6 DISTRIBUTION CABLE INSTALLATION AND SPLICING

This section describes how to install the OSP distribution cables in the ACE-142S/142V cabinet and how to use the distribution cable splice trays. If the cabinet is equipped with pre-installed distribution cables, refer to Section 6.2 for the bottom cover installation procedure.

6.1Distribution Cable Installation

The OSP distribution cables enter the ACE-142S/142V cabinet from the bottom. At the entry/ exit point to the cabinet, each distribution cable is secured with a clamp. Beyond the clamp, the outer sheath of the cable is removed to expose the optical fibers. Moisture blocking, grounding, and fanout kits must be installed (as required by local practice) to protect the exposed optical fibers. The OSP distribution cable fiber count may be any multiple of 72 (depending on the number of connector panels) with stranded or ribbon type fiber construction. From the clamping point, the optical fibers are routed to the splice trays for splicing to the connector panel pigtails.

Use the following procedure to install the distribution cable:

1.Route the OSP distribution cable into the cabinet from the bottom. If the cabinet is mounted on a concrete pad, use the duct on the left side.

2.Pull the cable up through the cabinet and strip off 156 inches (396 cm) of the outside cable sheath to expose the fiber subunits.

3.Install moisture-blocking, fanout, and grounding kits as required by local practice. Follow the installation instructions provided with each kit.

Caution: A fanout kit is required when installing ribbon cable. The fanout kit includes plastic tubes that protect the fiber ribbons and prevent damage.

4.Nine cable clamping positions are provided near the center of the cabinet as shown in Figure 20. Select one of the clamping positions as the attachment point for the cable.

Note: Use the middle cable clamp positions first and the top clamp positions second when installing the distribution cables. The bottom clamp positions are extra. The bracket for the top row of clamps may be removed if necessary to facilitate cable installation.
