Figure 7
Figure 7 displays the internal components and their connections, including optical interfaces
which come from the left-end while the right-end are the DAS connections.
Figure 8 is a typical internal configuration of a Plug-in. As depicted, uplink and downlink are
within the confines of the plug-in but shielded from each other.
Shown on the plug-in module block diagram’s right side are the rear plug-in connectors.
