Chapter 2 RFU-D-HP Overview
RFU-D-HP is a MultiCore RFU that provides high power for long-haul applications. Like RFU-D, RFU-D-HP incorporates
two modems, which are connected to the IDU via a single baseband interface.
RFU-D-HP offers a flexible and modular branching system that enables the combination of different bands for different
carriers. For example, the same link can be used for both L6 and U6 or 7 and 8 GHz channels.
RFU-D-HP can be used with wide diplexer-based branching, enabling direct mount installation. Diplexers can be used
for direct mount configurations of up to 4+0.
RFU-D-HP can also be used with channel filter-based branching, enabling configurations of up to 8+0 per polarization in
remote mount and all-indoor configurations.
To maximize operational flexibility, both diplexers and channel filters are provided separately for the radio units,
enabling the diplexers or filters to be changed in the field with minimal downtime and no risk of impairing the RFU’s
sealing.
To maximize operational flexibility, both diplexer covers and outdoor circulator units (OCUs) are provided separately
from the radio units, enabling the diplexer covers or OCUs to be changed in the field with minimal downtime and no
risk of impairing the RFU’s sealing.
For all-indoor configurations, the IDU, the RFUs, and the channel filter-based branching system are ordered as a single
item and delivered, pre-assembled, pre-tested, and pre-configured in a rack.
Note
Since all-indoor configurations are pre-assembled and pre-configured, they are not covered in this
Installation Guide.

Note
The voltage at the RSL port is 1.XX where XX is the RSL level. For example: 1.59V means an RSL of -59
dBm. Note that the voltage measured at the RSL port is not accurate and should be used only as an
aid).
For instructions on determining which radio carrier is measured, refer to the User Guide for the IDU
and Release version you are using.
