We propose and experimentally demonstrate a simple and cost-effective bi-directional radio-over-fiber (RoF) system for simultaneous transmission of downstream baseband, microwave (MW) and millimetre-wave (MMW) signals based on a single-drive Mach-Zehnder modulator (MZM). Upstream data transmission is realized by re-modulation of the downstream signals.
We propose and experimentally demonstrate a simple and cost-effective scheme to converge a 60-GHz radio-over-fiber (RoF) system with a wavelength division multiplexed-passive optical network (WDN-PON) system. Only 10-GHz electronic devices are used to generate a 60-GHz RoF signal based on frequency-sextupling technology. For n-channel WDN-PON and RoF converged system, only n+1 modulators are required.
