C. Crimping
(Figures 14 and 15)
Only use Die Set 492783--1 to terminate 900--
m
m
easy strip or semi--tight buffered 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 fiber so that the end is even with the front of
the arm of the cable holder assembly, 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
installed in Step 5 of Paragraph 5.5.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 handles of the hand tool until the
ratchet releases. Allow the handles to open fully.
Slowly close the handles until you hear 2 clicks
from the ratchet.
4. Remove the termination cover from the
connector assembly, and retain.
5. With the connector assembly in the cable holder
assembly, position the ferrule in the upper cavity of
the front die and the plunger in the upper cavity of
the rear die. See Figure 14, Detail C.
The arrows marked on the front die indicate the
direction that the ferrule 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. Refer to
Figure 14, Details C and D.
6. Gently push the fiber toward the connector
assembly 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
from the dies.
7. Position the plunger of the connector assembly
in the first (smallest) cavity of the front die with the
knurl against the edge of the groove in the die and
the ferrule pointing in the direction of the arrow.
See Figure 14, Detail D.
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.
9. Slide the crimp eyelet up to, and until it butts
against, the connector assembly.
10. Slide the clear tubing with the inner eyelet into
the crimp eyelet until the circumferential line is
aligned with the end of the crimp eyelet. See
Figure 15, Detail A.
11. While maintaining the position of the clear
tubing relative to the crimp eyelet, position the
crimp eyelet against the last cavity of the front die
with the ferrule pointing in the direction of the
arrow. Make sure the connector assembly is
against the die and the circumferential line on the
clear tubing is aligned with the opposite end of the
crimp eyelet. The crimp eyelet will move into the
cavity when the dies are closed. See Figure 15,
Detail B.
12. Slowly squeeze the tool handles together until
the ratchet releases. Allow the handles to open
fully.
13. Install the termination cover onto connector
assembly.
14. Open the cable clamp of the cable holder
assembly, and remove the fiber from the clamp.
Slide the strain relief over the crimp eyelet until it
butts against the connector assembly. See Figure
15, Detail C.
15. Remove the connector assembly from the
cable holder assembly.
16. Align the key of the connector housing with the
chamfered edges of the connector assembly, and
slide the housing over the assembly until it snaps
in place. See Figure 15, Detail D.
DO NOT force the components together. They
are designed to fit only one way.
The assembly procedure for 900--
m
m easy strip or
semi--tight buffered fiber is now complete.
