What is a fusion splicer?
A fusion splice is the technique of joining two fibre optic cores by melting the ends together using an electric arc. A fusion splicer is used because an extremely high degree of accuracy is required due to the small diameter of fibre optic cable and tight tolerances. The fusion splicer first aligns the cores and then applies the exact amount of heat needed to melt the ends before pressing them together and fusing the fibre to form a very low loss joint.
