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. The admonishments — in the form of Dangers, Warnings,
and Cautions — must be followed at all times. 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. GENERAL
1.01 The ADC 7-Inch Fiber Distribution System (FDS) (Figure 1) provides the termination,
splicing, and storage requirements of a large fiber optic cable system. The splice module is compatible
with the 7-Inch FDS or it can be used with or as a replacement for the Lucent LGX splice modules.
1.02 The FDS is modular in design so that additional capacity and functions can be added as
the system requirements change. A 7-Inch FDS consists of these major components.
•FDS Frame
•FDS Splice Module
•FDS Connector Module (72 terminations)
•Accessories including vertical cable guides
2. FIBER DISTRIBUTION SYSTEM SPLICE MODULE
2.01 The splice module permits splicing outside plant (OSP) or intrafacility fiber cable (IFC)
fibers to each other or to pigtail assemblies. The module provides a protective enclosure for
mounting splices and for coiling the service loop required in the splicing process.
2.02 The splice module can be used as a direct replacement for the LGX splice module and
can be installed in the same frame.
3. FDS ACCESSORIES
3.01 Optional Interbay Management Panels (IMPs) are available for installation between
frames. The panels provide storage for patch cords between frames. Other accessories such as
connector adapters, connector retainers, blank panels, and outside plant and intrafacility fiber
cable clamp kits are available to complete the installation.
3.02 Optional vertical cable guides can be attached at each side of the chassis (see Figure 2),
unless the splice module is installed in an ADC equipment frame which includes guides. The
cable guides form a vertical pathway and provide protection and organization for patch cords.
Four vertical cable guide styles are available. Their use is determined by frame spacing and
whether they are used with the 7-Inch FDS or LGX frames. Choose one of the vertical cable
guides that match what is installed on the other FDS equipment in the rack:
•2-inch/2-finger design - Used with LGX modules only, when no rack spacing is used and
a retrofit IMP panel is installed.
•2-inch/2-finger design – Used with 7-Inch FDS modules when no rack spacing is used
and a retrofit IMP is installed.
•4-inch/7-finger design –Used with 7-inch FDS modules when no rack spacing is used and
an IMP is not installed, or when racks are spaced five inches apart and an IMP is used.
•Rear vertical cable guide – Used in a cross-connect application, to organize and route
fiber optic terminal (FOT) equipment patch cords to the rear of the module.

individual splices. See Table 1 for catalog numbers.

A. Chassis
4.02 The splice module chassis is constructed of heavy gauge aluminum and has a baked
powder paint finish. The module is compatible with the 7-inch FDS connector module. Cable
access holes at the left and right side of both modules provide IFC or OSP cable fiber access.
Fiber access holes in the top and bottom of both modules permit protected routing of pigtails to a
connector module mounted either above or below the splice module.
B. Front and Rear Covers
4.03 A transparent front cover, hinged at the bottom, protects the fibers and pigtails from
normal activity near the module. The circuit designation labels provided are to be attached to the
front of each splice drawer. Circuit identification can be written on labels and attached to the
designation cards. The front cover can be removed for convenience and protection during
installation or other activity. The metal rear cover is hinged at the bottom and is removable. The
removable cover provides access to the interior of the chassis for fiber activity.

C. Splice Drawers
4.04 The splice module contains up to six splice drawers. Each splice drawer can handle two
ADC splice trays. Each ADC splice tray can handle 12 Fusion, heat shrink, mechanical
(elastomeric), rotary, FibrLok, Qpak, AOFR clip, or Raychem splices using the appropriate splice
chips. The FST-F3DF-HS18 splice tray can handle 18 heat shrink splices. Individual catalog
numbers are shown in Table 1.
5. INSTALLATION
5.01 This section describes how to install the splice module in the 7-Inch FDS or LGX frame.
The sequence of procedures is as follows:
•Unpack and inspect
•Chassis installation
•Cable routing and termination
•Fiber storage and splicing
A. Unpack
5.02 Unpack and inspect the various components as follows:
1. Inspect the exterior of the shipping container(s) for evidence of rough handling that may
have damaged the components in the container.
2. Unpack each container while carefully checking the contents for damage.
3. If damage is detected or if parts are missing, file a claim with the commercial carrier and
notify ADC Customer Service. Save damaged cartons for inspection by the carrier.
4. Refer to the Customer Service section at the back of this instruction sheet for repair,
replacement, and warranty information.
5. Save all shipping containers for use if the equipment requires shipment at a future date.
B. Chassis Installation
5.03 This procedure describes how to install the standard 7-inch FDS splice module in either
an ADC supplied frame or an LGX frame.
1. Release the latch on the front cover and open it about 2 inches (5 cm).
2. Lift the front cover from the hinges and place it where it will not be scratched or damaged.
3. The splice module brackets are installed for a 19-inch equipment rack. If a 23-inch
equipment rack is being used, remove the brackets and install them with the short
bracket side against the splice module side as shown in Figure 4.
Note: If a vertical cable guide is installed on the frame, it must be removed before
installing the splice module.

4. If applicable, remove the vertical cable guide from each side of the frame position in
which the splice module is being installed.
5. Place the splice module in its assigned position in the frame.
6. Insert two #12-24 screws supplied through the mounting bracket at each side of the
chassis and in the frame as shown in Figure 4.
7. Install optional vertical cable guides or reinstall the removed guides (see Figure 5).
8. Re-attach the front cover.

C. Cable Routing
5.04 Cable installation is performed from the rear side of the splice module. The OSP or IFC
cables are routed to the back of the module chassis from either above or below the module. The
pigtails are routed to the connector module through the fiber access holes in the top and bottom
of the chassis.
5.05 Prior to splicing, all cables (OSP and IFC) are routed to and secured to the side of the splice
module using a cable clamp kit. A total of eight cable clamp positions are available at both sides of
the chassis. To avoid congestion, OSP and IFC cables should be installed on opposite sides of the
module. Cables should be clamped as close as possible to the splice module to which the fibers will
be routed to reduce the length of cable sheath that needs to be stripped and cleaned.

Danger: Infrared radiation is invisible and can seriously damage the retina of the eye.
Do not look into the optical bulkhead of an operational transmitter, or into the launching
(output) end of an active fiber. A clean, protective cap or hood MUST be immediately
placed over any radiating bulkhead receptacle or optical fiber connector to avoid
exposure to potentially dangerous amounts of radiation. This practice also helps
prevent contamination of connectors and adapters.
5.06 Strip the outer sheath of the cable to expose the inner fiber bundles. Clean the cable core
as necessary per local practice. The cable sheath must extend about 0.75 inches (1.9 cm) beyond
the cable clamp. The service loop length shown in Figure 6 includes approximately 30 inches
(76.2 cm) of fiber within the splice tray for splicing. If buffer tubes or fiber protector sleeves are
needed add them at this time.
