DO NOT attempt to clean the fiber after it has
been cleaved.
C. Crimping
(Figures 14, 15, and 16)
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 14, Detail A.
2. Holding the 250--
m
m fiber coating, carefully
insert the fiber into the plunger of the connector
assembly until the fiber bottoms against the
internal fiber. Make sure that the second mark on
the coating enters the plunger. The resultant bend
in the fiber should hold the fiber against the internal
fiber. See Figure 14, Detail B.
Also, the fiber coating must enter the small tubing
that was installed in Step 4 of Paragraph 5.4.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.
When feeding the fiber into the connector, hold
the fiber of the fiber coating to ensure that the
fiber feeds into the connector. If the fiber is
gripped by the buffer tube, the fiber will slide
rearwards into the buffer tube and will
NOT
contact the internal fiber.
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 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 15,
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 15, 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
15, 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. Slide the clear tubing with the inner eyelet
against the end of the plunger. Slide the crimp
eyelet over the clear tubing and against the rear of
the connector. See Figure 15, Detail C.
9. Position the large diameter end of the crimp
eyelet in the last (largest) cavity of the front die
with the ferrule protective cover pointing in the
direction of the arrow. See Figure 16, Detail A.
Slowly squeeze the tool handles together until the
ratchet releases. Allow the handles to fully open.
10. Position the small diameter end of the crimp
eyelet in the middle cavity of the front die with
ferrule protective cover pointing in the direction of
the arrow. See Figure 16, Detail B.
11. Slowly squeeze the tool handles together until
the ratchet releases. Allow the handles to open
fully, and remove the connector assembly from the
die.
12. Open the cable clamp of the cable holder, and
remove the buffer (cable) from the clamp. Slide the
strain relief over the plunger until it butts against
the connector. See Figure 16, Detail C.
13. Remove the connector assembly from the
cable holder.
The assembly procedure for 900--
m
m easy strip or
semi--tight buffered fiber is now complete.
