(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.

DO NOT attempt to clean the fiber after it has

been cleaved.

C. Crimping

(Figures 4 and 5)

1. Open the cable clamp of the cable holder, and

hold the fiber (with the cleaved end facing the

connector) inside the clamp. Pull the end of the

fiber even with the front of the arm of the cable

holder, and holding the fiber 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 fiber enters the plunger. The resultant

bend in the fiber should hold the fiber against the

internal fiber. See Figure 4, Detail B.

Also, the fiber coating must enter the small tubing

that was installed in Step 3 of Paragraph 5.2.A.

Make sure that the start of the fiber coating is not

caught on the entry of the small tubing.

It is important that the fiber bottoms against, and

remains against, the internal fiber. If the mark

does not enter the plunger or if the fiber does not

seem to bottom against the internal fiber, the

fiber may be caught on internal guides. Rotating

the connector and backing the fiber out a small

amount and re--entering may help. However, if

the mark will not enter the plunger, the fiber must

be re--stripped.
Make sure that the fiber does not pull rearward

from the contact (with the internal fiber) during

the crimping operation.

3. Squeeze the tool handles of the hand tool until

the ratchet releases. Allow the handles to open

fully. Slowly close the handles until you hear three

clicks from the ratchet.

4. With the connector assembly in the cable

holder, position the ferrule protective cover in the

upper cavity of the front die and the plunger in the

upper cavity of the rear die. It is important to make

sure that the tip of the plunger sits in the channel

of the rear die with the protruding disk of the

plunger flat against the wall of the cavity. If the

plunger is not positioned correctly, it will be

crushed when the tool is actuated. See Figure 5,

Detail A.

The arrows marked on the front die indicate the

direction that the ferrule protective cover must be

pointing when the connector is positioned in that

cavity. For proper placement, and to avoid

damage to the fiber, the direction of the arrows

must be observed. Refer to Figure 5, Details A

and B.

5. Gently push the fiber toward the connector to

make sure that the fiber is still bottomed, then

slowly squeeze the tool handles together until the

ratchet releases. Allow the handles to open fully,

and remove the connector assembly from the dies.

6. Position the plunger of the connector assembly

in the first (smallest) cavity of the front die with the

shoulder of the plunger against the edge of the

groove in the die and the ferrule protective cover

pointing in the direction of the arrow. See Figure 5,

Detail B.

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, and

remove the buffer from the clamp. Slide the bare

buffer boot over the plunger until the boot butts

against the connector. See Figure 5, Detail C.

9. Remove the connector assembly from the cable

holder.

The assembly procedure for 250--

m

m coated fiber is

now complete.
