2. DESCRIPTION
(Refer to Figure 1)
Each simplex buffer connector kit consists of a
connector subassembly, a protective cover, and a
boot. Each duplex buffer connector kit consists of two
of each of these components and a duplex clip.
Each 1.6-- to 2.4--mm simplex jumper connector kit
consists of a connector subassembly, a protective
cover, a crimp eyelet/heat shrink assembly, and a
bend--limiting boot. Each duplex jumper connector kit
consists of two of each of these components and a
duplex clip.
Each 3.0--mm simplex jumper connector kit consists
of a connector subassembly, a protective cover, a
crimp eyelet, and a boot. Each duplex jumper
connector kit consists of two of each of these
components and a duplex clip.
These connector kits are used in telephone company
central offices, CATV head--ends, interbuilding
backbones, and customer premise applications.
The connectors accept 250--mm coated and 900--mm
buffered fiber and 1.6-- to 2.4--mm and 3.0--mm
jacketed fiber optic cable. With the use of the
field--installable duplex clip, all simplex connectors
can be joined into a duplex form. This instruction
sheet covers the termination, inspection, and
cleaning of these connectors.
Read these instructions thoroughly before starting
assembly.

3.2. Selection of Epoxy or Anaerobic Adhesive
Choose the epoxy or adhesive:
— The recommended epoxy is packaged in
pre--measured bags. It will cure between 115_ and
120_C [239_ and 257_F] in 30 minutes.
— The recommended anaerobic adhesive is
packaged in two bottles (adhesive and activator). It
will cure at 22_C [71.6_F] in approximately three
minutes.
3.3. Prepare the Cable
DANGER
TO AVOID PERSONAL INJURY, ALWAYS wear
eye protection when working with optical fibers.
NEVER look into the end of terminated or
unterminated fibers.
Laser radiation is invisible but can damage eye
tissue. Never eat, drink, or smoke when working
with fibers. This could lead to ingestion of glass
particles.
BE VERY CAREFUL to dispose of fiber ends
properly. The fibers create slivers that can easily
puncture the skin and cause irritation.

1. Slide the buffer boot (small diameter end first)
onto the fiber or buffer. See Figure 2.
2. Using the combination strip tool, strip the coated
or buffered fiber using the cable preparation
template (dimension is to scale) or use the
dimension given in Figure 3, exposing the glass
cladding.
3. Using the alcohol pad or lint--free cloth
dampened with alcohol, clean the glass cladding to
remove any coating residue.
CAUTION
NEVER clean the buffer or fiber with a dry cloth.
NOTE
408- 8675
For optimum results, the activator must be
applied properly and allowed to dry.

B. 1.6- to 2.4- mm and 3.0- mm Jacketed Cable
1. Slide the boot (small diameter end first) onto the
cable. Then slide the crimp eyelet/heat shrink
assembly (heat shrink end first) or crimp eyelet
onto the cable. Refer to Figure 2.
NOTE
If duplex cord is used, unzip the jacket into
separate cords at least 230 mm [9.0 in.] from the
end of the cable.

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
connector subassembly as shown in Figure 5.

3.4. Prepare and Apply the Epoxy or Adhesive
A. Preparation of Epoxy
1. Remove the separating clip from the bag of
epoxy and, using the epoxy mixer, mix the epoxy
inside the bag thoroughly for 2 minutes.
NOTE
When mixed properly, the epoxy should have a
uniform, translucent, amber color.

2. Using the epoxy applicator kit, install the needle
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.

3. Hold the connector subassembly in an upright
position, and insert the tip of the needle into the
rear body and support tube of the connector
subassembly until the tip of the needle touches the
base of the ferrule. Refer to Figure 6.
4. Keeping the tip of the needle against the base of
the ferrule,
slowly
inject the epoxy or adhesive into
the connector subassembly until a small bead of
epoxy or adhesive exits from the endface of the
ferrule. See Figure 6.
5. Withdraw the applicator slightly (approximately
1.0 mm [.04 in.]), hold for one second, then retract
the needle quickly
without
injecting any epoxy or
adhesive into the connector subassembly.
CAUTION
If too much epoxy or adhesive is injected, the
connector subassembly will not function properly.
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
