Abstract

We proposed and demonstrated a novel full-duplex radio-over-fiber system using an optical phase modulator and optical interleaver to generate DWDM optical millimetre wave for carrying downstream data and wavelength reuse for uplink connection. Since the optical phase modulator we used has not a dc-bias controller, and the optical interleaver is not as sensitive to temperature as a fiber Bragg grating, the stability of the generated DWDM optical millimeter wave is largely improved, and the optical power is effectively utilized because the remaining optical carriers with high power have been reused. Moreover, the limitation of chromatic dispersion is greatly reduced due to avoiding the generation of higher order sidebands via driving the phase modulator with optimized RF signal. So this system shows cost-efficient configuration and good performance over long-distance delivery.
