In sharing BBUs with Macro Networks scenario, RHUBs share only main control boards with with
RF modules on macro base stations, not baseband processing units.
If one end of the CPRI cable is connected to the DLC connector, the other end connects the BBU or
RHUB through the DLC connector. If one end of the CPRI cable is connected to the ODF adapter,
the other end connects the BBU/DCU or RHUB through a connector corresponding to the adapter.
The connectors include the FC connector, SC connector, and LC connector.
When connecting the CPRI cable to the TX and RX ports of the optical module through connectors
in a cross manner, ensure that one end of a core of the CPRI cable is connected to the TX port and
the other end is connected to the RX port. Figure 6-39 shows how to install a CPRI optical cable for
connecting the BBU and RHUBs.
