ABSTRACT A radio over fiber (RoF) system with external intensity modulator adopting double side‐band modulation scheme is used for generating dense wavelength‐division multiplexing (DWDM) optical millimeter wave. Carrier is reused for carrying the upstream data. The comb generation technique helps to reduce the number of laser sources that need to be used. The system consists of single‐electrode MZM and an athermal optical interleaver to produce the DWDM millimeter wave. Using this system, the number of light sources can be reduced. The system is compact and cost‐effective utilizing the optical carrier effectively. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:983–986, 2017
