3.3 For 900 µm, determine if the fiber is tight or semi-
tight buffer. If the 900 µm slides easily from the fiber,
it is semi-tight buffer fiber. If not, it is tight buffer.
Break-out kits for 250 µm are semi-tight. Make note
of tight or semi-tight for step 3.11.
3.4 For semi-tight 900 µm buffer only, place a second
fiber holder 300 mm (12 inches) from the end of the
fiber. Latch the buffer clamp closed to ensure a stable
cleave length.
3.5 Test the stripped fiber for weak points by using your
finger to slowly flick the fiber in multiple directions.
Watch for the fiber to spring back to the straight
position. If the fiber breaks, properly dispose of the
broken-off piece and re-strip the fiber.
3.6 Thoroughly clean the stripped fiber with a lint-free
wipe and alcohol or cleaning fluid. For 250 µm
fiber at cold temperatures, use a new lint-free cloth
for each stripped fiber. Otherwise the particles on
the fiber can snag when inserting the fiber into the
connector.
Note: Carefully follow safety, health and environmental
information given on the product label or the
Material Safety Data Sheet for the isopropyl alcohol
or cleaning fluid.
3.7 Lay the 900 µm fiber into the larger of the 2 tracks
on the cleaver. Cleave it to 24 mm, by aligning the
coating edge with the left-most line on the fiber track.
Lay the 250 µm fiber into the smaller track on the
cleaver. Cleave it to 19 mm using the middle line. (If
you are using another cleaver model or one from the
3M
™
No Polish Connector Kit, then mark it at
24 mm and 19 mm.)
