This product (hereafter called the pedestal ) is referred to as a hybrid because it also provides a distribution point for copper circuits. Figure 1 shows the basic components of the pedestal. From top to bottom in the figure, they are as follows: Page 2

3 Pedestal Cover protects the enclosed components. The cover lifts off the base as shown, providing access to the mounting plate assembly. It has a latch that requires a 216 hex driver to be opened. When properly installed, the pedestal cover will prevent the entry of water into vertical interior areas when the pedestal is immersed in up to six feet of water such as due to a flood. PEDESTAL COVER DISTRIBUTION SIDE MOUNTING PLATE ASSEMBLY DROP SIDE BASE BASE COVER DROP COVER STAKE A Figure 1. Basic Components of 12-Inch Fiber Access Terminal Mounting Plate Assembly holds the cables, splicing components, and connectors housed in the pedestal. Operationally, it divides into two areas: Distribution Side provides a sheath opening and subunit storage location for an OSP distribution cable. A cable subunit is routed to a splice tray where the fibers are spliced to internal 2 mm cables. The internal 2 mm cables are routed through a hole in the mounting plate to the drop side of the mounting plate. Page 3

4 The distribution side also provides an interface for copper twisted pairs. This is a physical collocation to minimize the number of pedestal placements in the same location; there is no interaction between fiber circuits and copper circuits. The interface uses splice modules and a terminal block to provide test points and customer drops, as shown in Figure 2. Drop Side provides a drop off point for fiber circuits. Drop cables are installed by splicing to the factory-installed 2 mm cables in the splice tray mounted on the drop side of the mounting plate assembly. Connectors positioned in the signal flow between the drop side splice tray and the distribution side splice tray provide a test point to access fiber circuits in either direction, as shown in Figure 2. Base is the boxlike physical foundation that holds the mounting plate assembly. Base Cover can be removed from the distribution side of the pedestal to gain entry to the base on the distribution side of the mounting plate assembly. Drop Cable Cover can be removed from the base for drop cable placement. From the pedestal, the drop cables are routed underground to the customer premises. Stake provides a mooring to hold the pedestal in place. The stake is driven into the ground and the base is secured to the pedestal using the hardware provided. 2 PRODUCT FUNCTION The pedestal provides both fiber and copper test points and customer drops, as shown in Figure 2. Fiber test points are accessed using fiber connectors. Copper test points are accessed using the drop terminal block. Drops are routed underground to customer premises.

Route the pass through fibers in a circular bundle inside the splice tray and tape them down. 13. Cut the 250 micron fibers assigned for splicing, and splice them with the factory-installed 900 micron fibers. Follow local practice for preparing and performing splices. 14. Route the remaining subunits (those that were not routed into the splice tray) by wrapping them twice around the radius limiters as shown in Figure 10 on page 11. Secure the subunits to the vertical wall of the mounting plate using fiber clips (for ribbon cable) or cable ties (for stranded cable), as noted in Figure If required, install a grounding system (not provided) that meets all local electrical codes. Check local codes for grounding system installation, use of clamps, wire size, and other grounding requirements. Typically, #6 AWG copper wire is used for the grounding wire. If the grounding system includes a ground rod, install the rod within the pedestal base. Leave sufficient slack in the grounding wire to allow the wire to be routed into pedestal. Connect the grounding wire to the ground lug shown in Figure 8 on page Reassemble the pedestal components. Refer to Figure 4 on page 7. Page 12

13 7 INSTALLING THE COPPER INTERFACE The pedestal has a copper interface that can be used to provide test and service access for individual twisted pairs in a copper cable. To provide this interface, the copper cable is looped within the pedestal and severed to position copper splice modules between the two sides of the severed pairs, as shown in Figure 12. In addition, as also shown, one or more pairs may be spliced to an internal cable connected to the drop terminal block (customer-provided). Drop wires terminated at the termination block are routed out of the pedestal and underground to customer premises.

17 8 ADDING A FIBER CUSTOMER A fiber customer is added by installing a fiber optical drop cable between the pedestal and the customer premise. The drop cable is spliced to an internal 2 mm cable in the splice tray located on the drop side of the pedestal. To add a customer, use the following procedure: 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. 1. Route the drop cable to the pedestal. Remove the pedestal cover, shown in Figure 4 on page 7. Remove the drop cable cover, shown in Figure 16. DROP DROP COVER A Figure 16. Removing Drop Cable Cover Page 17

18 2. Strip off the outer jacketing of the drop cable and route it within the pedestal as shown in Figure Tie off drop cable subunit to the splice tray with lacing. Leave a minimum of 24.0 inches of fiber in splice tray. Route the fiber in the splice tray as shown in Figure Identify the factory-installed fiber assigned to the customer. Strip the outer jacket from the drop cable to expose the 250 micron fiber. Splice the drop cable fiber to the identified fiber. Follow local practice to prepare and perform the spice. 5. Reassemble the drop cable cover and pedestal cover, and tighten the security fasteners. For an exploded view, see Figure 4 on page 7.
