What is CPRI cable?
CPRI cable is a type of optical cable that features duplex LC connectors on both ends, and it can be shielded or have different covers to accommodate various brands of fiber to antenna (FTAA) applications. CPRI cables can support different types of radio equipment, such as remote radio heads (RRH), distributed antenna systems (DAS), and small cell base stations. CPRI cables also support different types of fiber, such as single-mode and multi-mode, as well as different types of optical transceivers, such as SFP and SFP+. CPRI cables are designed to operate under a variety of environmental conditions, including temperature, humidity, dust, and salt spray, with high reliability and durability.
How CPRI works
The CPRI interface consists of two main parts: user plane and control management plane. The user plane is responsible for transmitting data and signals between the REC and RE, such as IQ data, synchronization signals, and alarm signals. The control management plane is responsible for controlling and managing REs, including configuration, status, performance, and more. The CPRI interface utilizes a time division multiplexing (TDM) scheme to transmit the user plane and control management plane over the same fiber cable. CPRI interfaces support different line bit rates, ranging from 614.4 Mbit/s to 12,165 Gbit/s, depending on the number of carriers, bandwidth, and modulation schemes.
The CPRI interface defines various functional distribution options for physical layer processing between the REC and RE. Functional distribution determines the amount of physical layer processing that occurs on the REC and the amount that occurs on the RE. The data and signals that must be transmitted via the CPRI interface are defined by the CPRI standard, which specifies seven functional allocation options ranging from Option 1, the most centralized, to Option 7, the most distributed. The functional allocation option can be selected based on network requirements, such as latency, bandwidth, and cost.
Conclusion
CPRI cables are a type of optical fiber cable used to connect radio equipment (REC) on cellular base stations to the base station (BS) on the ground. Compared to traditional copper or coaxial cables, CPRI cables offer several advantages, such as higher bandwidth, longer distances, lower attenuation, and reduced costs. CPRI cables are based on the CPRI standard, which defines the key parameters and protocols for communication between the ER and BS. CPRI cables can help wireless network operators optimize their network architecture and improve their network performance.
