Abstract

We propose and experimentally demonstrate a novel radio over fiber system that provides different gigabit orthogonal frequency division multiplexing (OFDM) signals transmission for wired and wireless networks using a conventional reflective semiconductor optical amplifier and a single-arm Mach-Zehnder modulator (MZM). To halve sampling speed of electronics and to simplify a radio frequency front-end design, the proposed scheme adopts Hermitian symmetry to generate the wireless signal. It was reported that using the proposed scheme, 5-Gbps 16-quadrature-amplitude-modulation-OFDM wired and 1.17-Gbps quadrature phase-shift keying OFDM wireless signals were successfully transmitted through 23-km standard single mode fiber link.
