and are listed in descending order of severity of injury or damage and likelihood of occurrence.
.
GENERAL SAFETY PRECAUTIONS
1 PRODUCT DESCRIPTION
The CommScope Fiber Management Tray (FMT) is a rack-mount, front-access fiber optic tray
available in a variety configurations. Some of these are noted below:
• 12- or 16-position termination and storage (universal storage);
• 24-position termination and storage (left or right storage);
• 12-position termination and splice (left or right splice entry);
• 32-, 48-, or 60-cable bulk slack storage (capacity dependent on cable diameter).
Rack-mount and recess options include:
• EIA or WECO, reversible 19- or 23-inch (48.26 or 58.42 cm) mounting brackets installed
for 5-inch recess;
• ETSI, 20.28-inch (51.5 cm) with 40 mm recess.
Customer adjustable recess configurations include:
• EIA 19-inch (48.26 cm) with 40 mm recess;
• EIA or WECO, 19 or 23-inch (48.26 or 58.42 cm) FMT offer
2.2-inch (5.59 cm), 3.1-inch
(7.9 cm), 5-inch (12.7 cm), or 6.5-inch (16.5 cm) recess;
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.
Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter
packs. Exposure to invisible laser radiation may result. An optical power meter should be used to
verify active fibers. A protective cap or hood MUST be immediately placed over any radiating
adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation
exposure. This practice also prevents dirt particles from entering the adapter or connector
.

6 INSTALLING AND ROUTING CABLES
6.1 Routing and Securing Cables
The FMT may be configured to provide termination and storage, storage only, or termination
and splice functions. For each configuration, the fiber optic cables or patch cords are routed to
the FMT, installed within the sliding tray, and secured.
All cables enter the FMT through one of the two sliding entry points, located on the left and
right sides of the FMT. When properly installed, the slack loop that forms when the FMT is
closed is taken up within the FMT by movement of the sliding radius limiter.
Danger: I nfrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter
packs. Exposure to invisible laser radiation may result. An optical power meter should be used to
verify active fibers. A protective cap or hood MUST be immediately placed over any radiating
adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation
exposure. This practice also prevents dirt particles from entering the adapter or connector
.
Caution: Placing a load in excess of 5 pounds (2.3 kg) onto an open tray will result in
misalignment or damage to the tray.

Figure 7 and Figure 8 show typical cable routing. Prior to routing cables, review the installation
procedure corresponding to the configuration (provided in
Subsection 6.3 through Section 6.6 ).
Then use the following guidelines for routing and installing the cables or patch cords:
1. Open the tray fully, the lock open latch will lock the tray in the open position (see
Subsection 7.1).
2. Route the cables to the FMT. The cables may be routed from either overhead or under the
floor and to the left or right side of the FMT depending on configuration requirements.
3. Secure the cable on the rack using a cable clamp such as shown in
Figure 7 and Figure 8.
4. Route the cables into the FMT through the specified sliding radius limiter(s).
5. Route and connect the cables within the FMT as required by the configuration. Refer to
the installation procedure that corresponds to the FMT configuration.
6. Adjust the cables within the FMT until all excess slack is removed or stored.
7. Secure the cables to the back of the FMT at the rear tie-off point (see Figure 7 and Figure 8 ).
Note that a tie-off point is provided on both the left and right side.
8. Use the kurly locks provided to bundle fibers together between the sliding radius limiter
and the rear radius limiter as needed.
9. Adjust the cable position with the cable clamp as required to remove excess slack.
10. Release the lock open latch and close the tray (see Subsection 7.4).
Note: Install the cable clamp kit following the instructions provided in the installation
drawing shipped with the kit. Ribbon blocking kits are available from CommScope in a
variety of sizes to match any ribbon cable type.

6.6 12-Position Termination and Splice Tray
Termination and splice trays provide 12 termination and splice positions. Install the cables for a
12-position termination and splice tray as follows:
1. Break out the cable corresponding to the dimensions provided in Figure 15.
2. Route the cables into the tray as shown in Figure 16, and perform the splices outside the
tray at an adjacent work area, as shown. Perform the splices following local practice.
Refer to pigtail installation drawing (provided with FMT) for pigtail connection scheme.
3. Loop the cables three times around the radius limiters as shown in Figure 17.
Figure 15. 12-Position Termination and Splice Tray Breakout Dimensions
4. Carefully position the tray within the splice area as shown in Figure 18. Make certain that
the pre-terminated and customer fiber bundles are properly routed around the appropriate
radius limiters as they enter the FMT (see Figure 18).
5. Use the kurly locks provided to bundle fibers together as needed. Place kurly locks at
locations indicated in Figure 19.
6. Verify that the completed tray looks as shown (see Figure 19).
Note: Splicing instructions are not included. For splicing instructions, follow local practice.
Note: Tie off the cable at the tie off point shown in Figure 17, using a one-inch section of
soft wall jacket per the breakout dimensions shown in Figure 15.
