Abstract
The broadband penetration and continuing growth of Internet traffic among
residential and business customers are driving the migration of today's end
user's network access from cable to optical fiber and superbroadband
wireless systems The integration of optical and wireless systems operating
at much higher carrier frequencies in the millimeter-wave (mm-wave) range 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 very high throughput wireless-over-fiber networks are
reviewed, including photonic mm-wave generation based on external modulation
or nonlinear effects, spectrum-efficient multicarrier orthogonal
frequency-division multiplexing and single-carrier multilevel signal
modulation. We also demonstrated some applications in wireless-over-fiber
trials using these enabling techniques. The results show that the integrated
systems are practical solutions to offer very high throughput wireless to
end users in optically enabled wireless access networks.
