Optical frequency-interleaving full-duplex multichannel transmission of W-band frequency-modulated continuous-wave downlink signal and 10-Gb/s on-off-keying uplink signal

An optical frequency-interleaving full-duplex multi-channel transmission of W-band frequency-modulated continuous-wave downlink and 10-Gb/s on-off-keying uplink signals is investigated. Two-channel transmission with a flexible wavelength channel selector over 10-km-class fiber-optic network is experimentally demonstrated.
