CommScope LightCrimp Plus LC User manual

Figure 1
LightCrimp Plus LC simplex and duplex fiber optic
connector kits are designed to be applied to fiber
optic cable. The connectors are used with singlemode
or multimode 125– m glass fiber cable. These kits
can be used with any of the following media
(paragraph of assembly procedure is indicated
next to media).
Read these instructions thoroughly before assembling
the connector kit.
Reasons for reissue of this instruction sheet are
provided in Section 8, REVISION SUMMARY.
The simplex connector kit consists of a connector
assembly, short boot, and tubing. The tubing is used
with 250– m coated fiber. Also included, assembled
onto the connector, are a termination cover for the
ferrule (front of connector) and a protective cap for
the plunger (rear of connector). The duplex connector
kit consists of two of each of these components and a
duplex clip. The duplex clip is also available
separately.

1. Discard the tubing.
2. Slide the short boot (small diameter end first)
over the buffer. See Figure 2, Detail A.
3. Remove the rear protective cap from the
connector assembly, and discard.
4. Push the connector assembly into the holder of
the cable holder assembly with the termination
cover facing outward, making sure that the
connector butts against the lip on the arm of the
cable holder assembly. See Figure 2, Detail B.
5. Slide the buffer into the channel marked
“BUFFER”. Make sure that the tip of the buffer
butts against the end of the channel. Mark the fiber
at each cross–slot of the channel. See Figure 2,
Detail B. Then, remove the fiber from the cable
holder assembly.
For easy strip buffered fiber
, using the strip tool,
notch the fiber at the first mark. Then, grasp the
cut end of the fiber and, using a gentle pulling
motion, remove the buffer. If using the stripper,
notch the fiber at the first mark, then pull the buffer
off with the stripper. Strip the coating to the end of
the buffer with a single pass of the tool. If the
coating slides out relative to the buffer, carefully
push it back to the original position (flush with the
buffer). See Figure 2, Detail C.
For tight buffered fiber
, using the strip tool or
stripper, strip the fiber to the first mark. It is
recommended stripping the fiber in three sections.
See Figure 2, Detail C.
6. Clean the fiber with isopropyl alcohol and a
lint–free cloth to remove the fiber coating residue.
1. Open the fiber clamp of the fiber optic cleaver.
Press the button, and slide the carriage back
(toward the fiber clamp). Then move the fiber slide
back until it stops.
2. Place the stripped fiber into the slot so that the
end of the buffer is at the 8–mm marking. See
Figure 3, Detail A.
3. While applying pressure on the buffer, carefully
slide the fiber slide forward (toward the carriage)
until it stops. See Figure 3, Detail B.
4. Gently close the fiber clamp, and slide the
carriage forward. DO NOT touch the button while
sliding the carriage. See Figure 3, Detail C.
5. Open the fiber clamp, and move the fiber slide
back until it stops.
6. Remove the cleaved fiber, and properly dispose
of the scrap fiber.
1. Open the cable clamp of the cable holder
assembly, and position the fiber (with the cleaved
end facing the connector) inside the clamp. Move
the buffer so that the end of the fiber is even with
the front of the arm of the cable holder assembly,
and holding the buffer in place, close the clamp.
See Figure 4, Detail A.
2. Carefully insert the fiber into the plunger of the
connector assembly until the fiber bottoms against
the internal fiber. Make sure that the remaining
mark on the buffer enters the plunger. The
resultant bend in the fiber should hold the fiber
against the internal fiber. See Figure 4, Detail B.

3. Squeeze the handles of the hand tool until the
ratchet releases. Allow the handles to open fully.
Slowly close the handles until you hear 3 clicks
from the ratchet.
4. With the connector assembly in the cable holder
assembly, position the termination cover in the
upper cavity of the front die and the plunger in the
upper cavity of the rear die. See Figure 4, Detail C.
5. Gently push the buffer toward the connector
assembly to make sure that the fiber is still
bottomed, then slowly squeeze the tool handles
together with both hands until the ratchet releases.
Allow the handles to open fully, and remove the
connector from the dies.
6. Position the plunger of the connector assembly
in the cavity of the front die with the knurl against
the edge of the groove in the die and the
termination cover pointing in the direction of the
arrow. See Figure 5, Detail A.
7. Slowly squeeze the tool handles together until
the ratchet releases. Allow the handles to open
fully, and remove the connector assembly from the
die.
8. Open the cable clamp of the cable holder
assembly, and remove the fiber from the clamp.
Slide the short boot over the plunger until it butts
against the connector assembly. See Figure 5,
Detail B.
9. Remove the connector assembly from the cable
holder assembly.
10. For the duplex connector kit, refer to Figure 5,
Detail C, and install the duplex clip as follows:
a. Center the channel “A” connector between
the duplex clip opening marked “A” with the
recess in the connector aligned with the rib of
the duplex clip. Make sure that the termination
cover (of the connector) is pointing in the
direction of the arrow on the duplex clip.
b. Using a biasing force, push the connector
into the opening until there is an audible “click.”
DO NOT force the connector onto the duplex
clip.
c. Center the channel “B” connector between
the duplex clip opening marked “B” with the
recess in the connector aligned with the rib of
the duplex clip. Make sure that the termination
cover (of the connector) is pointing in the
direction of the arrow on the duplex clip.
d. Repeat Step b.
If connecting connectors, remove the termination
cover, and inspect the ferrule end face for
cleanliness using microscope kit and 1.25 mm
universal adapter.

1. Slide the short boot (small diameter end first)
over the fiber. See Figure 2, Detail A.
2. Remove the rear protective cap from the
connector assembly, and discard.
3. Insert the tubing into the plunger of the
connector assembly until the tubing bottoms. See
Figure 2, Detail A.
4. Push the connector assembly into the holder of
the cable holder assembly with the termination
cover facing outward, making sure that the
connector butts against the lip on the arm of the
cable holder assembly. See Figure 2, Detail B.
5. Slide the fiber into the channel marked
“BUFFER”. Make sure that the tip of the fiber butts
against the end of the channel. Make sure that the
tubing does not fall out of the connector assembly.
Mark the fiber at each cross–slot of the channel.
See Figure 2, Detail B. Then, remove the fiber
from the cable holder assembly.
6. Using the strip tool or stripper, strip the fiber to
the first mark using a single pass. See Figure 2,
Detail C.
7. Clean the fiber with isopropyl alcohol and a
lint–free cloth to remove any coating residue.
1. Open the fiber clamp of the fiber optic cleaver.
Press the button, and slide the carriage back
(toward the fiber clamp). Then move the fiber slide
back until it stops.
2. Place the stripped fiber into the slot so that the
end of the coating is at the 8–mm marking. See
Figure 3, Detail A.
3. While applying pressure on the fiber, carefully
slide the fiber slide forward (toward the carriage)
until it stops. See Figure 3, Detail B.

small tubing that was installed in Step 3 of
Paragraph 5.1.A. Make sure that the start of the
fiber coating is not caught on the entry of the small
tubing. and that the remaining mark on the fiber
enters the plunger. The resultant bend in the fiber
should hold the fiber against the internal fiber. See
Figure 4, Detail B.

connector that will not be removed or the duplex
clip.
2. With the other hand, grasp the connector to be
removed and, using a rotation motion,
gently
