  2. Fibre Optic technicians, who are involved in LAN and telecommunication projects, are knowledge about fibre splicing machines. Basically it involves the joining of two fibre optic cables. This method of fibre joining is called connectorization. • A fibre optic splicer employs an electric arc to soften end faces of two optical fibre cables and join them to form single long cable. Generally, fibre splicing results in low light loss and noise reflection. It has become the most preferred method, where cables are too long.

  3. How fusion optic splicer works? • Before fusion is applied, the cables have to be stripped of their external jacket and polymer coating carefully. Then they are cleaned thoroughly and cleaved precisely to form perpendicular and smooth end faces. After completing this initial process, each fibre is set inside a holder included in the fibre splicer enclosure. Now, the fibre optic splicer equipment takes over the process.

  4. Alignment - The fusion splicer uses small and precise motors to make microscopic adjustments to position the fibres until they are all properly aligned. This helps the finished splice to be seamless. • Impurity burn-off - Slight trace of impurities or dust can inflict disorder on the splice’s capacity to broadcast optical signals. Even though the fibres are cleaned manually before they are inserted within the splicing device, several fusion splicers have included an extra protective cleaning step. Before fusing, a small spark is generated between the fibre cable ends to burn-off dust residue or moisture.

  5. Fusion - After proper alignment along with burning off dust and moisture, the next step is to join both the fibre ends. A large spark is emitted, which melts the ends. The fibre cladding and core of molten glass are kept separate. This is regarded as good splice because it decreases optical loss. The softened fibre tips are joined together to form the ultimate fusion splice. • Protect the fibre - The fibre needs protection against bending. Tensile force between 0.5 lbs and 1.5 lbs ensures that the splice will not fracture during normal handling. However, for more protection against pulling forces and excessive bending silicone gel, heat shrink tubing and mechanical crimp protectors are used. Thus, the splice gets protection from external elements and breakage.

  6. Tips for good splices • Thoroughly and regularly, clean your splicing device. When you are working on fibres, remember that particles are not visible to your naked eye and can cause extreme issues. Even excessive cleaning of fibre optics manually before splicing saves your money, time and effort down the road.
