Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. These warnings are flagged by use of the triangular
alert icon (seen below) and are listed in descending order of severity of injury or damage and
likelihood of occurrence.
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.
1 DESCRIPTION
Note: The Fiber Panel Next Generation 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 1RU and 2RU panels can accommodate up to 48 and 96 terminations, respectively.
Typically, the panel ships empty. The panel may also be ordered 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 the 2RU panel.
Caution: Adapter packs and MPO cassettes should not be both used in the same panel.

The panel may be used in either singlemode or multimode applications, and with either stranded
or ribbon cable. Cables can be either Intrafacility Fiber (IFC) or Outside Plant (OSP). Figure 2
provides a cut-out view of a termination only 2RU panel. Figure 3 and Figure 4 show the
external features of termination/splice 1RU and 2RU panel, respectively.

The 1RU termination and splice panel has one splice tray. The 2 RU termination and splice
panel has two splice trays.
The panel can be installed on either a 19-inch or 23-inch rack WECO or EIA rack with a 2-, 5-,
or 8-inch recess. The panel is shipped with 23-inch mounting brackets installed in the 2-inch
recess position. An alternate 19-inch mounting bracket is provided.

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.
Additional procedures, after basic installation, are required for specific types of panels. For a
table summary of these procedures, see Table 1 on Page 10.
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.

2.1 Mounting Bracket Options
The 1RU and 2RU panels are shipped with mounting brackets installed for a 23-inch EIA/
WECO rack with a 2-inch recess. The mounting brackets can be reconfigured for a 5- or 8-inch
recess. A 19-rack mount with a 2-, 5-, or 8-inch recess is also possible. 19-inch mounting
brackets are provided. Figure 5 shows the available mounting options for both panels.

2.4 Panel Grounding
Each FPX fiber panel has a grounding location on each side of the panel marked by a standard
grounding symbol as indicated in Figure 9. Just below this location are four mounting holes for
securing a a two-hole lug such as shown in Figure 10.
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.
Note: Ground the unit to the local facility CBN (Common Bonding Network) or IBN
(Isolated Bonding Network) per local practice.
If installing an armored OSP cable, use the internal grounding stud (shown in Figure 9) to
ground the metallic sheath within the cable.

3PANEL-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.

The 1RU panel accommodates two adapter packs. The 2RU accommodates four adapter packs.
Adapter packs are installed in the same manner for both 1RU and 2RU panels. Adapter packs
installed on left side of panel are angled left while adapter packs installed on right side are
angled right.
Install the adapter packs as shown in Figure 11 (2RU shown).

3.4 Installing a Cable Clamp
Cables may enter the panel from the rear left or rear right side or both sides. Two cable clamps
are provided. Often only one cable clamp is used. Additional clamps can be ordered as
accessories. Use the following procedure to install a cable clamp.
1. Determine in the cable entrance location.
2. Refer to the appropriate procedure in this manual for routing cable to and within the panel.
3. Install the cable clamp as shown in Figure 15.

3.6 Preparing and Connecting a Pre-Connectorized Cable
This section tells how to prepare and connect a multi-fiber cable. The cable being installed must
conform to the breakout dimensions provided.
Use the following procedure.
1. If the cable is being connectorized:
a. Refer to Table 2 for breakout dimensions for variables L2 to L5.
b. Associate these variables to the breakout diagrams given in Figure 17 (IFC Stranded)
Figure 18 (IFC Ribbon), or Figure 19 (OSP) for the cable type being installed.
2. Determine the correct clamp and grommet combination required to secure the cable to the
panel. For details on the cable clamp itself, refer to Section 3.4 on Page 14.
3. Determine the cable entry location. Cables may enter the panel from either top or bottom
and may be clamped to either the left or right side.

as shown in Figure 20. For more information, refer to Figure 3.4 on Page 14.

3.7 Installing Pigtail Adapter Pack Assemblies and Splice Trays
This section describes how to install pigtail adapter pack assemblies and splice trays in an
empty panel or as an addition in a termination/splice panel where some of the adapter pack
positions were left vacant at installation.
The 1RU panel accepts up to two adapter packs pigtail assemblies. The 2RU panel accepts up to
four assemblies. Either stranded or ribbon pigtails may be installed. The illustrations in this
section show stranded pigtails.
Use the following procedure.
1. If splice trays are present in the panel, remove them and set them aside to be re-installed in
a subsequent step of this procedure.
2. Install the pigtail adapter packs as follows:
Note: “Left” and “right” directions here are as viewed from the rear of the panel.
Note: As a rule of thumb, begin with the lowest number positions in the adapter bulkhead
and route to the lowest splice tray in the stack; however, when splicing ribbon adapter
packs, not all of the splice trays will be required and the lowest splice tray can be used for
slack, if desired.
Pigtails from the right side of the adapter bulkhead should be routed
around to the left in a counterclockwise direction, pigtails from the left side of the adapter
bulkhead should be routed around to the right in a clockwise direction.
