Integrated Wireless and Wired Signal in the Hybrid Access System

Abstract

To meet the demands of different high bandwidth services, we demonstrated a hybrid access network simultaneously transmitting wired and wireless signals. In the downstream, wireless signals are modulated and transmitted in phase modulation format at the optical carrier and wired signals are re-modulated in intensity modulation format, different de-modulation schemes are used at optical network unit (ONU) side; In the upstream, carrier reuse technology are adopted to re-modulate and transmit uplink signals to the optical line terminal (OLT). Simulation results show user ends could get acceptable performance of the wirless and wired signals.
