Installing Pigtail Adapter Pack Assemblies and Splice Trays
This section describes how to install pigtail adapter pack assemblies and splice trays in an empty panel or as an addition in a termination/splice panel where some of the adapter pack positions were left vacant at installation. Either stranded or ribbon pigtails may be installed. The
3RU panel accepts up to six adapter packs pigtail assemblies. The 4RU panel accepts up to eight assemblies. The 5RU panel accepts up to 12 assemblies. Use the following procedure.
1. Install the pigtail adapter packs from the front side of the panel as described in
on Page 9 , threading through the pigtails to the rear side of the adapter bulkhead.
Note: As a rule of thumb, begin with the lowest number positions in the adapter bulkhead
(top right of bulkhead when viewed from the back of the panel) and route to the lowest splice tray in the stack; however, when splicing ribbon adapter packs, not all of the splice trays will be required and the lowest splice tray can be used for slack, if desired. Pigtails from the right side of the adapter bulkhead should be rounted around to the left in a
counterclockwise direction (as shown in Figure 25 ), pigtails from the left side of the adapter
bulkhead should be routed around to the right in a clockwise direction (
).
2. Route the pigtails within the panel, as shown. The routing is the same for stranded and ribbon except within the fanout holder, where there will be either a fanout chip for ribbon pigtail assemblies or a lacing tie down for stranded fibers.
Note: Route the 900 micron section of the pigtails around the inside radius until taken up fully then route the jacketed section two times around the outer radius limiters and into the
splice tray as shown in Figure 25 and

3. As the pigtail adapter packs are installed, route the fibers within the splice trays. The stranded fibers fill in 48 to a splice tray, The ribbon pigtails fill in 96 fibers per splice tray.
Note: Pigtails wound in a clockwise direction should enter the splice tray at the bottom
right as shown in Figure 27 for stranded pigtails and Figure 28 for ribbon pigtails. Pigtails
wound in a counterclockwise direction should enter the splice tray on bottom left (mirror image of routing shown in figures).
Note: When mass fusion splice chips are used, bottom splice tray can be used for slack.

Routing an IFC/OSP Cable
Allow a fiber service loop of at least 126-inches (3.5 meters) when stripping the cable sheath.
This provides sufficient length for routing the buffer tubes within the panel and for splicing.
After entry, the buffer tubes are routed to the splice tray. Use the following procedure.
1. Route the IFC/OSP cable to the selected entry opening at the side of the panel.
Note: Cables may enter the panel from either the top or bottom and may be clamped to either the left or right side.
show cable clamp position and cable
routing to splice tray for top left side entry. Figure 33 and
show top right entry.
Bottom entries are the same except cable clamp location is the same as shown in Figure 13 on Page 14
.
2. Strip back OSP cable buffer tube approximately 66-inches (167.64 cm) to expose optical fibers. Follow cable manufacturer's recommendations when stripping the sheath.
3. Break out the OSP cable corresponding to the dimensions given in Figure 30
. Follow cable manufacturer's recommendations when stripping the sheath.

4. Determine the correct clamp and grommet combination required to secure the cable to the panel. For details on the cable clamp itself, refer to
.
5. If splicing is to be completed later coil the buffer tubes around the radius limiters on the bottom of the panel and close rear cover. If splicing at the present time, follow local practice to complete the splices. Route the IFC/OSP fibers within the splice tray as shown in
for stranded fiber and Figure 36 for ribbon fiber.
Note: All subunits should enter the splice tray on the same side as the pigtails already present in the same splice tray.

Performing a Ribbon Fiber Heat Fusion Splice
Note: In this procedure, the splice trays and splice chips are assumed to have been loaded as described in the previous sections of these installation instructions.
Use the following procedure to perform a splice.
1. Unwind the splice tray from the panel and set it on an adjacent flat surface.
2. Remove the splice tray cover.
3. Unwind the splice chip from the splice tray to the full extent of the fibers, and set the splice chip on an adjacent flat surface.
4. Ensure that the bare fiber lengths of the distribution and feeder fibers are as shown in
Figure 37 (distribution fiber on top) or Figure 38 (feeder fiber on top). Note that the
lengths are different for the distribution and feeder fibers.
5. Perform the splice per local guidelines.
6. For the configuration being used, wind the splice chip back into the splice tray as shown in
.
7. Replace the splice tray cover.
8. If there is an additional splice tray with a splice to be performed, set the first splice tray to the side and repeat the above steps for the additional splice tray.
9. When done with all splice trays, wind the splice trays back into the panel so that they wind up stacked in the same order as at the beginning of this procedure.
