CIPRI stands for Common Public Radio Interface. It is a specification that defines the communication protocol between the baseband unit (BBU) and the remote radio unit (RRU) of cellular radio access networks. CIPRI cable is the fiber-optic or electrical cable that carries the CIPRI signals between the BBU and the RRU. CIPRI cable enables the transmission of digitized radio data and control information over long distances, with high speed and low latency. CIPRI cable is used for various generations of wireless networks, such as 3G, 4G, and 5G.
Some of the main features and benefits of CIPRI cable are:
• It supports multiple radio standards, such as GSM, WCDMA, LTE, and NR.
• It supports various channel bandwidths, from 1.25 MHz to 100 MHz.
• It supports various data rates, from 614.4 kbps to 24.33 Gbps.
• It supports various transmission media, such as single-mode fiber, multimode fiber, coaxial cable, and twisted pair cable.
• It supports various network topologies, such as point-to-point, point-to-multipoint, and ring.
• It reduces the signal degradation and interference caused by the traditional coaxial cable connection.
• It improves the flexibility and scalability of the network deployment and management.
CIPRI cable is a key component of the cellular radio access network that enables the separation and integration of the BBU and the RRU, which can enhance the performance and efficiency of the network communication and services.
