摘要

A new bidirectional wavelength division multiplexing - radio over fiber scheme is proposed with multi optical carrier suppression for simultaneous wired and wireless 1.25-Gbps signal transmission. For downstream signals, all modes of a Fabry Perot laser diode are simultaneously suppressed by a Mach-Zehnder modulator at V_π bias point to mitigate a chromatic dispersion. A reflective SOA is used both for reduction of mode partition noise induced from the Fabry Perot laser diode and for the downstream modulation of each channel. The effect of MPN reduction is verified by measuring RF spectra and phase noises. For an upstream signal, another reflective SOA in BS is used by re-modulation technique, which is verified by measuring both the RF spectra and a dynamic rage of an optical input power to the RSOA. A BER of 10~(-11) for three downlink channels and one uplink channel at 1.25-Gbps are experimentally demonstrated after 23-km SMF transmission.
