摘　　要：Three novel designs of adaptively modulated optical orthogonal frequency division multiplexing modems using subcarrier modulation （AMOOFDM-SCM） are proposed, for the first time, each of which requires a single inverse fast Fourier transform/fast Fourier transform （IFFT/FFT） operation. These designs not only significantly simplify the AMOOFDM-SCM modem configurations, but also offer extra unique network features such as input/ output reconfigurability. Investigations show that these three modems are capable of supporting more than 60 Gb/s AMOOFDM-SCM signal transmission over 20, 40 and 60 km single mode fibre （SMF）-based intensity modulation and direct detection （IMDD） transmission links without optical amplification and chromatic dispersion compensation.Three novel designs of adaptively modulated optical orthogonal frequency division multiplexing modems using subcarrier modulation （AMOOFDM-SCM） are proposed, for the first time, each of which requires a single inverse fast Fourier transform/fast Fourier transform （IFFT/FFT） operation.
