What is CPRI Cable and Why You Need It for Your Wireless Network?

January 2, 2024

What is CPRI cable?

CPRI cable is a fiber cable which with duplex LC connectors for both side, but it can be armored or with different cover for different brand fiber to the antenna (FTTA) applications. CPRI cable can support different types of radio equipment, such as remote radio heads (RRH), distributed antenna systems (DAS), and small cells. CPRI cable can also support different types of optical fibers, such as single mode and multimode, and different types of optical transceivers, such as SFP and SFP+. CPRI cable can operate in various environmental conditions, such as temperature, humidity, dust, and salt mist, and have high reliability and durability.

CPRI Cable: How It Works

The CPRI interface consists of two main parts: the user plane and the control and management plane. The user plane is responsible for carrying the data and signals between the REC and the RE, such as the IQ data, the synchronization signals, and the alarm signals. The control and management plane is responsible for controlling and managing the RE, such as the configuration, the status, and the performance. The CPRI interface uses a time division multiplexing (TDM) scheme to transmit the user plane and the control and management plane over the same optical fiber cable. The CPRI interface supports different line bit rates, ranging from 614.4 Mbit/s to 12.165 Gbit/s, depending on the number of carriers, the bandwidth, and the modulation scheme.
The CPRI interface defines different functional split options for the physical layer processing between the REC and the RE. The functional split determines how much of the physical layer processing is done at the REC and how much is done at the RE. The functional split also affects the amount of data and signals that need to be transmitted over the CPRI interface. The CPRI standard defines seven functional split options, from option 1 to option 7, with option 1 being the most centralized and option 7 being the most distributed. The functional split option can be chosen based on the network requirements, such as the latency, the bandwidth, and the cost.

Conclusion

CPRI cable is a type of optical fiber cable that is used to connect the radio equipment (RE) at the cell sites with the base station (BS) at the ground. CPRI cable has many advantages over the traditional copper or coaxial cables, such as higher bandwidth, longer distance, lower attenuation, and lower cost. CPRI cable is based on the CPRI standard, which defines the key parameters and protocols for the communication between the RE and the BS. CPRI cable can help wireless network operators to optimize their network architecture, improve their network performance.
