Abstract

To simultaneously modulate and transmit 10-Gb/s baseband and 20-GHz microwave signals on a single wavelength using single-sideband (SSB) modulation technique, a novel ROF scheme is proposed and verified by simulation. Based on a Dual-Parallel Mach-Zehnder Modulator (DPMZM) the scheme can carry the microwave signal on the upper sideband(USB) and the baseband signal on the lower sideband(LSB). It is to be seen from the simulated results that the crosstalk between the signals with dual services is very small. By means of subcarrier-multiplexing (SCM) technique, the optical 20-GHz microwave wave carrier is generated to carry 155-Mb/s baseband signal and 10-Gb/s baseband signal is imposed on the original optical carrier via SSB modulation. The simulated results of BER and the eye diagram are achieved separately. The signals with dual services are successfully transmitted over 50-km single-mode fiber.
