CPRI configurations
Star or Daisy Chain solution
The solution is a distributed architecture composed of two optical interfaces located in:
The digital NodeB
The RRH
The optical modules are connected by optical fibers that carry:
Downlink and uplink base band digital signals
OAM information
The daisy chain allows to connect RRHs on one single optical link connected to the
digital Node B part.
In the star configuration the BBU is the central node that provides the common
connection point for all connected RRHs.
This figure shows the star and daisy chain configuration:
Different capabilities and configurations are supported, depending on whether the RRH
2X60W is connected to a 9396 d2U or to a 9926 d2U.
For RRH 2X60W on 9396 d2U, the configuration that is supported is the star
configuration with single frequency on the first Power Amplifier (PA 1).
