Cleave lengths can be confirmed on the 12.5mm length
gauge. Cleave should be within the window.
6.1 Cut off rubber band, position actuation lever over splice, and
lift both buffer clamps to the “up”position.
Confirm that buffer on pigtail is fully inserted inside
splice and follow steps 7.2 through 7.9.

7.2
Holding the fiber approximately ½ inch (13mm) from the
bare glass, insert cleaved fiber into the guide on the right
(actuation lever side) of the splice/holder until it stops inside
the Fibrlok II splice.
Carefully mark the buffer at the right edge of the base.
Note: Always insert the fiber first on the right (actuation lever
side) of the splice/holder.

Prepare second fiber (strip, clean and cleave) as described in
section 5.
7.3
Holding the fiber approximately ½ inch (13mm) from the
bare glass, insert second fiber into the guide on the left side
(opposite actuation lever) of the splice/holder until it stops
inside the Fibrlok II splice.
7.4
While sliding the second fiber into the splice, the mark on the
first fiber should move outwards 1/8 inch (3mm) showing the
fiber ends are in contact. If this is not observed, one or both
fibers has a bad/short cleave. Remove one fiber and re-strip,
clean, re-cleave and insert back into the splice. If contact is
still not correct, repeat procedure for second fiber.
7.5
Note: To prevent contamination, never fully remove and re-
insert a cleaved end back into a splice without first re-stripping
and re-cleaving.
Center both fiber cleaves by repositioning the mark on the first
fiber half way back to its original position.
7.6
Note: Cleavers must be in good operating condition and used per the manufacturer’s instructions. They
should provide consistent cleave-to-coating lengths /- 0.5mm. Acceptable cleavers will produce
cleaved ends within 0.5° of perpendicular (typical always <1 °), free from major defects.
6.0
7.1
Note: Push fiber straight into the fiber alignment guide, not at
an angle. Bare glass should not be visible outside of the splice. If
bare glass is visible, pull back slightly on the fiber and continue
insertion until resistance is met. Do not fully remove fibers from
splice after initial insertion.
Once the fibers are centered, fully close the right buffer clamp.
You will hear an audible snap.
