The preparation method of the optical-fiber coupling connector of pluggable connection described in the present embodiment, comprising the following steps:
(a) fused biconical taper: by two or multifiber respectively in shell about 18mm, be placed in high-temperature field by the way of parallel
Heating melting is simultaneously stretched to both ends, and the fiber section after shelling in high-temperature region softens and by two side stretchings, deformation occurs, shape
At the small bicone in the big centre in both ends;The fibre core of two in conical region or multifiber is since distance is very close to leading to it
Evanescent field in the energy that overlaps exchange, the parameters such as elongation degree are melted by control, different coupling optical fiber is made;
(b) preparation of optical fiber head: controlling tensile elongation by changing rate of extension and hydrogen-oxygen flow, will melt the cone after drawing
Section length control is 17~18mm, then will melt the cone area for coupling optical fiber after drawing in step (a) using accurate cutting and cuts
At two independent first cone area's optical fiber heads 111 and second cone area's optical fiber head 211;
(c) encapsulation grinding: first after cutting is bored into area's optical fiber head 111 and second cone area's optical fiber head 211 respectively penetrates length
The 22 midpoint adhesive curing of the first contact pin 12 and the second contact pin of caudal peduncle, finally grinds, and encapsulates the first tail optical fiber 112 using integrated optical cable
With the second tail optical fiber 212;
(d) connection of optical-fiber coupling connector:
1. calibration: after light source power is stablized, being proofreaded to power meter, make its loss when being connected directly with light source
For 0dB, due at least needing to survey two channels, so also needing to carry out identical calibration to another power meter;
2. will be securely fixed after the first contact pin 12 and the docking of the second contact pin 22 respectively with stationary fixture first, if fixed
Sliding may occur for pine or even fall to cause its end face impaired in the aligning process, influence to continue to use, while can also reduce
Production efficiency;Secondly corresponding first contact pin caudal peduncle 121 is clamped using adjustable clamp and coupling is adjusted in the second contact pin caudal peduncle 221
It closes;
3. light passing: by input optical fibre head and light source, output optical fibre head is connected with power meter by optical fiber, optical fiber and optical fiber
Connection can be realized its welding with the machine of welding;The input optical fibre head is the first contact pin 12 or the second contact pin 22;
4. coupling: the first contact pin 12 slowly being moved to away from first 13 position 1~2mm of right end of core, the second contact pin 22 is adjusted
And slowly move it in second core 23, sextuple bracket is constantly regulate, registration in light power meter is observed, when the numerical value of display accords with
When closing our requirement;The fore-and-aft distance for then adjusting the second contact pin 22, connects in the second contact pin 22 with the first contact pin 12
When touching, sextuple bracket is adjusted, the second contact pin 22 is made to draw back 2~3mm;
5. putting adhesive curing: when regulating the first contact pin 12 and the second 22 relative position of contact pin, in the first contact pin 12 and
One core 13 in the gap between second contact pin 22 and second core 23, is first clicked and entered a small amount of uv-curable glue and is pre-fixed,
Then with ultraviolet light to being irradiated simultaneously at two dispensings, glue will slowly solidify, and when solidifying, numerical value has subtle wave
It leads, adjusting bracket can be finely tuned and be allowed to numerical stability;Then continue to insert uv-curable glue within the cleft, carry out secondary curing,
Improve the reliability of product;
6. baking: and then under the conditions of 85 DEG C, 5h is placed, improve solidification effect;Other elements are assembled again, obtain product;
7. product test.
