2.4
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.
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.

3.3
3.4
For 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.
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.)

3.12 Move shuttle forward. Leave at least one finger width
of buffer extending beyond the nozzle. Hold the
buffer at both ends of the fiber holder, pull the fiber
straight, and set the fiber in the center tracks. Close
the back lid, but don't latch it. Close the front and
middle lid.
3.13 Snap the front and middle lids shut. Push the shuttle
forward again until it stops.

3.14 Rotate the fiber so the fiber curl is directed
downward in the fiber holder.
3.15 Hold fiber at rear, and pull the fiber backward.
Position the fiber so the tip is flush (±1 mm) with the
end of the nozzle.

Note: The 900 µm coating edge can be seen through a
hole in the shuttle. Viewing this is a good method
to check that the cleave length is correct (24 mm).
For 250 µm, the edge cannot be seen through the
hole, since it has a 19 mm cleave length.

4.0 Fiber Insertion and Connector Activation
4.1
Grip the back of the fiber holder. Do not grip the front
or middle lids, because they may need to pop open.
Slowly insert the fiber holder (with cleaved fiber) into
the guide track on the protrusion setting tool until it
reaches a stop. Do not push or pull the back end of
the fiber holder upward or downward while inserting
it, because it can influence the front lid's reaction.
SLOW, >5 seconds
Note: Insert the fiber 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. Just prior
to the fiber holder being fully inserted into the protrusion
setting tool, 1 or 2 lids, depending on fiber stiffness, will
pop open and the fiber will bow.
Don't grip
middle lid
4.2
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.
Note: 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.
Approx. 1 mm of fiber visible
Note: There are many brands and types of 900 µm coated fiber. With 900 µm fiber, 1 or 2 lids on the fiber holder will
pop open, depending on soft or stiff coating.
4.3
For soft-coated 900 µm fiber, only the middle lid will pop open. For stiff-coated 900 µm fiber, the fiber bow is strong
enough to pop open both the front and middle lids. In hot weather or when using 900 µm break-out tube kits, the
middle lid may not pop open. In that case, for 900 µm open the middle lid by hand before going to the next step. In
cold weather some coatings will become more stiff.

4.4
For 250 µm only, the fiber will bow in the nozzle slot.
No lids will open with 250 µm.
Note: Bowing these 3 different fiber coating types at 3
different lengths enables consistent fiber protrusion setting.
250 µm coating
4.5
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. Hold onto the lever, keeping it
from springing forward on its own.
4.6
CRITICAL STEP: Watch for the fiber bow to increase
slightly as the lever comes down. Do not proceed to
the next step until seeing this. It is easiest to see the
bow increase from a side view rather than a top view.
Watch for fiber bow

Note: The fiber bow increase is caused by the lever moving
the jig tip which pushes the fiber backward.

4.7
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.
Push hard
Note: Never activate a connector without a fiber in it or
with a fiber only partially inserted. Doing so will ruin the
connector by blocking fiber from being fully inserted.
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.
Not crimped

4.8
For 900 µm only. CRITICAL STEP: If you have
the 3M™ 200X View Scope 6365-VS for end face
inspection, skip this step (4.8) until after step 5.8,
connector cleaning is complete. If you don’t have
the optional view scope accessory, activate the buffer
strain relief within the connector using the shuttle
on the fiber holder. While holding the entire tool
in place, press the release lever on the side of the
protrusion setting tool base and push on the two ears
of the shuttle (toward the connector) until it reaches
its travel limit.
2. Push ears
1. Release lever
900 µm
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. There are no provisions to deactivate
the 900 µm buffer strain relief within the connector. The
grip strength will be relatively low for thin-wall, 900 µm
break out tube kits, compared to standard 900 µm buffer.

4.9
Open the covers and buffer clamp (if necessary) on the fiber holder (for stiff-coated fiber, the buffer clamp was
already opened). Slide the fiber holder out of the guide track in the protrusion setting tool, leaving the connector
and fiber behind.
4.10 Remove the connector from the port on the protrusion
setting tool. Use care to protect the ferrule and fiber
tips from damage.
5.0 Nano-finishing and Cleaning
5.1
Complete the installation process using the 3M™ Nano-
finisher. 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 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.
5.3
Insert the connector into the port on the 3M™ Nano-finisher lid making certain it is fully engaged. Push until a click
is heard.

5.4
Press the release button on the side of the finisher.
The button will stay depressed until the finishing
sequence is complete. It pops back up automatically.
Allow this to happen by keeping clear of the button
during the sequence.
5.5
5.6
Rotate the input knob one full turn with a single
continuous motion. The finisher automatically stops
the input knob after one full turn.
Remove the connector from the port on the
finisher lid.
Note: The nano-finisher is best stored dry – inside and out.
Open the lid as shown in step 5.1, and allow to dry.

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.
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.

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 re-insert the connector into the protrusion
setter and activate the buffer clamp per step 4.8. If the
connector needs rework, proceed to Section 6.0.
Chips or cracks inside the 1/2 diameter circle are not allowed.

6.0 Connector Reusability
6.1
Should it become necessary to separate the connector
and fiber, e.g. to reset the fiber protrusion, the
activation cap within the connector can be deactivated.
This is accomplished by first removing the connector
from the port on the protrusion setting tool. 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.
6.2
6.3
To correct large, deep imperfections on the fiber face,
restart at step 2.0. Replace the lapping film disc for
each re-use of the connector.
To correct small, shallow imperfections, such as
small chips, reinsert the connector in the protrusion
setter. Hold the fiber with your fingers and create
a bow in the fiber. The bow length should be
approximately as shown in Step 4.3 for 900 µm,
and approximately as shown in Step 4.4 for 250
µm. Hold the fiber bow and begin completing
Steps 4.5 through 5.8. Use a new piece of lapping
film per Step 5.1.
1. Create bow
2. Actuate lever
7.0 Troubleshooting
7.1
If the fiber is not visible with the flashlight in step
4.2, and bow increase is not seen in step 4.6, check
the bow height by tilting the middle door on the
fiber holder to the vertical position, as shown in the
photo to the right. If the fiber bow is taller than the
rib in the center of the middle door, marked with
a dotted line illustrated on the right, then the fiber
bow is too high. The fiber has hit a snag inside
the connector. Remove the fiber and fiber holder
from the protrusion setter. Open the latch on the
fiber holder's buffer clamp. Re-adjust the fiber
so that fiber curl is downward as shown in step
3.12. Attempt inserting the fiber into the connector
again per section 4.0. If a high bow occurs again,
re-strip the fiber and re-cleave per section 3.0. If
the same high bow problem occurs again, mark the
connector as defective and get a new connector.
High bow problem
Soft 900 µm coating
High bow problem
7.2
7.3
If the a connector falls off 250 µm fiber, install a
new connector, and ensure that the 250 µm acrylate
has been stripped off 40 mm long, per step 3.2.
Also ensure cleave length is 19 mm per step 3.7.
Also ensure that the termination matches photos
4.2, 4.4, and 4.6.
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.
