Fig. 7-54: Front panel view (1409.7208.02)
The CPRI breakout board (1409.7208.02) covers two SFP cages, that means sockets to
insert an SFP module, while the variant (1409.7208.04) has a single SFP cage.

SFP (

with the DUT via a fiber glass cable or a copper cable.
These interfaces can be manually adapted by interchangeable slide-in modules and
therefore provide adjustment to the special demand of the applications.
The CPRI breakout board (1409.7208.02) covers two cages, that means sockets to insert
an SFP module, that are standardized according to MSA (

SFP transceivers are available for several communications standards. They support high
data rates in electro optical netwoks and also in fiber optic networks.

Note:
CPRI primarily uses the optical link via the SFP interfaces. Additionally, the break-
out board delivers the signals at these interfaces, e.g., to execute a concurrent monitoring
of the signals. See
chapter 7.2.7.5, "SMA Settings"
, on page 158 to activate the interface
and to set the corresponding parameters.
RS-232-C - Slow C&M Interface
RS-232-C interface for slow transmission of control and management data between the
PC and the CPRI breakout board.
The interface supports bidirectional data transmission of C&M data from a customized
software.
Note:
For transmission of control signals by means of R&S
DigIConf, use the USB con-
nection between the control PC and the R&S
EX-IQ-BOX.
Set the corresponding data source in the Slow C&M (HDLC) panel of R&S
DigIConf
according to your setup.
