Radio over fiber is a very attractive technology for delivering microwave and millimeter-wave signals containing broadband multimedia services. The generation of an optical double-sideband with suppressed carrier signal is a straightforward method because only one microwave modulator driven at half the millimeter-wave frequency is required. Then only one sideband is modulated with 10 Gbits/s baseband data forming a millimeter-wave single-sideband signal. Transmission experiments prove this modulation scheme to be dispersion tolerant, and error-free transmission is demonstrated after 21 km of single-mode fiber and wireless links up to 2.5 m.
