Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. 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.
1DESCRIPTION
ADCP-92-098 • Rev C • May 2018
The FPX 1U and 2U Panels can accommodate up to 48 and 96 terminations, respectively. The
FPX 1U and 2U Panels can be configured for termination and splice or termination only
(without splice trays).
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.
Figure 1 shows the external features of a typical 1U panel.
Typically, these panels ship empty (without adapter packs, MPO cassettes, splice trays, or
pigtails), but they may also be ordered with any of these components already installed.The panel
accommodates adapter packs and MPO cassettes.
Caution: Adapter packs and MPO cassettes should not be both used in the same panel.
The panel may be ordered loaded with adapter packs only, or loaded with both adapter packs
and pre-terminated, factory-installed cable. While not recommended, field-installed connectors
can be accommodated.
The panel may be used in either single mode or multimode applications, and with either
stranded or ribbon cable. Cables can be either Intrafacility Fiber (IFC) or Outside Plant (OSP).

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.
2.1Selecting a Mounting Bracket Option
The 1U and 2U panels are shipped with mounting brackets configured for a 19-inch EIA/
WECO rack with a 5-inch recess. The mounting brackets can also be reconfigured for a 4-inch
rack recess.
Figure 4 shows the available mounting options for both panels.
The panel has a tray release button and tray retainer clips designed to ensure that the drawer is
opened carefully and remains open until work in the drawer is competed. These items look the
same and operate the same on the 1U and 2U panels.
Use the following procedure to slide the drawer in and out (2U shown):
1. To release a closed drawer, press the release button down, as shown in Figure 7, and slide
the drawer out to the first detent.
Each panel has a grounding location marked with the standard grounding symbol. This location
is on the right side of the panel (see
provided to attach a 2-hole lug terminal at the grounding location, as shown in Figure 11.
Follow local practice.
Note: Ground the unit to the local facility CBN (Common Bonding Network) or IBN
(Isolated Bonding Network) per local practice.

The 1U panel accommodates two adapter packs. The 2U accommodates four adapter packs.
Adapter packs are installed in the same manner for both 1U and 2U 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
The 1U panel accommodates two MPO cassettes, the 2U accommodates four. The procedure for
the 1U and 2U is the same. To install or remove an MPO cassette, pull the Nylatch plunger
fastener out, orienting the MPO as shown in
Caution: Adapter packs and MPO cassettes should not be both used in the same panel.

Install cable after panel is mounted in the equipment rack, as described in
Section 2.2
. Installation
consists of routing cable to the panel, stripping back outside cable sheath exposing the optical
fibers, installing a cable clamp to secure cable to the panel, and routing fibers to the splice tray. If
cable has a metallic strength member it must be grounded following local practices.
Two clamps are provided since two cables may be installed on a single panel. Each clamp can
accommodate one cable with an outside diameter of 0.2 to 0.7 inches (0.51 to 1.78 cm). Refer to
Section 3.1 for clamp installation. Typically, only one cable is installed per panel. the cable
clamp may be installed on either side.
Allow a fiber service loop of at least 96-inches (2.5 meters) when stripping the cable sheath. This
provides sufficient length for routing the buffer tubes within the panel and for splicing. After
entry, the buffer tubes are routed to the splice tray. Splice tray mounts on the bottom of the panel.
Use the following procedure to secure the IFC/OSP cable at the fiber entry point and to route the
optical fibers into the panel:
1. Route the IFC/OSP cable to the selected entry opening at the side of the panel.
Note: Cables may enter the panel from either the left or right and may be clamped to
either the left or right side. For cable mounting locations see
Figure 14.
Figure 14. Typical FPX Configured with Termination Only (Rear View)
2. Strip back cable sheath approximately 96-inches (2.5 meters) to expose optical fibers.
Follow cable manufacturer's recommendations when stripping the sheath.
3. Determine the correct clamp and grommet combination required to secure the cable to the
panel. A rubber clamp and grommets of various sizes are provided. Select a grommet that
when placed around the cable, has a gap of nearly zero to 0.30 inches (0.76 cm). If the

cable diameter is greater than 0.70 inches (1.78 cm), only the rubber clamp is required.
4. Use the rubber clamp, clamp cover, grommet (if required), and two screws to secure the cable
end to the side of the panel, as shown in
5. If splicing is to be completed later coil the buffer tubes around the radius limiters on the
bottom of the panel and close rear cover. If splicing now follow local practices.
3CABLE CLAMP INSTALLATION
3.1Installing a Cable Clamp for OSP Cable
For both termination and splice panels and termination only panels, an OSP cable must be
installed and routed. The procedure is the same regardless of the type of panel being installed.
The OSP cable can enter the panel from the left or right side of the panel (as viewed from the
rear of the panel). Determine the direction of cable entrance and install the cable clamp as
shown in the example in
Note: This procedure requires use of the MPO trunk cable clamp kit, which can be
ordered from CommScope using catalog # TFP-ACC002. This kit is required for routing
MPO trunk cable in panels with MPO adapter packs. This kit may also be used for routing
MPO trunk cable in panels with MPO cassettes, but the kit is not required for MPO
cassette applications.
Note: When the MPO trunk cable clamp kit is used, there are limitations on the number of
panels that can be stacked up on the rack in certain configurations. For more information,
refer to the instructions (ADCP-92-080) provided with the kit.
For panels with MPO adapter packs, an MPO trunk cable must be installed and routed. The
procedure is the same regardless of the type of panel being installed.
The MPO trunk cable can enter the panel from the left or right side of the panel (as viewed from
the rear of the panel).
Determine the direction of cable entrance and install the cable clamp. Some orientation
examples are shown in

4.1Termination and Splice Panel Procedures
4.1.1Routing Pigtails
Typically, the termination and splice panel is shipped without adapter packs or pigtails and will
therefore need to be configured as required. Alternatively, the panel may have been ordered with
adapter packs pre-cabled with pigtails or with MPO cassettes already installed. If pigtails need
to be routed in the panel being installed, route the pigtails corresponding to the example shown
in
Figure 17 for a right side adapter pack or Figure 18 for a left side adapter pack.
