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.
