1. INTRODUCTION

This instruction sheet describes the installation of

LightCrimp Plus LC Connectors (Figure 1) to 2.0--mm

loose--jacketed, 900 μm--buffered fiber.

Please read these instructions thoroughly before

starting terminations.

Reasons for revision can be found in Section 7,

REVISION SUMMARY.

2. DESCRIPTION

Each LightCrimp Plus LC Connector consists of a

termination cover, a rear protective cap, the main

connector assembly, the crimp eyelet, and the boot.

RefertoFigure1toseetheseitems.

3. SAFETY PRECAUTIONS

To avoid personal injury, ALWAYS wear eye

protection when working with optical fibers.

NEVER look into the end of terminated or

unterminated fibers. Laser radiation is invisible

but can damage eye tissue. NEVER eat, drink, or

smoke when working with fibers. This could lead

to ingestion of glass particles.

Be very careful to dispose of fiber ends properly.

The fibers create slivers that can easily puncture

the skin and cause irritation.

DO NOT use damaged tools. Replace them with

new components.

5. ASSEMBLY

5.1. Preparing the Fiber

1. Slide the boot over the jacket as shown in

Figure 2. Place a clamp approximately 200 mm

[8 in.] from the end of the cable ---- behind the boot

(depending on the type of cable used).

2. Place the cable into the cable channel on the

cable holder and mark it at the first and second

slots as shown in Figure 3.

Important: When terminating to zip cord cable,

be sure to mark both strands at the same time.

This is required to assure maximum cable

retention performance.

Figure 3

Mark the Cable

3. Use the combination strip tool to cut the jacket

at the first mark from the cable edge and remove

thejacket.SeeFigure4.

Figure 4

4. Use shears to cut the strength members flush

with the jacket. See Figure 5.

Figure 5

5. Slide the cable into the slitting tool until the

second mark is aligned with the blades as shown in

Figure 6. Squeeze the handles and pull to slit the

jacket.

Figure 6

6. Fan back the jacket and strength members.

7. Slide the eyelet over the strength members as

shown in Figure 7.

Figure 7

8. Place the buffer on the buffer channel of the

cable holder. Mark the buffer at the two slots as

shown in Figure 8.

Mark the Buffer

9. Use the combination strip tool to strip the buffer

to the first mark. You should strip it in smaller

sections multiple times.

10. Use a lint--free cloth (dampened with alcohol)

to clean the the fiber and remove any residue.

Wipe AWAY from the buffer. If the fiber breaks, cut

the buffer flush with the jacket and begin the “strip”

process again, beginning with Step 2 in Section

5.1.

Multiple wipes will ensure cleanliness and also

trensile tests the fiber.

Do not lay cable down! Going directly to the next

step will prevent the cleaned fiber from

becoming contaminated.

Figure 9

5.2. Cleaving

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 buffer into the slot so that the

end of the fiber is at the 8--mm marking. See

Figure 10.

Figure 10

8mm

3. While applying pressure on the fiber, carefully

slide the fiber slide forward (toward the carriage)

until it stops. See Figure 11.

Figure 11

4. Gently close the fiber clamp and swiftly slide the

carriage forward. DO NOT touch the button while

sliding the carriage. See Figure 12.

Figure 12

Do not touch or attempt to clean the fiber after

the cleave has been made.

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.

5.3. Crimping

1. Place the connector in the holder as shown in

Figure 13.

Figure 13

2. Clamp the jacket with the tip of the fiber

positioned at the back edge of the holder.

3. Carefully insert the fiber into the back of the

connector until the fiber bottoms against the

internal fiber. Make sure that the remaining mark

on the buffer enters the plunger

It is VERY IMPORTANT that the prepared fiber

bottoms and stays against the internal fiber! If

the remaining mark does not enter the plunger or

if the fiber does not seem to bottom against the

internal fiber, gently pull back and re--insert the

fiber into the plunger until you feel it bottom.

If the remaining mark will not enter the plunger,

the fiber must be re--stripped.

4. Slowly squeeze the tool handles together until

the ratchet releases. Allow the handles to open

fully. Slowly close the handles until you hear two

clicks from the ratchet.

5. With the connector assembly in the cable

holder, position the termination cover in the upper

cavity of the front die and the knurled rear body in

the upper cavity of the rear die. See Figure 14.

The arrows marked on the front die indicate the

direction that the termination cover must be

pointing when the connector is positioned in that

cavity. For proper placement, and to avoid

damage to the fiber, observe the direction of the

arrows.

Figure 14

6. 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. See Figure 15.

Figure 15

7. Position the back 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.

8. Slowly squeeze the tool handles together until

the ratchet releases. Allow the handles to open

fully, and remove the connector assembly from the

die. See Figure 16.

9. Pull back the eyelet and fan out the jacket and

strength members over the connector knurled

body. See Figure 17.

members. The KEVLAR strength members and

jacket should protrude as shown in Figure 18

Excess KEVLAR fiber and jacket may be

trimmed with a shears (1278637--1), if desired.

11. Position the connector in the die (as shown in

Figure 19) and squeeze the tool handles.

12. Unclamp the jacket and slide the boot onto the

back of the connector. See Figure 20.
