DESCRIPTION
4.05
2.01
The COYOTE ® Rack Mount Cabinets are
designed to protect and organize optical fiber
splices and connectors in the central office, equipment
room, CEV and building entrances.
2.02
Four sizes of cabinets are available to
accommodate from 6 to 288 fiber splices and
connectors, using the COYOTE Splicing System.
2.03
The Transition Assembly and Splice Tray(s) in
the rear splicing area are the same as used in
the COYOTE Closure. Each Splice Tray accommodates
24 splices per tray in this application.
Lay the buffer tubes or unitube into the
Transition Assembly. For unitube application,
skip to Step 4.11.
PLP TIP: The retaining tabs on top of the Transition
Assembly are removable to facilitate placement of
buffer tubes.
4.06
Mark the buffer tubes at the back wall centerline of the Transition Assembly as shown in
Figure 2. (Note that for cable entry into the right side
of the cabinet the buffer tubes are routed against the
front of the Transition Assembly and then around to the
back wall.)
2.04
The Mounting Brackets allow mounting the cabinets to either 19" (483 mm) or 23"
(584 mm) equipment racks or cabinets.
2.05
Adapter Modules are available with all standard
fiber optic connectors and are ordered sepa-
rately.
3.00
MOUNTING ON RACK
3.01
Attach the appropriate Mounting Bracket to
each side of the cabinet using the screws provided. Shorter brackets are included for mounting to a
19" (483 mm) equipment rack. The longer brackets are
used for mounting to a 23" (584 mm) equipment rack.
3.02
FIGURE 2A - MARK BUFFER TUBES FOR
RIGHT SIDE CABLE ENTRY
Mount the cabinet to the equipment rack at the
desired height with the screws provided.
PLP Tip: Cabinets have keyhole slots for wall
mounting.
4.00
PREPARATION AND ROUTING OF
FEEDER CABLE
4.01
Remove a minimum of 90" (2,286 mm) of
sheath from the cable, and clean cable
according to accepted company practices.
FIGURE 2B - MARK BUFFER TUBES FOR
LEFT SIDE CABLE ENTRY
4.02
Remove the rear cover from the cabinet by
tur ning the 1/4-tur n fasteners counter
clockwise.
4.03
Remove the Splice Tray Hold Down Strap from
the threaded posts, and remove the Splice
Tray(s) to expose the Transition Assembly.
4.04
Slit the grommet in the cable entry at the rear
of the cabinet on the side being used for cable
entry, and position the cable into the entry.
4.07
Starting with one of the buffer tubes, remove
the buffer tube up to the mark, and clean the
fibers per your accepted company practices.
4.08
Feed the fibers from this buffer tube into one
of the Transport Tubes provided with the cabinet. Insert the end of the buffer tube 1/2" (13 mm) into
the Transport Tube.
4.09

Repeat Steps 4.07 and 4.08 for the
remaining buffer tubes.

4.10
Using two of the tie wraps supplied with
the Splice Tray(s), secure the buffer tubes
and Transport Tubes to the back wall of the Transition
Assembly. (Figure 3) Proceed to Step 4.16.

FIGURE 3 - SECURE BUFFER TUBES &
TRANSPORT TUBES TO TRANSITION ASSEMBLY
4.11
Mark the unitube at a point 2" (51 mm) from
where it enters the Transition Assembly (for
either right or left side cable entry).
4.12
Secure the Transport Tubes to the back wall
of the Transition Assembly with two of the tie
wraps provided. Be sure that the fibers are not bent as
they enter the Transport Tubes. If necessary, use some
of the felt tape provided the secure the fibers to the
Transition Assembly.
4.16
Carefully coil the Transport Tubes and bare
fibers into the base of the Transition Assembly
until a later step in this procedure.
Remove the unitube and clean the fibers per
your accepted company practices. Make sure to
maintain the identity of each bundle of twelve fibers.
5.00
4.13
5.01
Secure the unitube to the Transition Assembly with the tie wraps provided. Use two sets
of the tie down holes in the side of the Transition
Assembly.
4.14
Feed each bundle of fibers into one of the
Transport Tubes provided with the cabinet so
that the end of the Transport Tubes will be located just
beyond the center-line of the back wall of the Transition
Assembly. (Figure 4)

PIGTAIL PREPARATION &
ROUTING
The following are the required pigtail lengths
for each COYOTE Axcess Solutions Rack
Mount Cabinet:
RDC3................3 meters
RDC6................3 meters
RDC12..............3 meters
RDC24..............3 meters
5.02
Select one of the Adapter Modules
(purchased separately) and install it in one of
the locations in the cabinet bulkhead. Push the locking
fasteners at the ends of the Coupler Plate to secure it
in place.

PLP TIP: For the RDC6 Cabinet, install the lower row
of Coupler Plates first.
5.03
Select six pigtails, clean the fiber connector,
and connect them to the rear side of the
Coupler Plate.
5.04
Route the pigtails along the Transition Assembly
toward the right side of the cabinet, while maintaining
a smooth bending radius behind the Adapter Modules.
(Figure 5)
5.07
Feed the group of six buffered fibers into the
end of one of the Pigtail Tube Assemblies
with the larger diameter tube section, until the pigtail
jackets are within the larger tube 3/8" to 1/2" (10 mm
to 13 mm). (Figure 7)
PLP TIP: Moisten the ends of the pigtail jackets to
ease insertion into the tube.
FIGURE 7 - INSERT PIGTAILS INTO PIGTAIL
TUBE ASSEMBLY
FIGURE 5 - ROUTE THE PIGTAILS
5.05
Mark the jacket of each of the pigtails at a
point about 2" (13 mm) beyond the bending
radius as shown in Figure 6.
5.08
Repeat Steps 5.05 through 5.07 for each
group of pigtails.
6.00
FIBER SPLICING AND ROUTING
6.01
Route the Transport Tubes with the feeder
cable fibers and the Pigtail Tube Assemblies
within the Transition Assembly so that they will exit
at the front left corner of the Transition Assembly.
(Figure 8)
FIGURE 6 - MARK PIGTAILS
5.06
Carefully remove the jacket on each pigtail
up to the mark. Number or color code the
connector strain relief and the 900 micron tight buffer
of each pigtail for fiber identification.
PLP TIP: PLP® has pigtails available with different
colored 900 micron tight buffer coatings to simplify fiber identification.

FIGURE 8 - ROUTE TRANSPORT & PIGTAIL
TUBES WITHIN TRANSITION ASSEMBLY
6.02
Use two tie wraps to gently secure the Pigtail
Assemblies to the back right side of the Transition Assembly as shown in Figure 8.
6.03
6.07
Secure the Pigtail Tubes and Transport
Tubes to the Splice Tray with the tie wraps.
(Figure 11)
Place a Splice Tray on the threaded studs
over the Transition Assembly.
PLP TIP: Install the tie wraps into the Splice Tray
tie down holes prior to installing the Splice Tray.
(Figure 9)
FIGURE 11 - SECURE TUBES TO SPLICE TRAY
6.08
Route the Pigtail and Feeder Cable fibers one
complete turn around the Splice Tray and into
the splice groove furthest from the entry point of the
tubes. (Figure 12)
FIGURE 9 - INSTALL TIE WRAPS INTO
SPLICE TRAY
PLP TIP: Temporarily remove the retaining tabs from
the Splice Tray to ease fiber placement.
6.04
Select four Pigtail Assembly Tubes (use three
if working with the RDC3) and two Transport
Tubes for installation onto the Splice Tray.
6.05
Lay the Pigtail Assembly Tubes within the wide
entry slot of the Splice Trays and the Transport Tubes within the first two narrow slots, and mark
the tubes slightly beyond the tie down locations.
(Figure 10)
FIGURE 12 - ROUTE FIBERS WITHIN SPLICE
TRAY
6.09
Splice Feeder Cable fibers to Pigtail fibers
per accepted company practices. Place each
splice in a groove, starting from the furthest groove from
the tube entry.
FIGURE 10 - MARK TUBES IN SPLICE TRAY
6.06
Carefully cut the tubes at the marks, and
remove the excess length.
