Identify CPRI Configuration
Remote Radio Heads can be connected to the Base Band Unit in different ways. Make
sure which configuration is applicable.
sure which configuration is applicable.
Depending on the actual site configuration, there can be
• up to three RRHs individually connected
• one daisy chain, containing three RRHs
• two daisy chains, each containing three RRHs
• three daisy chains, each containing two RRHs
Each individual connection or daisy chain is connected to one CPRI port of the Base
Band Unit. Depending on the actual configuration the RRHs may need to be
interconnected too.

NOTICE
Protect fiber cable
.
The optical fiber should be protected in solid pipe to proximate of RRH, use twine to
secure the optical fiber in the cable way (neither use tie rap), neither cut this cable on
site, the exceed length should be coil in side and protected in box. The fiber optic
connector should be protected by cap when not being used. Respect the bending radius
during the manipulation of optic cable (82.5mm).
