1.4 Installation Process
The FDT2108D supports the LC/APC, LC/UPC, SC/APC, and SC/UPC adapters. The capacity of
LC is twice the capacity of SC. The method of installing LC is the same as the methods of installing
SC.
This document uses SC/APC as an example to describe the adapter installation method.
1. Put away materials that are not used during the installation for future use.
2. Put away components that are removed during the installation and protect them against
contamination.
3. Clean the required parts or components before the installation.

2 Installing the Cabinet
FDT2108D-288 and FDT2108D-576 can be installed only on the ground.
Building a Concrete Base
The FDT2108D-288 and FDT2108D-576 can be installed on the ground in the same way
except that they differ in the dimensions of the cabinet bases and the concrete bases. Specific
dimensional differences will be described in the following.
Step 1 Determine the dimensions of a concrete pedestal based on a marking-off template.

The FDT2108D-576 cannot be installed against the wall because it is operated from both the
front and the back. Furthermore, enough space must be reserved for installation.
Step 2 Plan the ground size required by the concrete base.
Ensure that the thickness (T) of the manhole (or handhole) concreted with the base complies with the
local construction standard.
If a local construction standard is not available, refer to China's standard: T = 200 mm (for large or
medium manholes); T = 150 mm (for small manholes); T = 75 mm (for handholes).
There are no special requirements on the height (H), width (W), or depth (D) of the manhole (or
handhole).
Step 3 a) Plan the dimensions of the concrete base, and build the base. b) Determine the installation
positions using the marking-off template, drill Φ16 mm holes at the planned positions using a
hammer drill, and install expansion bolts.

When using the marking-off template to determine the positions of installation holes, ensure that the
template is placed at the center of the concrete base, and the edges of the template are parallel with
those of the concrete base.

Installing the Cabinet
Step 1 Unlock and open the cabinet door, secure the door using a gag lever post, and remove the
screws that are used to secure the bottom panel, and lift the bottom panel.
The bottom panel of the cabinet is heavy. When removing it, exercise caution to avoid injuries
to installation personnel and damage to properties on the ground.
For the FDT2108D-576, the bottom panels of both the front and back cabinet bodies need to be
removed.
Step 2 Remove the side panels of the cabinet base. (For the FDT2108D-576, skip this step.)

Step 3 Secure the cabinet.
1. Remove the dustproof blocks from the top of the cabinet, and install hoisting ears.
2. Hoist the cabinet and place the cabinet on the concrete base with four installation holes
on the cabinet base aligned with the four anchor bolts (M12) on the concrete base.
3. Tighten the hex nuts using a socket wrench.
Step 4 Remove the hoisting ears, and install the dustproof blocks back on the top of the cabinet.
Step 5 Install the bottom panel back.
To install the bottom panel back, perform the installation in reverse of the removal procedure.

Securing Optical Cables
5.1 Front View and Rear View
Optical cables are routed from and spliced in the front of FDT2108D-576. On the top of the
chassis, the letter Aindicates the front view and the letter Bindicates the rear view.
5.2 Connecting Ground Cables
Punch a hole in the ground cable aperture and lead the ground cable on the cabinet and that on
the optical cable entry unit out from the left aperture.
The customer is responsible for leading the ground cable out to the protection ground.

5.3 Leading in Optical Cables
Step 1 Unlock and open the cabinet door. Then, secure the door using a spacer lever.
Step 2 Determine the position and sequence for leading in optical cables.
Bundle and ribbon optical cables can be led into or out of the cabinet through cable apertures.
This document uses default configuration of the optical cable entry unit as an example. Actual
configuration should be performed based on the delivered unit.
Step 3 Remove the baffle plate and lead in optical cables.

5.4 Coiling Straight-through Cables
5.5 Stripping Optical Cables
The length to be stripped from each optical cable is equal to 1.2 meters plus the distance from
the fixing position of the optical cable to the splicing tray, splicing and termination tray, or
direct splicing tray (1.2 m + L for short). Reserve optical fibers of a certain length to prevent
fiber breakage.
5.6 Securing Optical Cables
Securing Bundle Optical Cables Using Hose Clamps
Step 1 Lead the optical cable through the hose clamp, insert the strength member into the hole on the
fixing post, and secure the strength member and hose clamp.

If the strength member is too long and contacts the partition plate on the top of the optical
cable entry unit, voltage breakdown may occur when there are lightning strikes. It is
recommended that the strength member be inserted into the hole on the fixing post and then
be bent.
Step 2 Lead the optical cable into the integrated splicing and termination module from the right side
of the optical cable entry unit, and bind the optical cable at a proper position as required.
