An optical fibre fusion machine, also known as a fusion splicer, is a precision instrument used to permanently join two optical fibres by aligning and fusing their ends using an electric arc. It consists of high-resolution alignment cameras, precision fibre holders, motorized alignment mechanisms, an arc fusion electrode system, a heating oven for splice protection sleeves, a digital display, rechargeable battery, and an internal processor for automatic calibration and splice analysis. The machine produces low-loss, high-strength fibre splices, making it essential for the installation, maintenance, and repair of fibre optic communication networks.

Operation:
To operate the fusion machine, the optical fibres are stripped, cleaned, and cleaved before being placed into the fibre holders. The machine automatically aligns the fibre cores using cameras and precision motors, then generates a controlled electric arc to fuse the fibre ends into a single continuous strand. After splicing, it estimates the splice loss, performs a tensile test to verify splice strength, and the protective splice sleeve is heat-shrunk in the built-in oven to safeguard the joint. Regular cleaning of the electrodes, fibre holders, and optical components, together with periodic calibration and battery maintenance, ensures accurate, reliable, and consistent splicing performance.
