1.2 Functional Description
The FEP is a front access, termination, storage, and distribution device for fiber optic cable
systems. The FEP consists of a chassis with a slot-hinge door that is removable. This provides
access to two 12-Pack assemblies or two 12-position bulkhead plates and a splice drawer. The
interior of the chassis can accommodate two 12-Pack assemblies or two bulkhead plates and a
splice drawer. The splice drawer slides out to provide access to the splice tray.
Patch cord management is enhanced with the use of angled adapters in the 12-Pack assemblies
or bulkhead plates. This allows easy routing of patch cords out each side of the FEP. Patch
cords are mated with the adapter/receptacles as needed to interconnect OSP fibers to Fiber
Optic Terminals (FOT). Excess patch cord length must be stored at the FOT or at an
intermediate storage device.
The splice drawer protects the pigtail to the OSP cables fiber splices. The drawer can
accommodate two 12-splice trays or one 24-splice tray. A rubber strap holds the tray(s) in
place and also allows easy removal of the tray when performing splicing operations. The
splice drawer provides space for storing pigtails and buffer tubes.
The OSP cable can be routed into the FEP side access ports from above, below, front, or the
rear of the panel. The outside diameter range of the OSP cable is 0.40 to 0.84 inches (10.2 to
21.3 mm). Cable strain relief is provided by attaching a cable clamp and grommet
combination to the side of the FEP. Four unpainted screw holes are provided for securing the
clamp and ground wire to the chassis.
1.3 Physical Description
The FEP chassis is constructed of heavy gauge aluminum, painted putty white. A door is
provided to protect the fibers and also provides an area for designation labels. The FEP is
designed for installation in various OSP cabinets. It can be installed in 19.00 inch (48.3 cm) or
23.00 inch (58.4 cm) racks (EIA or WECO hole spacing), using reversible 19/23 inch
mounting brackets. Refer to Figure 1.
The two 12-Pack assemblies or bulkhead plates are mounted and secured in place with quarter
turn fasteners. They can easily be removed by releasing the fasteners, for access to the back of
the FEP. The cover plate on the 12-Pack assembly can be loosened and swings out, as shown
in Figure 3 rear view bottom, to provide rear access to connectors seven to twelve. Connectors
one to six can be accessed by loosening and removing the plate on the opposite side of the
assembly. Refer to Figure 2.
The 12-Pack assemblies or bulkhead plates are not shipped as part of the FEP, but may be
ordered separately. The 12-Pack assembly is ordered equipped with pigtails and the bulkhead
plate is ordered without pigtails.
1.4 Technical Description
Specifications for the FEP are provided in Table 1.

INSTALLATION
Warning: Never install telephone equipment in a wet location or during a lightning storm.
When installing or modifying telephone lines, disconnect lines at the network interface before
working with uninsulated lines or terminals to prevent electrical shock.
This section describes the procedures for installing the FEP. The installation sequence is as follows:
• Panel Installation
• Outside Plant Cable Installation
• 12-pack Assembly Installation
• Bulkhead Plate and Pigtail Installation
• Splicing
2.1 Panel Installation
The FEP requires a 5.25 u 19 or 23-inch (13.34 u 48.26 or 58.42 cm) rack space. Mount the
FEP in an OSP cabinet using the following procedure.
1. Determine the available rack space and attach the reversible mounting brackets.
2. Align the FEP mounting bracket holes with the mounting holes in the rack and secure
with #12 mounting screws.
2.2 Outside Plant Cable Installation
The Outside Plant (OSP) cables enter the FEP through access openings on either side of the
panel. A cable clamp bracket is provided for additional support if the cable is routed into the
panel from front or rear. Use Figure 2 and the following procedures to install the OSP cables.
1. Route the OSP cables to the clamping point on either side of the FEP.
2. Determine the length of cable required to route the fibers from the clamp point to the
cable splice point. Allow an additional 16 feet (5.1 m) for a service loop.
3. Strip the cable sheath to the length determined in step 2. Use the cable manufacturer’s
recommendations for stripping the sheath and cleaning of fibers.
4. If the OSP cable is filled with water blocking compound, the cable end must be sealed to
prevent leakage. Blocking kits for stranded and ribbon cable are available from ADC.
See the OSP Accessories catalog for a listing of available kits.
5. If the cable has a metallic inner sheath and strength members, termination kits are available
to properly terminate and secure the cable jacket, as required by local practice. See the OSP
Accessories catalog for a listing of available kits.
6. If stranded cable is used and does not have buffer tubes for protection of the fibers, the
use of a buffer tube kit is required (see the OSP Accessories catalog). Install the kit using
the instructions supplied with it.
7. After the applicable kits have been installed, attach the cable clamp mounting bracket.
Refer to Figure 2.
