Configuring the Reverse Path
Combined Reverse Path with Single Transmitter
With a Combined Reverse Path configuration, all reverse paths are combined and
passed to Rev1 Out. Rev2 Out is unused and is terminated with the plug-in modules.
The combined signals at Rev1 Out can be routed to TX 1. As shown in the diagram,
the node includes only one transmitter, so the reverse path plug-in (part number
4015162) is used to route the combined output at Rev1 Out directly to the TX 1
transmitter. The Segmented OIB also allows for future segmentation through
replacement of the reverse path plug-in and installation of a second optical
transmitter.
To Reorient or Replace the Reverse Path Plug-in
Complete the following steps to replace the reverse path plug-in.
1 Open the housing. Refer to
1 Open the housing. Refer to
To Open the Node Housing (on page 15).
2 Remove the amplifier module. Reverse the steps for installing the amplifier as
described in Installing the Amplifier Module (on page 33).
3 With the amplifier module inverted, remove the shielded cover plate from the
rectangular enclosure cast into the back of the module.
4 Locate the reverse path plug-in on the interface board.
