How to weld two fiber optics:
In this book we will show you how to weld two fiber optics. For that, we're going to use a fiber
from a pigtail and weld it again. But before that, we need to see what materials we need.
Materials:
1. Pigtail with the fiber optic.
2. Plier to help remove the cover from the cable
3. Alcohol to clean the fiber optic
4. High precision cut fiber cleaver to do a precise cut of the fiber
5. Fiber splicer used to weld and put the protection on the fiber
6. Heat-shrink to protect the fiber.
7. Optical power meter to test the fiber.
Step 1: Cutting and striping the fiber optic
For the first step we need to cut the pigtail in the middle and then remove the exterior
cover of the cable and the cover of the fiber optic.
Step 2: Cleaning and precision cutting
After getting the fiber out, we need to give it a good clean so we can do the precision
cutting. After this, repeat steps 1 and 2 with the other half of the pigtail.
Step 3: Welding
Now we can weld the two fibers to each other using the fiber splicer. We put the fibers in
the machine aligned. Not all the fiber splicers can make an automatic aligning of the fibers,
but this one can. After that, just press the button and the device does the welding.
Step 4: Protection with heat-shrink
Once the welding is done, we need to protect the fiber from breaking and getting dirty
with the heat-shrink. We put the fiber optic inside the heat-shrink and then put it in the heater of
the machine.
Step 5: Testing
Finally after welding and protecting the fiber optic, we need to test it with the optical
power meter. The test of the fiber optic cables allows to identify points of light losses.
