7.2 Attenuators
Attenuators 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. Optional attenuators are installed on tab side of the sliding
adapter packs. See
Figure 9 .
7.3 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 11 .
2. Route the cables into the tray as shown in Figure 12 , 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 13 .
Figure 11. 12-Position Termination and Splice Tray Breakout Dimensions
4. Carefully position the tray within the splice area as shown in Figure 14 . 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 14 ).
5. Use the kurly locks provided to bundle fibers together as needed. Place kurly locks at
locations indicated in Figure 15 .
6. Verify that the completed tray looks as shown (see Figure 15 ).
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 13 , using a one-inch section of
soft wall jacket per the breakout dimensions shown in Figure 11 .
