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. 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 connector and adapter .

3 ROUTING AND SECURING CABLES

The following example shows typical cable routing. For simplicity, this figure shows IFC stranded fiber entering the panel from the left and ribbon fiber entering the panel from the right. Use the following guidelines for routing and installing the cables or patch cords:

Note: The following instructions apply to the left or right side of the FMT.

1. Open the tray fully, the lock open latch will lock the tray in the open position.

2. Route the cables to the FMT through the sliding radius limiter (A), around the rear radius limiter (B),

and secure to the tie-down lance (C).

3. Secure the cable on the rack using a cable clamp.

Note: Install the cable clamp kit following the instructions provided in the installation kit.

4. Adjust the cable position with the cable clamp as required to remove excess slack.

The FMT may be configured to provide the following functions:

-Termination and Splice, Universal Entrance

-Termination and Storage, Universal Entrance

For cable routing details and instructions on installing a vertical cable guide (optional), See below.
