scope n n n Types of splicing Splicing procedure Losses Comparison Manufacturers Cost
types of splicing n n Mechanical Fusion (welding)
scribe & break End preparation n Striping (cable jacket, buffer tube & coating) n Cleaving n Cleaning the end surface
mechanical splicing bonding two fibers together in an alignment structure n Transparent adhesive - e. g. epoxy resin n Commonly used groove - V-groove n Alignment problems n
fusion splicing n Fusing the two fibers Flame heating sources - micro-plasma burners, oxyhydric micro-burners, electric arc. . n Advantage - consistent and easily controlled heat with adaptability n Possible drawback - weakening of fiber in the vicinity of splice n
splice tray n n Stores and organizes the fiber & splice Protects fibers Prevents fibers from exceeding the minimum bending radius Establishes long haul links
comparison Mechanical splicing Reflection losses (-45 db to -55 db) Insertion loss (0. 2 db) cost – high Fusion splicing No reflection losses Very low insertion loss (0. 1 db to. 15 db) Comparatively less
splicing losses Intrinsic - Freznel reflection n Extrinsic - foreign particles on surfaces n Reflection - incident and reflected beam travel on the same path n
what do we achieve by splicing? n n n Clear Better appearance Greater strength
