A 60-GHz bidirectional radio-over-fiber (RoF) system using two-carrier-injected distributed feedback (DFB) laser is proposed and demonstrated to realize optical single sideband (SSB) modulation for downlink.An injection-locked Fabry-P’erot laser is also carried out to realize wavelength reuse in uplink.Transmission of 2.5 Gb/s on a 60-GHz carrier for downlink and 622-Mb/s baseband signal for uplink are both successfully demonstrated over 50-km single mode fiber without chromatic dispersion compensation.

A 60-GHz bidirectional radio-over-fiber (RoF) system using two-carrier-injected distributed feedback (DFB) laser is proposed and demonstrated to optical single sideband (SSB) modulation for downlink. erot laser is also carried out to realize the wavelength reuse in uplink. Transmission of 2.5 Gb / s on a 60-GHz carrier for downlink and 622-Mb / s baseband signal for uplink are both released for over 50-km single mode fiber without chromatic dispersion compensation.
