CPRI interface panel kits for connectivity testing
The CPRI panel enables easy RF over CPRI testing at the bottom of the tower, reducing the need for unnecessary tower climbs, thus minimizing maintenance cost and overall OPEX for customers. The RFS CPRI panel is bundled with high-quality fiber optic jumpers from RFS, providing an end-to-end system that includes HYBRIFLEX™ fiber-to-the-antenna DC and F/O solutions.
The rugged, lightweight aluminum CPRI interface panel provides bidirectional continuity and uniformity in attenuation over the full CDWM spectrum while utilizing included optical terminators to reduce optical return loss in the communication link. Engineers can access the transmit data stream or uplink or downlink through a monitor port that does not affect service, eliminating the complications and downtime associated with disconnecting the RRH from the continuous communications optical link.
“With the CPRI interface panel, all testing that was formerly done through tower climbing can now be done at the bottom, including tests such as BBU Emulation, RET Control, PIM Values, Return Loss, RF Spectrum Analysis, Troubleshoot Hunt and Troubleshooting Link. This saves money and time,” said Mohamed Alameh, Regional Product Manager, RFS.
“Our CPRI panel provides an easier way to troubleshoot and test the system, without having to take the system down. By bundling this product with our popular fiber jumpers, we are able to offer our customers a cost-effective ‘whole package’ solution providing our fiber jumpers that are compatible with our HYBRIFLEX cable. Using the same fiber optics from RRU to BBU eliminates any potential compatibility issues that might arise due to different fiber grade.”
The addition of CPRI panels reflects the company’s continued investment in preparing carriers for the demands of both today and the future. MNOs are now looking to Cloud-RAN or Centralized-RAN (C-RAN), a new cellular network architecture for future mobile network infrastructure, which takes full advantage of the CPRI interface panels. The advent of C-RAN, in conjunction with fiber and CPRI, gives MNOs the ability to centralize base station deployments up to 40 km away, enabling low-cost, highly reliable, low-latency and high-bandwidth interconnected networks.
The CPRI panel system can be purchased with either 1 or 3 factory-loaded modules, thus allowing up to 18 CPRI ports in only 1 RU of space, claiming to be the densest and most compact on the market today, fully aligned with C-RAN applications.
The CPRI module, chassis, fiber management box and jumper kit can be purchased as standalone items in addition to the bundled kit. This level of flexibility enables customers to build modular, scalable kits that future-proof their networks, and also enables them to move the CPRI from the site to the C-RAN as networks evolve.
