Abstract
The invention relates to an optical fiber of a light splitting path and a production method thereof and belongs to the field of optical fiber communication. The optical fiber of the light splitting path is structurally characterized by being composed of an optical fiber body and an optical lens, wherein the optical lens is arranged at one end of the optical fiber body. In the production method, a discharger is used for heating so that the optical fiber is broken; and at the time of welding the optical fibers, if two optical fibers are not successfully welded and are separated after the optical fibers discharge, the end faces of the optical fibers are tapered or spherical. The product prepared by the production method has the advantages of good light directionality, less light reflection, convenience for processing, high yield and good stability.
Description
Technical field
The present invention relates to a kind of minute light path optical fiber and manufacturing approach thereof, belong to optical-fibre communications field.
Background technology
Along with improving constantly of optical fiber telecommunications system capacity and speed, the optical device especially importance of the directivity (DL) of fiber optic passive device (Passive device) more and more causes the attention of user and manufacturer.
To the 1XN shunt, what directivity was described is to advance light through the influence degree of device to adjacent output terminal from certain output terminal.All there be N-1 unnecessary unsettled end face in its inside of arbitrary 1XN shunt.The reflection of these vacant end faces has greatly influenced the directivity index of device, must eliminate the reflection of these vacant end faces.The anti-processing or anti-the processing inadequately that disappear if vacant end face is not done to disappear is easy to cause the directivity index of device to be lower than desired level greater than 55dB on the engineering.The way of many manufacturers is that the branch light path optical fiber of shunt is connected with the optical fiber of return loss test set or power meter, seeing the reading of instrument, and meanwhile optical fiber cut off with instrument, until index reaches till the requirement.No matter how many angles of fiber end face is actually, as long as index is qualified.Unique what be careful is if angle is too big, and easy fragmentation of fiber end face or glass chip drop to optical fiber surface and make the index variation when carrying out the termination protection.The benefit of this method be can the Real Time Observation directivity size, yield rate is high.Shortcoming is to have increased labour cost and instrument depreciation cost, and success ratio is not high.
Summary of the invention
Technical matters to be solved by this invention provides that a kind of reasonable in design, direction of light property are good, reflection less, easy to process, yield rate is high, the branch light path optical fiber of good stability.
Another technical matters to be solved by this invention provides the branch light path optical fiber manufacturing method that a kind of technological design is reasonable, technology simple, the yield rate success ratio is high, working (machining) efficiency is high, labour cost is low, the instrument wearing and tearing are few.
It is this minute light path optical fiber that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and its design feature is: be made up of fiber body and lens, described lens are arranged on an end of fiber body.Thereby light reflection can be effectively avoided in the design of lens, improves directivity, and the lens processed of this kind method, can adapt to all-environment variation, thus the reliability and the serviceable life of assurance Network Transmission.
As preferably, lens of the present invention are for disperseing away light wave, avoid the lens of light reflection, raising directivity.
As preferably, lens of the present invention are the Fresnel convex lens.Guarantee directivity and reliability, thereby guaranteed product quality.
It still is a kind of minute light path optical fiber manufacturing method that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and its manufacturing step is:
A, good unwanted that root input end fiber of shunt is put into the discharger fiber clamp drawing awl;
Adopt the discharger welding optic fibre, use for a long time big electric current
B, open discharge switch, when arc discharge, the optical fiber part is heated fusion and makes optical fiber fusing;
C, continuation are heated with arc discharge, time 3000ms, and the internal layer temperature reaches 5000-8000 ℃, and when exospheric temperature was 2000-3000 ℃, optical fiber was in outer scorification, and its end face is shrunk to the lens of spheroidal automatically because of surface tension effects;
D, natural cooling optical fiber are accomplished the manufacturing that divides light path optical fiber.
As preferably, among the step b of the present invention, the parameter of arc discharge is: 13.5B/4.5V positive electricity and negative electricity.
The present invention compares with prior art and has the following advantages and effect: through the method for arc discharge fiber end face is processed sphere lens with discharger, can guarantee the index on optical fiber connector surface.The yield rate success ratio is high, working (machining) efficiency is high, labour cost is low, the instrument wearing and tearing are few.Its end is just as a miniature bulb; Be equivalent to a sphere lens; Just so-called Fresnel convex lens; Scioptics disperse away light wave; Thereby effectively avoid light reflection, improve directivity, and the lens processed of this kind method; All-environment variation be can adapt to, thereby the reliability and the serviceable life of Network Transmission guaranteed.
