The Method of Splicing Machine/fusion splicing normally involves heat to melt or fuse the ends of two optical fibers together. The splicing process begins by preparing each fiber end for fusion.
Below are Mention the instruction of Splicing Machine or fusion splicing:
Step 1: Stripping the fiber:
Stripping is the act of removing the protective polymer coating around optical fiber in preparation for fusion splicing. The splicing process begins by preparing both fibers ends for fusion, which requires that all protective coating is removed or stripped from the ends of each fiber.
Step 2.Cleaning the fiber: The customary means to clean bare fibers is with alcohol and wipes
Step 3. Cleaving the fiber: The fiber is then cleaved using the score-and-break method so that its end-face is perfectly flat and perpendicular to the axis of the fiber. The quality of each fiber end is inspected using a microscope. In Splicing Machine/fusion splicing, splice loss is a direct function of the angles and quality of the two fiber-end faces. The closer to 90 degrees the cleave angle is the lower optical loss the splice will yield. The quality of the cleave tool being used is critical.
Splicing the fibers – Current fusion splicers are either core Alignment Fusion Splicer or cladding alignment Splicing Machine. Using one of these methods the two cleaved fibers are automatically aligned by the fusion splicer in the x,y,z plane, they are fused together.
Prior to the removal of the spliced fiber from the fusion splicer, a proof-test is performed to ensure that the splice is strong enough to survive handling, packaging and extended use. The bare fiber area is protected either by recoating or with a splice protector. A splice protector is a heat shrinkable tube with a strength membrane and less loss.
