(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.
