4.03 Gently continue pushing the fiber into the splice until
resistance is felt. When fully inserted, the first fiber should be
straight or have a slight bow – up to .1 inch (3 mm).
Note: If properly inserted, bare glass should not be visible
outside of splice. If bare glass is visible, pull back slightly
on fiber and continue insertion until resistance is met.
Never
fully remove fibers from splice after initial
insertion. Do not pull on fiber after it has been properly
inserted.
4.04 Prepare second fiber (strip, clean and cleave) as described in
Section 3.
4.05 Lay fiber into foam retention pad and begin to insert the fiber
end into the splice, as in 4.01 and 4.02.
4.06 Gently push the second fiber in small increments straight
through the alignment guide into the fiber entry port. As the
coating of the second fiber enters the fiber entry port, watch
for the bow in the first fiber to increase. This occurs when the
end face of the second fiber contacts the first fiber and pushes
the first fiber slightly back out of the splice. Continue gently
pushing the second fiber until it meets resistance.
4.07 Following proper insertion, the second fiber will be
approximately straight, but may have up to a .1 inch (3 mm)
maximum bow. At this point, the first fiber will have a larger
bow than the second fiber and larger than it had initially.
4.08 Push the first fiber back against the second fiber until there
are equal bows in both fibers.
Note: Do not
pull on either of the fibers following
establishment of the bows in the first and second fibers.
The fiber ends must be held together by the compressive
forces induced by the bows to produce a low loss splice.
If fiber bows are NOT observed to move as described,
repeat steps 4.02 – 4.07 of Splice Assembly but DO NOT
fully remove fibers from the splice. If bow movement is
still not observed, remove fibers, strip, clean and re-
cleave, checking for proper cleave length. Re-splice per
splicing procedure using a new splice.
Do not attempt to "tune" or optimize the splice as this
may result in higher splice loss. The Fibrlok
™
II Splice is
not designed to be "tuned." Fiber alignment does not
occur until the splice is activated.
