Safety Precautions

Protective Eyewear

 CAUTION

To reduce the risk associated with eye injury:

- Safety glasses should be worn when handling chemicals and cleaving the optical ber.

Chemical Precautions

 WARNING

To reduce the risk associated with re:

- Storage, use and disposal of isopropyl alcohol should be per your company health, safety and environmental instructions. Refer to material safety data sheet for health hazards, safe handling, proper use and control measures.

Bare Fiber Handling

 CAUTION

To reduce the risk associated with handling sharp glass bers:

- Cleaved glass bers are sharp and can pierce the skin. Use tweezers when handling shards and dispose of them properly per your company health and safety instructions.

Fiber/Cable Handling

NOTICE

To reduce the risk associated with ber damage:

- Optical ber can be damaged by excessive tensile, compressive and bending forces. Consult the manufactures’ specications for proper handling instructions.

Laser Safety

 CAUTION

To reduce the risk associated with eye damage from exposure to laser light:

- Take the proper precautions when working with optical ber because invisible laser light may be present. The principal laser hazard when working with ber optics is injury to the eye. Never look directly into the ber or connector using the naked eye or a microscope.

1.0 Overview

1.1 3M™ Crimplok™+ Connectors 8700-UPC & APC terminate 250 µm and 900 µm singlemode fibers, and the Crimplok+ 6700 series connectors terminate 250 µm and 900 µm multimode fibers for excellent optical performance.

1.3 Additional materials needed:

• De-ionized or distilled water for nano-finishing at above-freezing temperatures

• 25% to 35% methanol by volume and 75% to 65% de-ionized or distilled water solution by volume for nano-finishing at below-freezing temperatures. DO NOT use ethanol or isopropyl alcohol for nano-finishing.

• 99% pure isopropyl alcohol (for cleaning only) or a fiber optic connector cleaning solution approved by your company.

Note: Carefully follow safety, health and environmental

information given on product labels or the Material Safety Data Sheets for isopropyl alcohol, fiber optic cleaning fluid, and/or methanol/water solution.

1.4 Optional accessory:

2.0 Connector and Protrusion Setting Tool Preparation

2.1 On the 3M™ Protrusion Setting Tool, move the actuator lever to the unactivated position as shown.

2.2 Clean the tip of the protrusion setting jig using a lint-free cleaning swab with a drop of alcohol or cleaning fluid. Reach through the window with the swab and move the swap tip vertically to clean the jig tip.

2.3 Remove the 3M™ Crimplok™+ Connector from the bag and remove the dust cap from the ferrule. Remove the lapping film disc from the bag and set it aside for later.

2.4 Insert the connector into the SC port with the actuation cap facing upward. Ensure the connector is fully seated in the port.

3.0 Fiber Stripping & Cleaving

3.1 Open both covers on the cleaver. Move the blade carriage to the front. Once per day, or whenever the cleaver gets dirty, clean the fiber groove, rubber pads and blade with the brush.

Note: Cleaver can be silver-colored or dark grey-colored.

3.2 If working with cable, strip at least 230 mm (9 in.) of cable jacket away to expose just 900 or 250 µm coating. Holding the fiber stripper perpendicular to the fiber, strip enough 900 or 250 µm coating (minimum of 40 mm) to allow the fiber to extend well beyond the second pad on the cleaver as shown in Section 3.7.

Note: Do not grip the fiber stripper with full strength, because it can damage the tool and weaken the fiber.

578-0013-1746-6-E

3.3 For 900 µm, determine if the fiber is tight or semitight 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.)
