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
, threading through the pigtails to the rear side of the adapter bulkhead.
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: 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
), pigtails from the left side of the adapter
bulkhead should be routed around to the right in a clockwise direction (
).
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
