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.
Actuation Cap
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.

3.15 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.
Watch for cable
holder to slide

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.
Notcrimped Crimped

4.7 CRITICAL STEP: Activate the buffer strain relief
within the connector using the shuttle on the fiber
holder. While holding the tool in place, press the
left release lever on the side of the protrusion
setting tool base and push on the shuttle (toward
the connector) until it reaches its travel limit.
Note: This step increases the durability of the connection.
If this step is skipped, then the connector is more
likely to fall off the 900 μm fiber before the nut
and boot are attached. If needed, the 900 μm
buffer strain relief can be deactivated carefully
with a tweezers.
4.8 Rotate the protrusion setting lever up. Lift the
front 2 covers about 90° open on the cable holder.
(Opening the front 2 covers beyond 90° will cause
a snag on step 4.9.) Press the back cover latch,
and open the back cover.
4.9 Lift cable out of the track. Hold the cable slightly
above the cable holder and push the shuttle away
from the connector.
4.10 Push the cable holder completely out of the guide
track in the protrusion setting tool, leaving the
connector and cable behind.

4.11 Remove the connector from the port on the
protrusion setting tool. Use care to protect the
ferrule and fiber tip from damage.
4.12 Arrange the 2 slit jacket strands on the sides of the
connector. Route the aramid yarn on the side
opposite of the actuation cap. Pull the yarn
straight. Bring the connector boot up to the
connector body. Make sure the fiber is not
bowed.
4.13 Hold the aramid yarn straight in a bundle on underside of connector as shown in photo. Lightly pull
jacketed cable ensuring bow is fully removed. Aramid yarn should be straight but not tensioned. While
advancing boot to thread, observe that buffer does not bow. Twist boot two full rotations to partially anchor
aramid yarn. For 1.6–2 mm cable, twist the aramid yarn and allow some slack as shown.

5.1 Complete the installation process using the 3M™
Crimplok™+ SC Nano Finishing Tool. Open the
lid on the finisher by first depressing the latch. For
proper performance, only one finishing disc may be
installed at a time. Use a new disc for each
connector. Discs are provided in the connector
package. Remove the adhesive-backed finishing
disc from the protective liner, and place it onto the
backup pad. Center the disc on the pad using the
through hole and pin as visual references. Press the
disc against the backup pad while taking care to
keep it clean. Keep pressing the disc down until
there are no air pockets under it. It is okay for your
fingers to touch the polishing surface while
pressing the disc down.
5.2 Wet the top surface of the finishing disc with 2
squirts of de-ionized or distilled water using the
spray bottle provided. Avoid using excessive
amounts of water. Close the lid fully and ensure the
latch is engaged.
Note: Wetting the disc surface is important because it
carries off glass particles that have been removed.
Failure to wet the disc results in poor connector
performance.

5.5 Rotate the input knob one full turn with a single
continuous motion. It automatically stops after one
full turn.
5.6 Remove the connector from the port on the finisher
lid.
Note: The 3M™ Nano Finishing Tool is best stored dry –
inside and out. Open the lid as shown in step 5.1,
and allow to dry.
5.7 Remove the lapping film. Inspect the lapping film for fiber tracks. If the film has tracks, dispose of it. If not,
restart at step 5.1. one full turn.
APC UPC
5.8 Dry the connector using a new lint-free wipe. Do
not use the same wipe used for stripping fiber. Fold
the wipe to provide cushion. For APC, tilt the
connector so the ferrule tip is in full contact with
the wipe. For UPC, hold the connector
perpendicular to the wipe. Press the ferrule tip into
the wipe slightly and move the tip in a circular
motion. After the connector has been dried, add 1
or 2 drops of alcohol or cleaning fluid to a clean
area of the wipe. Do not mix water and alcohol or
water and cleaning fluid on the wipe. If too much
alcohol or cleaning fluid soaks the wipe, just use
the edge of the wetted area. Clean the connector by
moving the tip in a small circular motion. Then dry
the connector with a spot on the wipe that has not
been used yet, and is not contaminated with water,
alcohol or cleaning fluid. Use a small circular
motion. Finish with a twisting motion.

5.9 Before the network has a laser light source feeding
your connector, inspect the fiber end face with
3M™ 200X View Scope 6365-VS if you have one.
If the fiber end face looks acceptable per photos to
the right, then protect it with a dust cap, or insert
into its adapter. If the connector needs rework,
proceed to Section 6.0.
Caution reminder: Never look directly into the end of a
fiber or connector when connected to a laser light source
using the naked eye or a microscope.

6.0 Connector Reusability
6.1 Should it become necessary to separate the
connector and cable, e.g. to reset the fiber
protrusion, unscrew the boot from the back of the
connector.
6.2 Insert one side of tweezers between the black,
cylindrical sleeve and the connector body to pry the
sleeve backward, sliding it toward the cable.
You’ll notice a beige portion of the connector is
now re-exposed.
6.3 Place the connector atop the deactivation station on
the tool base, with the activation cap face up, and
press firmly downward. This action releases the
gripping mechanism within the connector. Limit
the number of times a given connector is reused to
one. A connector with its cap pushed down without
a fiber inside, or with a fiber only partially inserted,
is not reusable.
6.4 To correct large, deep imperfections on the fiber
face, cut the slit portion of the cable off, and restart
at step 2.0. Replace the lapping film disc for each
re-use of the connector.
6.5 To correct small, shallow imperfections, such as
small chips, reinsert the connector in the protrusion
setter, and reinsert the cable into the fiber holder
beginning in Step 3.5.
7.0 Troubleshooting
7.1 If the cable holder does not spring forward in step 4.2, then remove the cable holder from the protrusion
setting tool. Clean the track in the protrusion setting tool. Use a tweezers to ensure the connector sleeve is
moved to the rear of the connector. Continue with step 4.1.
7.2 If you can see the fiber with the flashlight as shown in step 4.3, but did not see the cable holder spring back in
step 4.5, then remove the cable holder. Check that the buffer edge lines up with the cable holder edge per step
3.10. Strip more buffer away if needed. Clean per step 3.12, skip to step 3.15, and continue with all the
following steps.
7.3 If you cannot see the fiber with the flashlight in step 4.3, and cannot see the cable holder spring-back in step
4.5, there is a chance the fiber broke inside the connector. Cut the slit cable off, and safely dispose of the
glass shard. Check if the connector’s fiber pathway is clear, by inserting a stripped piece of 900 µm fiber.
Re-start with step 2.0 using a connector that has a clear pathway or a new connector.
7.4 For APC only, if insertion loss is 2.9 dB - 3.6 dB, then inspect the lapping film per section 5.7. Polish the connector
if it has not been polished yet.
