1. GENERAL

1.01The ADC 7-Inch Fiber Distribution System (FDS) (Figure 1) provides the termination, splicing, and storage requirements of a large fiber optic cable system. The splice module is compatible with the 7-Inch FDS or it can be used with or as a replacement for the Lucent LGX splice modules.

1.02The FDS is modular in design so that additional capacity and functions can be added as the system requirements change. A 7-Inch FDS consists of these major components.

FDS Frame

FDS Splice Module

FDS Connector Module (72 terminations)

Accessories including vertical cable guides

2. FIBER DISTRIBUTION SYSTEM SPLICE MODULE

2.01The splice module permits splicing outside plant (OSP) or intrafacility fiber cable (IFC) fibers to each other or to pigtail assemblies. The module provides a protective enclosure for mounting splices and for coiling the service loop required in the splicing process.

2.02The splice module can be used as a direct replacement for the LGX splice module and can be installed in the same frame.

3. FDS ACCESSORIES

3.01Optional Interbay Management Panels (IMPs) are available for installation between frames. The panels provide storage for patch cords between frames. Other accessories such as connector adapters, connector retainers, blank panels, and outside plant and intrafacility fiber cable clamp kits are available to complete the installation.

3.02Optional vertical cable guides can be attached at each side of the chassis (see Figure 2), unless the splice module is installed in an ADC equipment frame which includes guides. The cable guides form a vertical pathway and provide protection and organization for patch cords. Four vertical cable guide styles are available. Their use is determined by frame spacing and whether they are used with the 7-Inch FDS or LGX frames. Choose one of the vertical cable guides that match what is installed on the other FDS equipment in the rack:

2-inch/2-finger design - Used with LGX modules only, when no rack spacing is used and a retrofit IMP panel is installed.

2-inch/2-finger design – Used with 7-Inch FDS modules when no rack spacing is used and a retrofit IMP is installed.

4-inch/7-finger design – Used with 7-inch FDS modules when no rack spacing is used and an IMP is not installed, or when racks are spaced five inches apart and an IMP is used.

Rear vertical cable guide – Used in a cross-connect application, to organize and route fiber optic terminal (FOT) equipment patch cords to the rear of the module.
