Demonstration of a FPGA-based CPRI-over-ethernet real-time system achieving 120 Gb/s throughput over a 10-km SSMF link with 16 bi-directional 10GE connections

摘要

We experimentally demonstrate a real-time CPRI-over-Ethemet system for mobile fronthaul using four Xilinx Virtex-7 FPGAs. Error-free transmission over a 10-km SSMF link has been achieved with a total throughput of 120 Gb/s and a round-trip processing latency of <;20 μs.
