Fiber Optic Fusion Splicer

The principle of fusion splicing is that the two bare fiber ends (with coatings removed) are fused together under the influence of heat. More precisely, the fiber ends are initially brought in close contact, with a small gap in between. After heating them for a short while such that the surfaces melt, they are pushed together, such that the ends fuse together.
