D. Fiber Storage

5.11Open the rear door about 2 inches (5 cm) and lift it from its hinges. Place the cover where it will not be scratched or damaged.

5.12Route OSP/IFC fibers through a side access opening in the chassis to the assigned drawer of the splice module. Service loop should be stored in the assigned drawer per Figure 8. Make sure to route fibers through the retaining ring in the back of the drawer. Passing the fibers through the retaining ring is required for the first pass only. The fiber bundles (service loop) should make three and one-half passes around the radius limiters and then be routed such that the end of the braided sleeve or protective sleeve occurs at a point between the two side radius limiters, noted as position “A ” in Figure 8, and just onto the splice tray. Coil the fiber bundles around the four radius limiters, either counter-clockwise if entering the splice drawer from the right, or clockwise if entering the splice drawer from the left.

E. Pigtails

5.13Individual fibers with a factory installed connector on one end should be bundled together in groups (usually 12) and protected by a braided sleeve or loose tubing, and routed from the FDS connector module to the splice module splice drawer through fiber pass-through holes at the top or bottom of the module, depending on the location of the FDS connector module.

5.14Because the pigtails and IFC/OSP fiber bundles must form a single service loop to enter the splice tray, both bundles must enter the splice module from the same side (either left or right side).
