Convergent Optical Fronthaul Link for Wireless Access over Different Spectral Bands [Dataset]

[ES] We demonstrate a convergent optical fronthaul link for enabling heterogeneous wireless access technologies in 6G future networks deployment based on a directly modulated laser and an external Mach–Zehnder modulator biased at null point for optical frequency multiplying. Simultaneous transmission of two M-QAM data signals over baseband and millimeter wave (mmW) frequency band, i.e. 42 GHz, is demonstrated over a 10 km fiber link, showing the suitability for visible light communications and mmW radio access, respectively, to the final user. System intermodulation in mmW band is identified under high received optical power levels and overcome by inserting a dispersion compensation module.
