Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
Caution: Fiber optic cables may be damaged if bent or curved to a radius that is less than the
recommended minimum bend radius. Always observe the recommended bend radius limit when
installing fiber optic cables and patch cords.

1 DESCRIPTION
The 3, 4, & 5 RU FPX fiber panel, shown in Figure 1, can accommodate up to 144, 192, or 288
LC terminations, respectively (72, 96, and 144 per side, respectively). This panel may be ordered
empty or with adapter packs, Multifiber Push-On (MPO) cassettes, splice trays, or pigtails. The
panel can be configured for termination only (without splice trays) or for termination/splice.
Figure 1 shows a front view of the panel.

Danger: Exposure to laser radiation can seriously damage the retina of the eye. Do not look
into the ends of any optical fiber. Do not assume the laser power is turned-off or that the fiber is
disconnected at the other end.
Caution: Improper handling can damage fiber optic cables. Do not bend fiber optic cable more
sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not
apply more pulling force to the cable than specified. Do not compress the fiber or allow it to kink.
Note: The FPX panel is designed to be installed in an environmentally controlled network
telecommunications facility such as a Central Office, Controlled Environmental Vault, or
Data Center.

The FPX fiber panel can be ordered loaded with adapter packs only, or loaded with both adapter
packs and a pre-terminated, factory-installed cable. While not recommended, field-installed
connectors may be accommodated depending on boot length.
The panel can be used in either singlemode or multimode applications, and with either stranded
or ribbon cable. Cables can be either Intra Facility Fiber (IFC) or Outside Plant (OSP). Figure 2
shows a rear view of the panel in a pre-terminated configuration.
Termination/Splice panels have splice trays mounted inside the panel for easy access and cable
routing. The panel accommodates LC/SC adapter packs, MPO adapter packs, and MPO
cassettes. Radius limiters located inside the panel must be removed prior to panel installation
when using MPO cassettes.
When a panel is ordered loaded with adapters, a fanning tree such as shown in Figure 2 is
included. The fanning tree is used to support the fibers routed to the adapters.

2 BASIC INSTALLATION
Basic installation consists of procedures done for every type of FPX fiber panel, selecting the
mounting bracket location and reconfiguring the brackets if desired, installing the panel on an
equipment rack, installing the vertical cable guides, and grounding the panel. Instructions for
these procedures are provided below.
2.1 Mounting Bracket Options
The panel is shipped with mounting brackets configured for a 23-inch EIA/WECO rack with a
2-inch recess. The panel can be mounted with a 2, 5, or 8 -inch recess in 19 or 23-inch racks
using EIA or WECO mounting hole patterns. Figure 3 shows the available mounting options.
Figure 3. Mounting Options (5RU Panel Shown)
Warning: Never install equipment in a wet location or during a lightning storm. When
installing or modifying communication lines, disconnect lines at the network interface before
working with uninsulated lines or terminals.
Note: The FPX panel is designed to be installed in an environmentally controlled network
telecommunications facility such as a Central Office, Controlled Environmental Vault, or
Data Center.

2.3 Installing Vertical Cable Guides
Install the two Vertical Cable Guides (VCGs) on the panel as follows, referring to Figure 5:
1. Align the slotted mounting holes in the cable shield with the holes in the VCG mounting
bracket.
2. Align the holes in VCG with the holes in the cable shield and mounting bracket. Use 6-32
screws (2 per VCG, provided) to secure the VGC’s to panel.

2.4 Grounding the Panel
Each FPX fiber panel has a grounding location on each side of the panel marked by a standard
grounding symbol as indicated in Figure 6. Just below this location are four mounting holes for
securing a a two-hole lug such as shown in Figure 7. The lug may be mounted in either a
horizontal or vertical orientation. Secure the lug using the two #10-32 ground screws and two
#10 star washers provided. Route a a #6 copper grounding cable from the lug to office ground.
If installing an armored OSP cable, use the internal grounding stud (shown in Figure 6) to
ground the metallic sheath within the cable.

Note: Ground the unit to the local facility CBN (Common Bonding Network) or IBN
(Isolated Bonding Network) per local practice.

3 PANEL-SPECIFIC INSTALLATION PROCEDURES
For purposes of installation, the FPX fiber panel is divided into four types:
• Empty panel (includes rear management hardware to accept adapter packs, pigtails, and
splice trays);
• Termination panel loaded with adapters only (includes rear management hardware to
accept multi-fiber cable assemblies);
• Termination/splice panel: loaded with adapters, pigtails, and splice trays;
• Stubbed panel: completely equipped with a preterminated cable stub.
3.1 Panel Types and Procedures Done for Each Type
Table 1 lists the main panel types shipped to the customer and the installation procedures that may
be done for each type.
3.2 Installing Adapter Packs (LC, SC, or MPO)
This section describes how to install adapter packs (LC, SC, or MPO) in an empty FPX panel.
The 3RU panel accepts up to six adapter packs. The 4RU panel accepts up to eight adapter
packs. The 5RU panel accepts up to 12 adapter packs. Use the following procedure.
1. Orient the adapter pack as shown in Figure 8.
