Fifth-generation new radio signal transmission over a transparent fiber-wireless-fiber seamless system in the 75–110 GHz band

【摘要】 In this Letter, we demonstrate the transmission of fifth-generation new radio (5G NR) signals over a fiber-millimeter-wave(mmWave)-fiber mobile fronthaul system in the 75–110 GHz band for an ultra-dense small cell network. The system employs a simple all-optical conversion technology, including mmWave signal generation using an optical heterodyne and a photonicsenabled receiver based on different modulator schemes. As a proof-of-concept demonstration, we successfully transmit400 MHz 64QAM/256QAM at 3.5 and 4.9 GHz. The proposed system can provide a simple solution for facilitating the deployment of ultra-dense small cells in high-frequency bands for 5G mmWave/intermediate-frequency-over-fiber networks.更多还原
