A. Functional Description

1.02The FTD1 36-Fiber Wall Box (Figure 1) is designed to provide a wall-mounted, or rack- mounted, secure, fiber cable terminal for use in small to medium-sized fiber networks and customer premises applications. The wall box can accommodate up to four OSP cables and contains provisions for splicing and terminating 36 singlemode fiber circuits.

1.03The area behind the left front cover of the wall box houses three four-meter, 12-fiber, soft wall bundle fiber cables. The connectorized ends of these cables are terminated to fiber optic adapters in angled retainers on the bulkhead between the two sections of the wall box. The service loops of these cables are stored on four radius limiters, and the stub ends of the cable fibers are spliced to Outside Plant (OSP) cable fibers in heat shrink fusion splice chips in three splice trays. Up to four OSP cables can enter from either above or below the wall box (i.e., two from above and two from below). A Hubbell connector kit and four cable clamps are supplied with the wall box — enough to secure one OSP cable to the wall box and provide strain relief for four OSP cables. A rubber grommet is provided (unattached) for use as a dust cover at whichever corner (top or bottom) is not used for cable entrance.

1.04The area behind the right front cover of the wall box is used for terminating 3mm singlemode patch cords to the adapters. The patch cords can enter from either above or below the wall box. A rubber grommet is used as a dust cover at the panel opening that is not used for patch cord entry.

B. Physical Description

1.05The wall box is 19 inches (48.26 cm) wide, 10 inches (25.4 cm) high, and 4.76 inches (12.1 cm) deep, and is constructed of heavy gauge aluminum, painted putty white. Both hinged front covers are equipped with pull handles and key locks. Some of the physical features of the wall box are pointed out in Figure 2.
