2.3 Cross-Connecting Network Elements
In a variation of “Interconnecting Network Elements,” NE1s and NE2s are connected to the rear
of two LCX Fiber Patch Panels with the fronts reserved for patch cords to cross-connect the two.
Figure 27 shows a stylized version of this application.
2.4 Cross-Connecting Combinations
LCX Fiber Splice and Patch Panels can be used in combination to cross-connect IFC to
network elements.
Figure 28 shows a 48-fiber LCX Combination Panel (a 48-fiber LCX Splice Panel bolted to a 48-
fiber LCX Patch Panel). After the incoming IFC is spliced, the fiber strands are passed through
the 1-½ in. (38.1-mm) diameter hole in the top of the splice shelf to the patch shelf. Notice that
flexible edge protectors are used to protect the unsheathed fiber strand passing through holes to
an upper panel.
NOTE:
If you create your own combination LCX Splice and Patch Panel on site, remember to
remove the knockout plugs at the top and bottom of LCX panels before installing panels in racks.
(You can remove knockouts and install flexible edge protectors around edge of the holes after
you rack the panels; however, it is easier to do before you rack the panels.) Avoid removing the
knockouts on the top of the top-most and bottom of the bottom-most LCX panels. The knockout
plugs also provide fire abatement.
