General Safety Precautions
Warning – Wet conditions increase the potential for an electric shock when installing or
using electrically power equipment. To prevent shock, never install or use electrical equipment in a
wet location or during a lightning storm.
Danger – Do not look into the ends of any optical fiber. Exposure to laser radiation may
result. Do not assume the laser power is turned off or that the fiber is disconnected at the other end.
Caution – Always follow corporate safety practices when handing, striping and preparing
fiber optic cable, fiber shards can be dangerous if they are not disposed of properly. Always wear
proper safety equipment – including safety glasses, gloves etc. Refer to corporate standards when in
doubt.

5. FDH1 Cabinet
5.1. The Tii FDH1 Series Cabinet can be configured in three (3) versions including an all patch version, a
patch and splice version and a PON Version.
5.2. Figures 1 and 1a shows the general features of the FDH1.
5.3. The all patch version, shown in figures 1 & 1a, is equipped with LGX plates modular adapter plates (in
6, 8 or 12 adapters) for either24, 32 or 48 patch only configurations. This version assumes the use of
pre-stubbed drops with fan-out or field installable connectors on both input and output.
5.4. The unit also is equipped with 1 single LGX modular adapter plate for pass through fiber (where
applicable).
6. Patch and Splice
6.1. Shown in figure 2, is equipped with LGX plates modular adapter plates (in 6, 8 or 12 adapters) for
either24, 32 or 48 patch configurations and is equipped with up to four (4) splice trays.
6.2. One (1) to accommodate the feeder fiber and three (3) to accommodate splicing of the distribution
fibers.
6.3. Optionally the LGX adapters may be ordered with 6, 8 or 12 fiber pigtail assemblies, per-installed into
the spice trays. The pigtails may also be purchased separately.

7. PON Version.
7.1. Figure 4 shows the PON version which is a 1x 32 configuration with 1 X 12 fiber pass through and 4 x
8 LGX (32) modules distribution with an additional 4 X 8 LGX (32) modules for a parking lot. Included
is a 1 x 32 PON splitter.
7.2. Pigtails from the splitter are routed across the front of the inside door while the distribution fiber are
either splice in the splice trays and connected via factory installed pigtails to the modules or via field
installed mechanical connectors.

8.1. Depending upon configuration, the FDH 1 adapter plates will be labeled according to layout. Figure 5,
shows F – Designating 1-12 Feeder fibers, D – designating 1-32 Distribution fibers and PL- Designating
1-32 Splitter Parking Lot.
8.2. Figure 6 shows the standard door label for the recording of Feeder and distribution fiber (Subscriber
Termination Field).
8.3. The surface allows for field recording of the designated fiber and subscriber terminations.
