lock pin slightly larger than former classification standard, installation capability is also fully consistent with requirement, not only reduces assembly cost, and reduce
Loss from spoilage.
