List Different Types:-

• Fusion Splice
• V-groove Splice
• Elastic tube splice

Fusion Splice:

• It is accomplished by applying localized heating i.e by a flame or an electrical arc at interference between two butted, pre aligned fiber ends.
• This technique involves heating of two prepared fiber ends to their fusing point by applying sufficient axial pressure between the two optical fibers. For heating most widely source is electric arc. Following are steps for fusion process
• PERFUSION: It is a technique, which involves the rounding of the fiber ends with a low energy discharge before pressing the fibers together.
• By moving movable block, with proper pressure two fibers are pressed together.
• Then there will be accomplishment of splice

V-groove Splice:

• In this technique V-grooves are used to secure the fibers to be joined. This method utilizes a V-groove into which the two prepared fiber ends are pressed.
• The V-groove splice ends through insertion in the groove. The splice is made permanent by securing the fibers in the V-grooves with epoxy resin.
