0.2-inch high or two Type 4R 0.4-inch high
reduced length splice trays (ordered separately).
2.4 The unit can be field connectorized using
Corning Cable Systems Buffer Tube Fan-out
(BTF) kits, which are ordered separately.
2.5 The EDC comes with brackets to mount
the unit to a wall or a standard utility pole. The
unit may be rack-mounted with an optional
rack-mount kit (purchased separately).
2.6 The unit may be pad-locked with a user-
supplied padlock after installation of the
provided quick-release latch kit.
2.7 Factory stubbed units are available with a
preconnectorized length of fiber optic cable
installed and strain-relieved inside the unit.
3. Precautions
3.1 Laser Handling Precautions
WARNING: Never look directly into the
end of a fiber that may be carrying laser light.
Laser light may be invisible and can damage your eyes.
Viewing it directly does not cause pain. The iris of the
eye will not close involuntarily as when viewing a
bright light. Consequently, serious damage to the
retina of the eye is possible. Should accidental eye
exposure to laser light be suspected, arrange for an eye
examination immediately.
WARNING: DO NOT use magnifiers in the
presence of laser radiation. Diffused laser light can
cause eye damage if focused with optical instruments.
Should accidental eye exposure be suspected, arrange
for an eye exam immediately.
3.2 Safety Precautions
CAUTION: The wearing of safety glasses to
protect the eyes from accidental injury is strongly
recommended when handling chemicals and cutting
fiber. Pieces of glass fiber are very sharp and can
damage the cornea easily.
CAUTION:The wearing of safety gloves to
protect hands from accidental injury is strongly
recommended when using sharp instruments.
CAUTION: Isopropyl alcohol is flammable
with a flashpoint at 50 ° F. It can cause irritation to
eyes on contact. In case of eye contact, flush eyes with
water for at least 15 minutes. Inhaling fumes may
induce mild narcosis. In case of ingestion, consult a
physician.
CAUTION: The filling compound remover
used to clean loose-tube cable contains petroleum
distillates which are harmful or fatal if swallowed.
DO NOT induce vomiting. Call physician
immediately.
3.3 Glass Fiber Precautions
WARNING: Cleaved glass fibers are very
sharp and can pierce the skin easily. Do not let cut
pieces of fiber stick to your clothing or drop in the work
area where they can cause injury later. Use tweezers to
pick up cut or broken pieces of the glass fibers and place
them on a loop of tape kept for that purpose alone.
Good housekeeping is very important.
3.4 Cable Handling Precautions
NOTE: Fiber optic cable is sensitive to excessive
pulling, bending and crushing forces. Consult the cable
specification sheet for the cable you are installing. Do
not bend cable more sharply than the minimum
recommended bend radius. Do not apply more
pulling force to the cable than specified. Do not
crush the cable or allow it to kink. Doing so may
cause damage that can alter the transmission
characteristics of the cable — the cable may have to be
replaced.
3.5 Installer Precautions
WARNING: Do not install this unit or work
with telephone wiring during a lightning storm.
Telephone lines can carry high voltages from lightning
causing electrical shock resulting in severe injury or
death.

9.2 Perform cable sheath removal steps per
instructions for the type of cable being
installed. Cut the cable to 2 meters (6 feet)
inside the unit.
NOTE: Do not expose the bare fiber until you are
ready to terminate it.
9.3 Install a sheath retention clamp onto the
cable sheath as illustrated in Figure 6. If an
armored cable is used, install the ground clamp
before installing the sheath retention clamp.
Ground kits are purchased separately.
9.4 Armored cable (metallic cable sheath)
should be grounded using a ground clamp
(Figure 7).
Figure 7

Page 6 SRP 003-304 • Issue 9 • July 2004
9.5 Secure the cable to the sheath retention
bracket using cable ties. Make sure the tabs on
the clamp material are in the recessed section
of the bracket (Figure 8).
9.6 When central member strain-relief is
required, the central member bolt must be
installed into the strain-relief bracket as shown
(Figure 9).
NOTE: Smaller diameter central members require
a shim to make sure they are adequately secured in
the central member clamp. Use a central member
clamp shim when necessary (Figure 10).
a) Remove the top nut and the two washers
from the bracket.
b) Loosen the remaining nut.
c) Insert the central member of the cable
between the bracket and the U-shaped
washer.
d) Arrange the buffer tubes to ensure
clearance around the central member
clamp assembly and hardware.
e) Tighten the hex nut.
f) Install the two flat washers.
g) Loosely install the other hex nut.
h) Wrap the strength member yarn in a
clockwise direction around the bolt and
between the flat washers.
i) Tighten the second hex nut.
j) Trim off the excess yarn and central
member.
NOTE: The exposed length of the central member
(after strain-relief) is to be less than or equal to 6.5
cm (2 1/2inch) between the U-shaped washer and
the end of the cable sheath.

Buffer Tube
Pigtail
a) Use a clean tissue soaked in alcohol to
gently clean the connector. Do not press
heavily on it as you clean.
b) Dry the connector prior to installation with
compressed air or a dry tissue.
c) Clean all areas that will contact the
connector adapter.
d) Do not force the connector into the
receptacle. If the connector does not fit
easily into the receptacle, back it out and
reinstall.
e) Install threaded connectors into the adapter
and tighten. Do not OVERTIGHTEN. Do
not allow the connector body (ferrule) to
turn as you screw it into place. This causes
the surfaces to grind against each other.
10.5 Remove the blank panels from the unit.
Install the connector panels into the connector
support bracket (Figure 14).
10. Connector Panels
10.1 LANscape®connector panels (Figure 12)
are sold separately, typically with connector
adapters installed.
10.2 If fibers are not already connectorized,
install connectors onto the fibers using pigtail
splicing or direct connectorization per
manufacturer’s instructions. If installing BTF
kits, proceed to Section 12.
10.3 Panels can be ordered with a specific
length of preconnectorized pigtail cable
installed. Pigtails are fiber optic cables with
connectors on one end that are installed into
connector panels (Figure 13). The other end of
the pigtail is terminated in a splice tray.
Figure 12
Figure 13
10.4 Install connectors into the appropriate
panels.
NOTE: The connector is a delicate device. Obey the
following precautions. Damage to the surface of the
connector will make it unusable: Figure 14

11. Splicing
11.1 Work on one splice tray at a time. Follow
the instructions provided with the splice trays.
a) Position the splice tray in the location it will
be secured to the holder.
b) Route two complete loops of buffer tube(s)
in a counterclockwise direction around the
radius guides. The radius guides are
designed with three sections. Begin routing
from the back section and work your way
forward with each loop in a different
section.
c) Place the buffer tube(s) where they will lie
after installation and mark the cable where
it will enter the splice tray 2 cm (3/4inch)
past the corner of the tray (Figure 15). (This
is where the buffer tube will be removed.)
d) Loop the pigtail fiber from the connector
panel around the radius guides as shown in
Figure 16 and mark the jacket the same way
you did for the buffer tube(s). Remove the
cable jacket from the pigtail.
Figure 15
Figure 16
e) Refer to the instructions provided with the
splice trays to determine the appropriate
length of fiber required in the tray. Measure
from the first mark towards the end of the
cable and mark the cable. (This is the fiber
that will be routed inside the splice tray.)
f) Trim the excess buffer tube beyond the
second mark.
g) Remove the splice tray and the coiled buffer
tubes.
h) Strip the buffer tube from the fibers from
the mark you made in the previous step c).
Clean the fibers that will be inside the tray
according to the cable manufacturer’s
instructions.
11.2 Bring both pigtails and buffered fibers to a
convenient splicing area - one pair at a time.
Secure these fibers to the splice tray according
to the instruction supplied with the splice tray.
IMPORTANT: When securing 900
µ m fiber to
the splice tray, 1.5 inch of vinyl tape around the
sheath as protection for the 900
µ m fiber is
recommended. Feed a cable tie through the strain-
relief holes in the corner of the tray. Carefully
tighten the cable tie around the tape-wrapped
portion of the fibers to secure the fibers to the tray.
11.3 Splice fibers as described in instructions
for the splicing method you are using.

Page 9
SRP 003-304 • Issue 9 • July 2004
11.4 As you complete a splice, label the
connector end of the pigtail with its port
identifier. Record information appropriately on
the record label inside the front door
(Figure 17).
11.5 Repeat for all required splice trays.
NOTE: Accurate record keeping is imperative
for an organized installation.
11.6 Once all splicing is complete, route the
buffer tubes and pigtails around the radius
control guides as shown in Figure 18. Route the
buffer tubes as shown in order to maintain the
appropriate bend radius to the connector panel.
11.7 Secure the splice tray to the wall as shown
in Figure 18. Discard spacers as required for the
type of tray installed.
12. Installing BTF Kits
12.1 Fiber optic cable can be installed using
Corning Cable Systems BTF kits.
12.2 Route the buffer tubes twice around the
radius guides in a counterclockwise direction.
Mark the location of the mounting bracket on
the buffer tubes as shown in Figure 19 to
determine the length required.

Figure 18
Figure 19
12.3 Install fan-out assemblies and connectors
according to the instructions provided with the
BTF kits.
12.4 Route the buffer tubes around the radius
guides and secure the fan-outs to the fan-out
bracket as shown using a cable tie (Figure 20).
Figure 20

Page 10 SRP 003-304 • Issue 9 • July 2004
Figure 22
12.5 Route the fiber in the fan-out tubing
around the guides and plug connectors into the
connector panel (Figure 21). Refer to the
previous connector care instructions to avoid
damaging the connectors during installation.
12.6 Label the connector end of the pigtail
with its port identifier. Record information
appropriately on the record label inside the
front door.
NOTE: Accurate record keeping is imperative
for an organized installation.
13. Installing Drop Cables
13.1 The EDC is designed to accept up to six
drop cables. Feed the drop cable through the
fitting you installed on the right at the base of
the closure.
NOTE: Drop cable subunit lengths should be
approximately 130 cm (51 inches) in length in order
to provide two loops of fiber slack around the radius
guides.
13.2 If the drop cables do not include central
members, secure the cables to the bracket using
a loosely tightened cable tie. When central
member strain-relief is necessary, remove the
drop cable strain-relief bracket and secure the
cable to the bracket using a cable tie as shown
(Figure 22).
a) Install the 8-32x5/8 screw from the front
side of the strain-relief bracket through the
flat washer and U-shaped washer. Loosely
install the hex nut.
b) Insert the central member of the cable
between the flat washer and the U-shaped
washer (Figure 23).
c) From the front side of the strain-relief
bracket, wrap the strength member yarn in a
clockwise direction around the screw and
under the U-shaped washer (Figure 23).
d) Tighten the hex nut.
e) If the central member is metallic, place the
eye of a ground wire (#6 AWG, purchased
separately in appropriate length from any
electrical supply store) under the U-shaped
washer or under the flat washer.

looseness and tighten.
Moisture: Check the housing for accumulated
moisture and place moisture absorbent
packets as needed.
Fiber Bends: Check fiber optic cable to make
sure bends do not exceed the minimum bend
radius. Check cable for unnecessary strain.
Check cable entries and exits for crimping
or crushing.
Documentation: Check record label to make
sure it is clear and accurate.
15. Specifications
The unit weighs 4.3 kg (10 lb)
f) Trim off the excess yarn and central
member.
g) Reinstall the strain-relief bracket.
NOTE: The exposed length of the central member
(after strain-relief) is to be less than or equal to 6.5
cm (2 1/2inch) between the U-shaped washer and
