Safety Precautions
Protective Eyewear
To reduce the risk associated with eye injury:
- Safety glasses should be worn when handling chemicals and cleaving the optical fiber.
CAUTION
Chemical Precautions
To reduce the risk associated with fire:
- 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.
WARNING
Bare Fiber Handling
To reduce the risk associated with handling sharp glass fibers:
- Cleaved glass fibers are sharp and can pierce the skin. Use tweezers when handling shards and dispose of them properly per your
company health and safety instructions.
CAUTION
Fiber/Cable Handling
To reduce the risk associated with fiber damage:
- Optical fiber can be damaged by excessive tensile, compressive and bending forces. Consult the manufactures’ specifications for proper
handling instructions.
NOTICE
Laser Safety
To reduce the risk associated with eye damage from exposure to laser light:
- Take the proper precautions when working with optical fiber because invisible laser light may be present. The principal laser
hazard when working with fiber optics is injury to the eye. Never look directly into the fiber or connector using the naked eye or a
microscope.

2.0 Connector and Protrusion Setting Tool Preparation
2.1 CRITICAL STEP: Slide the boot onto the cable
being terminated.
2.2 On the 3M™ Protrusion Setting Tool, move the actuator lever to the unactivated position as shown. 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 swab 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 on the protrusion setting tool with the actuation cap facing upward.
Ensure the connector is fully seated in the port.

3.0 Fiber Stripping & Cleaving
3.1 For the Ilsintech CI-01 cleaver only, use the hex
wrench on the bottom of the cleaver to remove the
left clamp. Re-insert the screw and fasten it
partially.
3.2 For the Ilsintech CI-01 cleaver only, set the screw
head height by sliding the tip of the cable holder
underneath the screw head. The screw head can
hold the cable holder in place.
3.3 For the Ilsintech CI-01 cleaver only, open the right
cover 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.
3.3 Position the cable with the curl downward in the
cable slitter tool. The cable slitter tools have slots
labeled 1.6, 2, 2.4, and 3 mm. Use the holes on the
bottom of the cable holder to determine the cable
size. If using the 3M™ Easy Cleaver, slit the
jacket 2 finger-widths beyond the edge of the tool.
If using Ilsintech CI-01 cleaver, slit the jacket 1
finger width beyond the tool.

3.4 Group the aramid yarn together. Run your fingers
over the yarn at least twice .
3.5 Place the cable into the cable holder, with fiber curl downward. Place 3 mm cable straight down the center track.
Place 1.6–2 mm cable in an s-bend, using the far-side track on the cable holder. Align the beginning of the cable
slit with the 2 posts at the beginning of the cable track.
3.6 Close the back lid until it latches shut.
3.7 Arrange the slit jacket along the sides of the cable
holder. Pull the aramid yarn into the center of the
back lid. Close the front and middle lid.

3.8 Cut the excess jacket at the white lines marked on
the cable holder.
3.9 Slide both shuttles backward. Ensure the fiber curl
is directed downward in the fiber holder. If not,
re-arrange the cable with curl downward per step

3.10 Strip the 900 µm coating off so that it is even with
the tip of the fiber holder. Notice that one side of
the cable holder fork is longer than the other. Use
the longer of the two as a target. Also strip any
250 µm coating left behind.
Note: Do not grip the fiber stripper with full strength
because it can damage the tool and weaken the
fiber.
3.11 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 repeat the
steps starting with 3.1.

3.12 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.
3.13 Open the cover(s) on the cleaver. Once per day, or whenever the cleaver gets dirty, clean the fiber groove and
rubber pad(s) with a cleaning swab. Do not touch the diamond wire on the 3M™ Easy Cleaver. Insert the cable
holder into the cleaver.

3.14 Close the cover. Slide the shuttle across to cleave the fiber. After cleaving, open the cover. Carefully grab the
fiber shard. Use tweezers if necessary. Safely dispose of the fiber shard.
CAUTION: The glass shard is sharp and can pierce the skin.

3.15 Remove the cable holder from the cleaver. Slide
the front shuttle all the way forward.
4.0 Fiber Insertion and ConnectorActivation
4.1 Grip the back of the cable holder. Slowly insert
the cable holder (with cleaved fiber) into the
guide track on the protrusion setting tool until it
reaches a stop.
Note: Insert the cable holder slowly to avoid breaking the
fiber. This step should take 5 seconds or more.
Faster insertion can lead to breaking the fiber. As
the fiber holder slides in, the shuttle will reach a
stop, and the cleaved end of the fiber will thread
through the connector.
4.2 The cable holder will make a click sound as it
reaches a stop. Gently pull back on the cable
holder about 1 mm, release it, and watch it spring
forward into place. This indicates you are ready
for the next step. If the cable holder did not click
or does not spring forward, see the
Troubleshooting section (7.0).
4.3 Verify that the cleaved end of the fiber extends
beyond the tip of the connector ferrule. To do this,
press and hold the push button on the flashlight
contained within the protrusion setting tool, and
visually confirm the presence of approximately 1
mm of fiber through the viewing window. If for
some reason the fiber is not seen extending
beyond the tip of the connector ferrule, withdraw
the fiber holder (with cleaved fiber) from the
protrusion setting tool and repeat as many of the
preceding steps as necessary.

4.4 Rotate the activation lever on the protrusion
setting tool 180° until the free end is positioned
directly above the connector.
Note: Use caution to move the lever slowly to avoid
damaging the fiber.
4.5 CRITICAL STEP: Watch for the cable holder to
slide backward approximately 1 mm as the lever
comes down. Do not proceed to the next step until
seeing this.
Note: The cable holder slides backward, because the lever
moves the jig tip, which pushes the fiber backward.
4.6 Press down hard on the free end of the activation
lever to activate the fiber crimping mechanism
within the connector. After a click sound, the
lever will be stopped and cannot be pushed any
further.
Note: Never activate a connector without a fiber in it or
with a fiber only partially inserted. Doing so will
ruin the connector.

Push hard
Note: If you are not sure if the click was heard, and therefore not sure if the fiber is crimped, inspect the cap
surface. A raised surface indicates the fiber IS NOT crimped. A flush, even surface indicates the fiber IS
crimped.
