This part gives instructions on how to achieve low splice loss in
different environment conditions .
a) The recommended parameter group is decided according to
the fiber gap of arc test. The gap length: 015~025.
b) P arameter modification in different circumstance s.
Modify the pre-fusion c u rrent and the fusion c u rrent in the
discharge parameter group, and make the value of arc test meet
the requirements in step b , thus gaining a low loss . The
parameters will reduce at a high temperature and increase at a
low temperature.

Step 1 : Before splicing, thread the fiber through the optical
fiber protection sleeve.
Step 2 : Remove fiber coating, and then brush the bare fiber
with alcohol-soaked cotton swab. The typical bare
fiber length is 20mm.The concentration of the alcohol
should heavier than 905.
Step 3 : Cut the bare fiber using the cleaver. The typical value
of the cleaver length is 10mm~16mm.
Step 4 : Open the shield and fiber holder clamp carefully. Set
the fiber in the V-groove and the fiber holder on the
holder mount. At the same time, note that the tip of
the bare fiber does not touch anything. Make sure
fiber is at the bottom of the V-groove. If not, reset the
fiber.
