3.3For 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.

3.4For 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.

3.5Test 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.

3.6Thoroughly 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.

3.7Lay 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.)
