A. Jacketed Cable
1. Slide the short strain relief (small diameter end
first) onto the cable. If the cable jacket diameter is
less than 2.5 mm [.1 in.], slide the PVC tubing onto
the cable. Slide the crimp eyelet (rolled end first)
onto the cable.
2. Refer to the “OPTIMATE 2.5mm Bayonet
(Ceramic)” strip length template (from the cable
preparation template kit) or refer to Figure 2, Detail
A, and using the cable stripper, strip the jacket to
the dimension shown. Using the shears, trim the
strength members to dimension shown. Using the
fiber stripper, strip the buffer, then the coating to the
dimension shown.

4. Evenly “fan out” the strength members from the

DANGER
ALWAYS wear safety glasses when working with optical
fibers. BE VERY CAREFUL to dispose of fiber ends
properly. The fibers create slivers that easily puncture
the skin and cause irritation.
B. 900-µm Buffered or 250-µm Coated Fiber
1. For buffered fiber, slide the bare buffer boot
(small diameter end first), crimp eyelet (rolled end
first), and clear tubing onto the buffered fiber.

clear tubing, and small diameter tubing onto the

3.4. Terminating the Fiber
1. Remove the protective cap from the connector.
Hold the connector with the knurled end up. Insert
the tip of the epoxy applicator as far as possible into
the connector body. See Figure 4, Detail A.
2. Inject the epoxy into the connector until a small
bead with a diameter of approximately 0.76 mm
[.030 in.] appears at the tip of the ferrule. DO NOT
allow the bead get too large or smear.
3. Withdraw the applicator while simultaneously
injecting the epoxy into the bore of the connector
until it is approximately three-quarters full.
4. For jacketed cable, apply a drop of epoxy to the
outside of the knurled end of the connector, and
distribute it evenly around the circumference of the
knurled end. See Figure 4, Detail B. DO NOT allow
any epoxy on the coupling nut or spring area.
5. Using a twisting motion, gently insert the fiber into
the connector until it bottoms. The fiber should
appear at the tip of the ferrule. Refer to Figure 4,
Detail C.
For jacketed cable, make sure that the strength
members are spread out evenly over the knurled
end of the connector. See Figure 4, Detail C.
6. Twist the connector, and move it back and forth
axially approximately 1.5 mm [.060 in.] to distribute
the epoxy in the bore of the connector.
7. For jacketed cable, slide the crimp eyelet toward
the connector until it contacts the connector
shoulder, trapping the strength members against
the knurled end. If using the PVC tubing, slide it
under the crimp eyelet until it bottoms. See Figure 5.
For buffered fiber, slide the clear tubing against the
back of the connector, then slide the crimp eyelet
over the clear tubing and onto the connector. See
Figure 5.
For coated fiber, slide the small diameter tubing and
clear tubing against the back of the connector, then
slide the crimp eyelet over the clear tubing and onto
the connector. See Figure 5.
NOTE
stripper), see instruction sheet 408-9485.
3. Clean the fiber thoroughly using an alcohol fiber
wipe.
3.3. Preparing the Epoxy
1. Remove the separating clip from the epoxy
package, and mix the epoxy thoroughly for 20 to 30
seconds.
2. Install the needle tip on the epoxy applicator.
Make sure it is secure. Remove the plunger.
3. Cut the epoxy packet open, and squeeze the
epoxy into the back of the applicator. Re-assemble
the plunger. Hold the applicator vertically, and
slowly push on the plunger until the entrapped air
escapes and a bead of epoxy appears at the tip.
i
NOTE
NOTE
An alternate method in preparing the epoxy is as
follows:
1. Remove the tip of the epoxy applicator by twisting it
one-quarter turn and pulling it away from the body of the
applicator.
2. Install the open end of the epoxy applicator into the
epoxy, and pull back on the plunger to draw epoxy into
the applicator. See Figure 3.
3. Slide the tip onto the applicator, making sure it is
firmly secured. Hold the applicator vertically, and slowly
push on the plunger until a bead of epoxy appears at the
tip.

!
CAUTION
Make sure to crimp the connector before the epoxy
cures.
1. Position the connector in the die assembly as
shown in Figure 6.
NOTE
i
On all multi-fiber cable where the fibers lie in a plane,
NOTE
position the connector alignment keys in the same
orientation during crimping.

3. Slide the protective sleeve onto the connector,

4. Clean excess epoxy from the connector, tool, and

5. Taking care not to break the protruding fiber,
firmly hold the front of the connector, and slide the
short strain relief or bare buffer boot over the crimp
eyelet and onto connector shoulder until it bottoms.
3.6. Curing the Epoxy
1. Hang the connector vertically with the tip down.
2. Using the heat cure oven assembly, cure the
assembly for 1 hour at 65°C [149°F].

1. Choose a flat end finish or physical contact (PC)

NOTE
NOTE
1. Carefully remove the protective sleeve from the
connector.
2. Firmly support the connector assembly.
3. Place the blade of the scribe tool directly above
the epoxy, and lightly draw the beveled edge across
the fiber parallel to the tip of the ferrule. See
Figure 7. After scoring the fiber, pull it straight away
from the connector.
Pull Fiber Straight Away

The flat end finish is recommended when the connector
might be exposed to a tough mechanical environment,
and the PC end finish is recommended for singlemode
connectors and will provide better performance by
reducing the optical power reflected back to the source.
2. For the flat end finish, place the white polishing
pad on the polishing plate. For the PC end finish,
place the green polishing pad on the polishing plate.
3. Place the 5-µm polishing film on top of the
polishing pad.
!
CAUTION
ALWAYS place the polishing bushing on a clean area of
the polishing film. NEVER start polishing on or across a
dirty section of the film.

4. Holding the polishing bushing, not the connector,
start polishing very lightly. Polish in an elongated
figure 8 pattern. See Figure 9. Initially a small
amount of exposed fiber will be worn away. This is
indicated by a narrow white trace on the film. As the
exposed fiber wears away, the trace will widen and
darken, indicating that epoxy is being removed. At
this point a moderate downward force may be
applied while polishing. Check the tip of the ferrule
often, and stop polishing on the 5-µm film when the
epoxy is light blue.
5. Clean the polishing bushing and connector
assembly with an alcohol fiber wipe.
