ABSTRACT:
The device includes a first fiber optic transmitter (FOT) to receive a millimeter wave (MMW) signal and to generate a multiple sideband optical signal, and a second FOT to generate a second optical signal, from a reference signal. A first wavelength division multiplexing (WDM) optical filter is connected to the first FOT to separate a first sideband into a plurality of first sideband channels, and to separate a second sideband into a plurality of second sideband channels, and a second WDM optical filter is connected to the second FOT to separate a reference sideband into a plurality of reference sideband channels. A detector receives the plurality of first sideband channels, to detect an active channel from among the plurality of first sideband channels. Fiber arrays receive the plurality of second sideband channels, and the plurality of reference sideband channels, and an optical coupler generates a combined signal therefrom. A photodetection block receives and processes the combined signal based upon the detected active channel.
