tip onto the epoxy applicator. Make sure that the tip
is secure. Remove the plunger.
3.Cut the epoxy bag diagonally at one corner.
Squeeze the epoxy into the back of the applicator.
Re--assemble the plunger. Loosen, but do not
remove, the cap. Hold the applicator vertically (with
needle tip upward), and slowly push the plunger
until the entrapped air escapes and a bead of
epoxy appears at the tip. Remove the cap.
4. Using the alcohol pad or alcohol--dampened
lint--free cloth, clean the tip of the applicator
needle.
B. Preparation of Adhesive
1. Install the needles onto the two applicators,
making sure they are secure.
2. Remove the plunger from one of the applicators,
and load the adhesive into the back of the plunger.
Re--install the plunger.
3. Holding the applicator vertically (with needle tip
upward), allow the adhesive to drain away from the
needle then slowly push the air out of the
applicator until a bead of adhesive appears at the
tip of the needle.
4. Using the second applicator for the activator.
With the plunger fully forward, draw a small
amount (approximately 3 to 5 ml [.101--.169 oz]) of
activator into the applicator.
3.5. Apply the Epoxy or Adhesive
1. Remove the protective cover from the connector
subassembly.
2. If using epoxy, install the fiber protector onto the

3.7. Cure the Epoxy
A. Epoxy
1. Remove any excess epoxy from the connector
subassembly.
Excess epoxy must be removed BEFORE
CURING; otherwise, excess epoxy will be difficult
to remove after curing.
2. Place the connector subassembly (with attached
cure protector) in the heat cure oven according to
the instructions packaged with the oven. Refer to
Figure 11. Cure the epoxy between 115_and
120_C [239_and 257_F] for a minimum of
15 minutes.
This step will also shrink the crimp eyelet/heat
shrink assembly (of the jumper connector kit).
To avoid damage to the assembly, DO NOT
expose assembly to excessive temperatures.
3. After curing, grasp the cable, and gently lift the
assembly out of the oven. The assembly will be
HOT—allow sufficient time for the assembly to cool
before proceeding.
To avoid damage to the assembly, the assembly
must be allowed to cool.
B. Adhesive
1. Using the applicator, dispense a drop of
activator over the bead of the adhesive on the
endface of the ferrule.
2. Allow the adhesive to cure at an ambient room
temperature of 22_C [71.6_F] for approximately
1to3minutes.
For optimum results, the adhesive must be
applied properly and allowed to cure.
3. Using the heat gun, evenly heat the heat shrink
of the crimp eyelet/heat shrink assembly until it
shrinks into place. DO NOT overheat.
Overheating can cause fiber bending, breakage,
or high insertion loss.
3.8. Cleave the Fiber
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.

1. If used, carefully rotate the fiber protector to
remove it from the connector subassembly.
2. Firmly support the connector assembly.
3. Place the blade of the scribe tool directly above
the epoxy or adhesive. DO NOT allow the blade to
make contact with the epoxy or adhesive. Refer to
Figure 12.
Allowing the blade to touch the epoxy or
adhesive could damage, chip, or crack the cutting
tip of the blade.
4. Lightly draw the beveled edge of the blade
across the fiber parallel to the tip of the ferrule.
After scoring the fiber, pull it straight away from the
ferrule. The fiber should shear cleanly at the
scribed point.
3.9. Install the Boot
Slide the boot over the cable until it is against the rear
body of the connector subassembly. See Figure 13.

3.10. Polish the Fiber
It is recommended polishing the fiber using a
polishing machine. Machine polishing produces the
best results. Polish the fiber according to the machine
manufacturer’s instructions.
If machine polishing is not possible, hand polish the
fiber according to the following:
For optimum results, keep the polishing films
clean.
1. Level the fiber. Using a small piece of the 5--mm
(light grey) polishing film, lightly polish the endface
of the ferrule in a small circular motion to remove
the fiber stub down to the level of the epoxy or
adhesive and until the fiber stops leaving a trace
on the film.
2. Install the connector subassembly onto the
polishing bushing.
3. Place the polishing pad on the polishing plate.
Place the 9--mm polishing film on the polishing pad.
ALWAYS place the polishing bushing on a clean
area of the polishing film. NEVER start polishing
across a dirty area of the polishing film.
4. Holding the polishing bushing and connector
subassembly, place the polishing bushing on the
film. Using light pressure on the ferrule, polish in
an elongated figure--8 pattern (approximately
50.8 mm [2.0 in.] long). Make 15 figure--8 patterns.
5. Clean the endface of the ferrule and the
polishing bushing with the alcohol pad or
alcohol--dampened lint--free cloth.
6. Remove the 9--mm polishing film from the
polishing pad, and place the fine diamond (green
or lavender) polishing film on the polishing pad.
Hold the assembly and, using very light pressure,
polish the tip of the fiber in an elongated figure--8
pattern (approximately 50.8 mm [2.0 in.] long).
Make six figure--8 patterns.
7. Inspect the fiber according to Paragraph 3.11.
If small peripheral chips are evident in the fiber,
continue polishing the fiber with the fine diamond
film. Inspect the fiber again. If the fiber is not
acceptable, it might be necessary to use the 9--mm
polishing film, then use the fine diamond polishing
film to remove small peripheral chips.
MAKE SURE to clean the endface of the ferrule
and the polishing bushing between film changes.

8. Clean the endface of the ferrule and the
polishing bushing with the alcohol pad or
alcohol--dampened lint--free cloth.
9. Remove the fine diamond polishing film from the
polishing pad, and replace it with the 0.3--mm
(white) polishing film.
10. Holding the polishing bushing and connector
subassembly, place the polishing bushing on the
film, and using light pressure on the ferrule, polish
in an elongated figure--8 pattern (approximately
50.8 mm [2.0 in.] long) according to the following:
— for multimode connectors, make three figure--8
patterns
— for singlemode connectors, make 12 figure--8
patterns
11. Clean the endface of the ferrule and the
polishing bushing with the alcohol pad or
alcohol--dampened lint--free cloth.
3.11. Inspecting the Fiber
Before inspecting the fiber, DISCONNECT the
fiber from the power signal source. NEVER
inspect or look into the end of a fiber when
optical power is applied to the fiber. The infrared
light used, although it cannot be seen, can cause
injury to the eyes.
1. Using the microscope, inspect the endface of
the ferrule and fiber according to the following
criteria (refer to Figure 14):
— Make sure that all adhesive or epoxy is removed
from the ferrule. Use a sharp blade to remove
adhesive or epoxy from the chamfered edge of the
ferrule. DO NOT touch the fiber.
— Dirt may be mistaken for small pits. If dirt is
evident, clean with the alcohol pad or
alcohol--dampened lint--free cloth, then dry.
— Fine polishing lines are acceptable.
— Small peripheral chips at the outer rim of the
fiber are acceptable.
— Large chips in the center of the fiber are
unacceptable, and the fiber must be re--terminated.
2. If not installing the connector immediately, install
the protective cover onto connector subassembly
to prevent contamination to the endface of the
ferrule.
3.12. Install Connectors onto Duplex Clip
1. Identify Channel A of the connector and locate
Cavity A on the duplex clip.
To determine the polarity of a patchcord, light one
fiber path. One of the two connectors should be
illuminated. Designate the lit channel as Channel
A and the other channel as Channel B.
2. Center the rear body of the connector
subassembly between the cavity of the duplex clip
as shown in Figure 15, Detail A, and using a
biasing force, insert the connector into the cavity.
Correct placement is denoted by an audible “click.”

4. CLEANING PROCEDURE
4.1. Connector
To avoid personal injury, compressed air used for
cleaning must be reduced to less than 207 kPa
[30 psi], and effective chip guarding and personal
protective equipment (including eye protection)
must be used.
1. Wipe completely around the ferrule with an
alcohol pad or lint--free cloth dampened with
isopropyl alcohol. Then wipe completely around the
ferrule using a dry lint--free cloth.
2. Place the dry lint--free cloth on a smooth, flat
surface. Holding the connector perpendicular with
the surface, wipe the endface of the ferrule across
the cloth.
3. Blow compressed air across the endface of the
ferrule.
4. Using the microscope, examine the endface of
the ferrule for debris. If debris is present, repeat
Steps 1 through 3.
This is the final step prior to connector
installation. DO NOT wipe the ferrule or allow it
to touch anything before mating the connector.
5. Mate the connector to the receptacle. If the
attenuation is too high, unmate both connectors (if
applicable), repeat Steps 1 through 4, and clean
the receptacle according to Paragraph 5.2.
4.2. Receptacle
1. Blow compressed air through the receptacle.
If both connectors are not mated, blow
compressed air into the open end of the
receptacle.
