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.
