How to Fusion Splice Fiber Optic Cable

Fiber optic splicing products are used to make a perfect melting of the bare optical fiber together. It refer to the combining of two lengths of cables to create one longer cable. You may need to splice fiber optic cables for reasons like combining shorter cables, replacing broken cables or connecting intermediate points between a transmitter and receiver. Fusion splicing and mechanical splicing are two methods for splicing fiber together. Fusion splicing is the most usually used method to splicing large fiber counts and for permanent fiber connections. Here we will discuss the steps for fusion splice fiber optic cables.
1. Fiber Preparation
Prepare the fiber by taking off the outside sheath of the fiber optic cable, cutting the aramid strength member, and then stripping away the buffer layer from the fiber with fiber stripper.
In this step, you nee to make sure a clean environment for the bare fiber, no filling gel or finger touching are allowed to affect the refraction index of the cable.
2. Fiber Cleaving
After prepared the fibers, you need to make the end of the fibers cut squarely by cleaving the fibers. A good quality fiber cleaver is essential in this step, which will release less light loss and reflection problems by producing a fibre end that is clean and flat with no hackle. Place the prepared fiber into the groove on the fiber optic cleaver, clamp the cables in place, close the lid and then press the cleaving lever to complete the cleaving process.
3. Fusing Splicing
Put the fibers into the place in the fusion splicer, bring the end of fibers close together and pressing start on the fusing splicing machine. You will be reminded the process is complete.
4. Splice Protection
Once the splice has been completed, take the spliced fibers out of the fusion splice and put on the heat shrink protector (tube) over the joint where the fibers are spliced. Put the spliced fibers (with protector tube) into the heat shrink oven and allow the oven to shrink the tube around the splice point.
