There are two types of fusion splicing methods in use throughout thtoday:• Mass fusion• Single fusion.Mass fusion splicing is for splicing multiple fibres, such as ribbonin one operationSingle fusion splicing joins the fibres one at a time. Near perfect splices can be obtained with losses as low as 0.02 dB mechanical splice 0.2 dB).Fusion splices give very low back reflections and are preferred fofibres.Fusion splicing uses expensive equipment and provides cheap splicesmechanical splicing uses less expensive equipment but provides moresplices.5.6.3 Splicing defectsSplicing defects are illustrated in FigureFigure 19.
