kit consists of two of each of these components and a
duplex clip. The duplex clip is also available
separately.
3. SAFET PRECAUTIONS
To void person l injury, ALWAYS we r eye
protection when working with optic l fibers.
NEVER look into the end of termin ted or
untermin ted fibers. L ser r di tion is invisible
but c n d m ge eye tissue. NEVER e t, drink, or
smoke when working with fibers. This could le d
to ingestion of gl ss p rticles.
BE VERY CAREFUL to dispose of fiber ends
properly. The fibers cre te slivers th t c n e sily
puncture the skin nd c use irrit tion.
DO NOT use defective or d m ged components.
Repl ce them with new components.

5. ASSEMBLY PROCEDURE
5.1. 900- m m Easy Strip or Tight Buffere Fiber
A. Preparing 900- m m Buffere Fiber (Figure 2)
1. Discard the tubing.
2. Slide the short boot (small diameter end first)
over the buffer. See Figure 2, Detail A.
3. Remove the rear protective cap from the
connector assembly, and discard.
4. Push the connector assembly into the holder of
the cable holder assembly with the termination
cover facing outward, making sure that the
connector butts against the lip on the arm of the
cable holder assembly. See Figure 2, Detail B.
5. Slide the buffer into the channel marked
“BUFFER”. Make sure that the tip of the buffer
butts against the end of the channel. Mark the fiber
at each cross–slot of the channel. See Figure 2,
Detail B. Then, remove the fiber from the cable
holder assembly.
Before using the strip tool, ma e sure that the V"
opening is clean; otherwise, the fiber could brea .
Only use reagent-grade isopropyl alcohol on the
strip tool.
For easy strip buffered fiber , using the strip tool,
notch the fiber at the first mark. Then, grasp the
cut end of the fiber and, using a gentle pulling
motion, remove the buffer. If using the stripper,
notch the fiber at the first mark, then pull the buffer
off with the stripper. Strip the coating to the end of
the buffer with a single pass of the tool. If the
coating slides out relative to the buffer, carefully
push it back to the original position (flush with the
buffer). See Figure 2, Detail C.
For tight buffered fiber , using the strip tool or
stripper, strip the fiber to the first mark. It is
recommended stripping the fiber in three sections.
See Figure 2, Detail C.
6. Clean the fiber with isopropyl alcohol and a
lint–free cloth to remove the fiber coating residue.
B. Cleaving (Figure 3)
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 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
assembly, and position the fiber (with the cleaved
end facing the connector) inside the clamp. Move
the buffer so that the end of the fiber is even with
the front of the arm of the cable holder assembly,
and holding the buffer 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 buffer enters the plunger. The
resultant bend in the fiber should hold the fiber
against the internal fiber. See Figure 4, Detail B.

cavity. Fo p ope placement, and to avoid
damage to the fibe , obse ve the di ection of the
a ows. Refe to Figu e 4, Detail C and Figu e 5,
Detail A.
5. 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.
6. Position the plunger 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. See Figure 5, Detail A.
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
assembly, and remove the fiber from the clamp.
Slide the short boot over the plunger until it butts
against the connector assembly. See Figure 5,
Detail B.
9. Remove the connector assembly from the cable
holder assembly.
10. For the duplex connector kit, refer to Figure 5,
Detail C, and install the duplex clip as follows:
a. Center the channel “A” connector between
the duplex clip opening marked “A” with the
recess in the connector aligned with the rib of
the duplex clip. Make sure that the termination
cover (of the connector) is pointing in the
direction of the arrow on the duplex clip.
b. Using a biasing force, push the connector
into the opening until there is an audible “click.”
DO NOT force the connector onto the duplex
clip.
c. Center the channel “B” connector between
the duplex clip opening marked “B” with the
recess in the connector aligned with the rib of
the duplex clip. Make sure that the termination
cover (of the connector) is pointing in the
direction of the arrow on the duplex clip.
d. Repeat Step b.
To emove the connecto s f om the duplex clip,
efe to Section 6.
The assembly proce ure for 900-mm easy strip or tight
buffere fiber is now complete.
" If connecting connectors, remove the termination
cover, and inspect the ferrule end face for
