General Safety Precautions

1 PRODUCT INTRODUCTION

This section introduces the Two-Rack Unit (2RU) Fiber Management Tray (FMT).

1.1 General Description

The Two-Rack Unit (2RU) Fiber Management Tray (FMT) is a rack-mount fiber optic panel

consisting of a basic chassis with a slide-out drawer and a drop-in plate (DIP) installed inside

the drawer to provide various functions such as cable termination. The basic chassis is the same

for all models of the 2RU FMT. The drop-in plate, which is installed in the factory, depends on

customer order. Figure 1 shows a 2RU FMT with a drop-in plate providing a micro-VAM

splitter function.

The 2RU FMT is available with the following rack-mount options:

• EIA or WECO, 19-inch (48.26 cm);

• EIA or WECO, 23-inch (58.42 cm);

• ETSI, 20.28 inch (51.51 cm);

• All rack-mount options (EIA, WECO, or ETSI) provide the following recess options: 2.2-

inch (5.59 cm), 5-inch (12.70 cm), 6-inch (15.24 cm), or 40 mm (1.6 inch).

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.

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.

Caution: Placing a load in excess of 12 pounds (5.4 kg) onto an open tray will result in

misalignment or damage to the tray.

1.2 Configurations and Components

The 2RU FMT is currently available in a variety of DIP configurations, with more being

developed based on customer requests. The configurations available as of this printing of this

manual are:

• Termination (FMT-GRT, universal entry);

• Termination (FMT-GN7, left entry for Intrafacility Fiber Cable);

• Micro-VAMs (FMT-GVM, universal entry);

• 48-position termination/splice (FMT-GTL, left side splice, right side termination).

• Bulk storage (FMT-GBS, universal entry).

For multifiber cable assemblies, FMTs with termination for IFC (left entry) is your best choice. If

you are installing patch cords terminated with adapters, universal entry is your best choice.

1.2.1 Termination (Universal Entry)

Figure 2 shows the main external features of the 64-position termination model (available with

up to 72-terminations.

The features shown include the following (going from bottom left clockwise):

•Slide Latches (2)—Hold tray closed. Sliding latches inward releases tray to be opened.

1.3 Attenuators

Attenuators (optional) decrease the optical power in a fiber by a specific or adjustable amount.

Once the desired level of attenuation is determined, fixed attenuators may be inserted in the

fiber optic line to deliver a precise output. In the 48-position termination/splice (FMT-GTL)

configuration and 72-position termination configuration (FMT-GN7), attenuators may be used

on either side of the sliding adapter packs. In the 72-position termination (FMT-GRT)

configuration, attenuators may only be used on the rear (back) side of sliding adapter packs.

5. Route the cable within the tray as shown in Figure 14. Note that there are different

routings for cables being terminated at the front and rear of the adapters packs.

6. Secure the cables on the side and rear of the tray as shown in Figure 13.

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

Note: Always clean and inspect connectors and adapters before mating them. For

guidelines, refer to the connector cleaning instructions, ADCP-90-159.
