⚫ A vertical line sometimes appears at the splice point when MM fibers or
dissimilar fibers (different diameters) are spliced. This does not affect
splice quality, such as splice loss or tensile strength.
6. Removing spliced fiber
a) Open lids of tube heater.
b) Open wind protector.
c) Hold left fiber with left hand at the edge of wind protector and open left
sheath clamp or fiber holder lid.
d) Open right sheath clamp or fiber holder lid.
e) Hold right fiber with right hand, and remove spliced fiber from the
splicer.
⚫ Keep on holding fiber until fiber is completely transferred to tube heater.
7. Heating protection sleeve
a) Transfer fiber with protection sleeve to tube heater. Protection sleeve is
placed in the center of the tube heater.
b) Place fiber with protection sleeve in the middle of tube heater. While
placing it in the tube heater, apply some tension on the fiber so the tube
heater lids automatically close. Then press button starting heating
