CPRI LTE RF Analyzer and BBU Emulator : CPRI LTE RF Analyzer : Typical CPRI Connection
Typical CPRI Connection
1. Lock down the RRH before disconnecting the fiber optic cable.
2. Disconnect the fiber cable from the BBU.
3. Connect the RRH to Port B on the optical TAP.
4. Connect a 3‑meter LC/LC Duplex Jumper from Port A on the optical TAP to the BBU.
5. Use a compatible SFP transceiver and Simplex fiber cable to connect the Anritsu test instrument to Port AB on the optical TAP.
Port A Out from Port AB is the downlink BBU signal.
Port B Out from Port AB is the uplink RRH signal.
6. If your test instrument has dual SFP ports, you can optionally connect it to another RE, using the second port.
7. When all connections are complete, unlock the RRH.
8. Perform measurements using live traffic.

Laser radiation may be present at fiber optic cable connectors and ports. This laser radiation could present a nominal ocular hazard from either direct viewing or by diffuse reflection. Do not view the emitted laser radiation directly or indirectly because permanent blindness may result.
