Long-reach MMWoF using single-sideband modulated dual-mode VCSEL with 16-QAM OFDM at 8 Gbit/s

39-GHz millimeter-wave-over-fiber (MMWoF) based long-reach PON with a dual-mode VCSEL transmitter under single-sideband modulation is demonstrated for 8-Gbit/s 16-QAM OFDM transmission over 50-km single-mode fiber and 1-m free-space with BER of 3.6×10−3.
