10Gb/s downstream and 6Gb/s upstream over 40km SSMFs are feasible for double-sideband AMOOFDM signals in wavelength-reused bidirectional-transmission colorless-WDM-PONs incorporating SOA/RSOA intensity modulators in OLTs/ONUs. Such performances are improved to 23Gb/s downstream and 8Gb/s upstream when single-sideband subcarrier-modulation is utilized.
Detailed numerical investigations are undertaken of wavelength reused bidirectional transmission of adaptively modulated optical OFDM (AMOOFDM) signals over a single SMF in a WDM-PON incorporating a SOA intensity modulator and a RSOA intensity modulator in the OLT and ONU, respectively. A comprehensive theoretical model describing the performance of such network scenarios is, for the first time, developed,...
An adaptively modulated optical orthogonal frequency division multiplexing (AMOOFDM) modem using subcarrier modulation (SCM) (AMOOFDM-SCM) is proposed, for the first time, which consists of two conventional AMOOFDM modems in parallel with one operating at the baseband and the other being modulated onto an intermediate radio frequency (RF) carrier. Numerical simulations of the transmission performance...
