This single mode fiber tail optical fiber novel structure, the structure is compact, is favorable to carrying out light path coupling integration with some special construction's waveguide chip.
Description
Technical field
The utility model relates to a kind of single-mode optical fiber pigtail.
Background technology
The grinding angle of existing single-mode optical fiber pigtail end face is generally 82 degree; When being coupled with major part " V " type PLC chip, angle is coupling; But can not with the angle automatching of " A " type PLC chip on the market; Be necessary design one can with the single-mode optical fiber pigtail of " A " cake core coupling matching.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of single-mode optical fiber pigtail, and this single-mode optical fiber pigtail novel structure, constructs compact, and can carry out coupling matching with " A " cake core
The technical solution of utility model is as follows:
A kind of single-mode optical fiber pigtail, comprise main body (1) and the bare fibre (4) of square column type, be provided with circular hole (2) in main body, an end of main body is provided with bellmouth (3), and bellmouth docks with circular hole; The dead in line of bellmouth and circular hole; The end of bare fibre is inserted in circular hole; Be provided with epoxide-resin glue (5) in bellmouth, the outer end of bellmouth is provided with UV glue (6);
The length of main body is 6.8-7.2mm;
The width of main body, with highly identical, is 2.45-2.55mm;
The overall diameter of bellmouth is 0.5 ~ 0.9mm;
The length of bellmouth is 1.0-1.4mm;
The interior diameter of bellmouth is identical with the diameter of circular hole, is 0.126 ~ 0.130mm;
The bottom Liang Tiao edge of main body is provided with square chamfering, and the bottom Liang Tiao edge of main body is provided with rounded corners.
As preferably, the length of main body is 7mm;
The width of main body, with highly identical, is 2.5mm;
The overall diameter of bellmouth is 0.7mm;
The length of bellmouth is 1.2mm;
The interior diameter of bellmouth is identical with the diameter of circular hole, is 128mm.
The distance of the axis of circular hole and the end face of main body is 1.5mm.
Epoxide-resin glue is 353ND epoxide-resin glue, and UV glue is 3106UV glue.
Beneficial effect:
Single-mode optical fiber pigtail of the present utility model, is designed with bellmouth, is convenient to penetrate optical fiber, and outer bore dia is 0.7mm, is conducive to being with the Φ 250um fiber section of coat to penetrate in bellmouth, bonds with 353ND glue, ensures that optical fiber not easily pulls out from bellmouth; In addition, the bottom Liang Tiao edge of main body is provided with square chamfering, and this square chamfering can well to kapillary positioning and locking when grinding, and grinding efficiency is high, and quality is good.
