In this letter, an integrated passive optical network/ millimeter wave (mm-wave) wireless topology is addressed, focusing on mm-wave for beyond 4G in building extension and small-cell mobile backhaul/fronthaul. A simple single-mode fiber/multi-mode fiber (MMF) scheme using conventional central launching or an offset coupling technique is proposed. An experimental study comparing the above coupling schemes is performed using a 1.2-Gb/s ON-OFF keying (non-return to zero) transmission and 60-GHz photonic up-conversion or 5 Gb/s at 60-GHz carrier multiband orthogonal frequency division multiplexing (MB-OFDM) both propagating over OM-1 MMF.
