For fiber fusion splicer, "do things the right way, do the right thing."
Tumtec science lesson - correct use of fiber fusion machine.
In our life, a variety of products emerge one after another, but few of them is long service life. If a product wants to live a long life, not only the quality of the product itself, but also the correct use is very important.For communication engineers, more contact products should be the fusion splicer, optical fiber fusion splicer is high-tech mechanical products, comprehensive properties of this products is relatively high, so how is the correct use of optical fiber splicing steps?Let's take a look at the Tumtec fusion splicer!
The first step is to prepare the optical fiber
Before fiber splicing, fiber preparation requires three steps:
1. coating stripping
At least 50mm of coating is left after stripping the sheath (loose sleeve fiber is the same as tight sleeve fiber).Remove the coating layer with stripper, the length is 30~40mm.
2. clean the fiber with a cotton paper dipped in alcohol.
3. fiber cutting
Use highly sophisticated cutting tools to cut the fiber.In order to ensure the quality of splicing, high precision cutting cleavers, such as T9 series optical fiber cleavers, should be used for cutting, and the length of optical fiber cutting should be strictly controlled (as shown in the figure on the right).
Note: remember to wear heat-shrinkable sleeve when fiber pretreatment
Make sure the bare optical fiber and its cutting surface are not dirty.
- avoid shaking the optical fiber in the air
- check whether the v-shaped groove and pressure hammer are clean. If not, clean it with a cotton swab dipped in alcohol
Conduct automatic fiber inspection
After the fiber is loaded into the fusion splicer, start the machine. Before splicing, it will automatically do discharge cleaning. After discharging cleaning, check the cutting Angle of each fiber and the quality of cutting end face.If the measured cutting Angle of the optical fiber is greater than the set limit value, or the end face of the optical fiber is found to have burrs, the buzzer will alarm, and the display will pop up a prompt box to remind the operator.
Start splicing operation steps
(1) open the splicer electromechanical source, when only splicing labeled SM fiber (itu-t-g. 652), recommended [SM Mode] Mode;
(2) confirm splicing and heating modes. When splicing different types of optical fibers, recommend [Auto Mode] Mode, but the splicing speed will be a little slower;
Clean fiber coating or tight sleeve
Insert the fiber into the heat-shrinkable protective sleeve；
Peel the fiber and clean the fiber
Pure alcohol with a concentration of more than 99%
Make sure that the coated residue or other dirt has been removed from the stripped fiber
(4) put the fiber into the fixture
place the electrode between the edge of the v-groove and the central position of the bipolar electrode rod connection
Note: do not slide the fiber along the v-groove. The cutting surface of the fiber should be beyond the v-groove position, but not beyond the tip of the electrode rod
Place the electrode on the edge of the v-shaped groove and
The two poles are connected between the central positions of the electrodes
6. Cover the windproof cover to start automatic welding
The LCD screen can be viewed during splicing
7 .Remove the fused fiber
Move the heat-shrinkable tube in the middle of the heating furnace
The optical fiber keeps the fusion contact at the center of the heat-shrinkable sleeve
Cover the heater and start heating
Note: in case of large splicing loss or large change in the altitude of the environment, [stable electrode] and [discharge correction] must be performed before splicing. If you need more information about this, pls see the previous contents which release by Tumtec!
