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.)
