This novel glass optic fibre capillary novel structure, the structure is compact, and its tip has nested bell mouth, is convenient for cooperate with phi's 0.9 tight coated fibers, is applied to the coupling of the inside emergent light of DFB laser instrument and draws forth.
Description
Technical field
The utility model relates to a kind of novel glass optical fiber capillaries.
Background technology
The optical fiber capillaries of existing Φ 1.8 is all cylindrical, occasionally to have D type, but taper hole is just applicable to the small taper hole of 250um bare fibre; Be not applicable to the large taper hole D type kapillary of Φ 0.9 hard-pressed bale fibre, so the optically-coupled not being suitable for Distributed Feedback Laser inside is drawn; Therefore, be necessary to design a kind of novel glass optical fiber kapillary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel glass optical fiber capillaries, this novel glass optical fiber capillaries novel structure, construct compact, its end has nested bellmouth, be convenient to coordinate with the tightly packaged fiber of Φ 0.9 make single fiber tail optical fiber, draw for the radiative coupling of laser instrument.
The technical solution of utility model is as follows:
A kind of novel glass optical fiber capillaries, comprise main body (1), be provided with circular hole (2) in main body, an end of main body is provided with male-tapered hole (3) and internal tapered hole (4); Male-tapered hole, internal tapered hole are docked successively with circular hole; The dead in line of male-tapered hole, internal tapered hole and circular hole and main body;
The xsect of main body is D font, and D font xsect refers to that disc goes one piece of remaining part along flat-sawn.
The length of main body is 6.3 ~ 6.7mm;
The diameter of main body is 1.79 ~ 1.81mm;
The overall diameter in male-tapered hole is 1 ~ 1.1mm; The interior diameter in male-tapered hole is 0.7-0.9mm;
The length in male-tapered hole is 0.9 ~ 1.1mm; The total length (degree of depth) of male-tapered hole and internal tapered hole is 1.8 ~ 2.1mm;
The interior diameter of bellmouth is identical with the diameter of circular hole, is 1.126 ~ 0.128mm.
As preferably: the length of main body is 6.5mm;
The diameter of main body is 1.8mm;
The overall diameter in male-tapered hole is 1mm; The interior diameter in male-tapered hole is 0.9mm;
The length in male-tapered hole is 1mm; The total length (degree of depth) of male-tapered hole and internal tapered hole is 2mm;
The interior diameter of bellmouth is identical with the diameter of circular hole, is 0.127mm.
H=0.2*D, D are the overall diameter of main body, and h is the distance of string to the center of circle, H=D-h.
Beneficial effect:
Novel glass optical fiber capillaries of the present utility model, end has nested bellmouth (to be docked with internal tapered hole by male-tapered hole and form), be convenient to coordinate with the tightly packaged fiber of Φ 0.9, and the xsect of main body is D font, for the laser instrument butt coupling with D font port with outside, its profile can meet the technical requirement of Distributed Feedback Laser encapsulation coupling in other words.
