Abstract
The integration of optical and wireless systems is considered to be one of the most promising solutions for
increasing the existing capacity and mobility as well as decreasing the costs in next-generation optical access
networks. In this paper, several key enabling technologies for hybrid optical–wireless access networks are
described, including optical millimeter-wave (mm-wave) generation, upconversion, and transmission in a downlink
direction, and full-duplex operation based on wavelength reuse by using a centralized light source in an uplink
direction. By employing these enabling technologies, we design and experimentally demonstrate an
optical–wireless testbed that is simultaneously delivering wired and wireless services in the integrated
optical–wireless and wavelength-division-multiplexing passive-optical-network access networks. The actual
applications consisting of 270-Mb/s uncompressed standard-definition TV signal and 2.5-Gb/s data channels for
downstream are successfully transmitted over a 25-km fiber and a 10.2-m indoor wireless link with less than a 1.5-dB
power penalty. The results show that this integrated system is a practical solution to deliver superbroadband
information services to both stationary and mobile users.
