Novel ROF network architecture for providing both wireless and wired broadband services

We propose and experimentally demonstrate that a novel and low-cost radio over fiber network architecture for providing wireless and wired dual services at 2.5 Gb/s. The base-band signals are directly detected by a low-cost receiver with a 2 GHz bandwidth low-pass filter, while the RF signals are down-converted by a mixer and an electrical local oscillator signal. Our experimental results show the millimeter wave in this network architecture exhibits less than I dB power penalty over 20 km fiber after providing the dual services.
