Abstract
A new wavelength division multiplexed-radio over fiber (WDM-RoF) access
network scheme supporting the simultaneous transmission of a 1.25-Gb/s wired
data as well as a 1.25-Gb/s wireless data is proposed in this paper. An
optical carrier suppression effect and sideband routing using the
multiplexing of arrayed waveguide grating (AWG) with 50-GHz channel spacing
are utilized to generate a millimeter wave band carrier. These techniques
make the proposed architecture transmit both a wired data and a wireless one
at the same time. A reflective semiconductor optical amplifier (RSOA) is
employed at both central office and base station so that this architecture
is operated colorlessly. Error free transmissions (BER of $10^{-9}$) of both downlink and uplink are achieved simultaneously. A rare
impact of downlink transmission on the performance of uplink data is
observed due to the usage of the unmodulated light.
