All-Optical Double Spectral-Efficient RoF Link With Compensation of Dispersion-Induced Power Fading

An all-optical radio-over-fiber (RoF) link with double spectral-efficient transmission and compensation of chromatic dispersion-induced power fading is proposed experimentally demonstrated. At the central office, a commercial dual-polarization quadrature phase-shift keying modulator utilized to produce polarization-multiplexed signal composed two modulated microwave vector signals an unmodulated optical carrier. remote node, by adjusting polarization controller introduce proper phase shift carrier, can be demodulated respectively compensated simultaneously. The performance evaluated error magnitude bit rate.
