2. Verifying provisioning of an RRU with RF over CPRI Spectrum
Analysis
Follow this procedure to set up a T-BERD and test a CPRI link and RRU, and perform RF over CPRI
Spectrum Analysis for PIM detection and Diversity Imbalance. The test may be run on dark fiber or
through Layer 1 network elements such as transponders and multiplexors. The CPRI Radio Equipment
should be installed at the far end on the link before testing.
Note: This is a dual port application. Port 1 is used by default

Details
Press the ON/OFF button to turn on the T-BERD.
Insert an SFP or SFP+ that supports the Wavelength, CPRI rate and
range of the line under test into the T-BERD 5800v2's Port 1 SFP+ slot.
Note: All SFPs do not support CPRI. Use a Viavi approved CPRI
SFP (see Appendix A) or one approved by your CPRI network
equipment manufacturer.
Ensure that fiber and connectors are clean using a Fiber Inspection
probe.
Connect the SFP or SFP+ to the CPRI port under test using
yellow Single Mode Fiber jumper cables (LC-LC).
You may need to attenuate the signals if you are using a
long range SFP/SFP+.
