Selective delivery of gigabit‐per‐second wireless and wired services is demonstrated in an integrated fiber‐wireless access network using the millimeter‐wave (mm‐wave) radio‐over‐fiber (RoF) system employing the dual‐sideband optical carrier suppression technique. A dual‐electrode Mach‐Zehnder modulator is used in this technique to generate 40 GHz carrier to distribute 1.25 Gbps data via direct modulation (DM) over a 20 km RoF system. The results show that selective signal delivery can be achieved using a low‐cost DM laser diode drive current of 20 mA. The advantage of the proposed system is that it provides versatility to control the gigabit‐per‐second (Gbps) signal delivery in an integrated ROF‐PON system with a common high frequency oscillator shared for the whole system. © 2016 Wiley Periodicals, Inc.
