“…For the proposed PON, the impacts of quantization bits and signal clipping on the BER performance are very similar to those reported in [15]. For fair transmission performance comparisons with the results presented in [14], in this paper, DAC/ADC quantization bits of 8 are chosen, which can be further reduced to approximately 5 without considerably degrading the optical back-to-back transmission performance [15]. From the parameters in Table 1, an identical upstream net bitrate of 6.25Gb/s can be calculated for each sub-band.…”

“…For a transmission distance range as large as large as 50km, these performance improvements vary by <18% and are robust to finite digital filter tap-induced channel interferences. The aforementioned performances of the proposed PON are similar to those of a recently published PON termed hybrid single sideband OFDM-DFMA PON [15], whose ONU DSP complexity is, however, significantly higher than the proposed PON.…”

Known hybrid orthogonal frequency division multiplexing-digital filter multiple access (OFDM-DFMA) PONs show promise of seamless and cost-effective convergence of optical and mobile networks for 5G and beyond. This paper reports, for the first time, a new hybrid OFDM-DFMA PON based on intensity modulation and direct detection (IMDD), obtained by modifying digital signal processing (DSP) algorithms embedded in both the OLT and ONUs. The proposed PON allows two spectrally overlapped sub-bands to occupy each individual sub-wavelength spectral region to independently transmit upstream ONU information. A model of the proposed PON is developed and its upstream transmission performances are numerically explored for different application scenarios. Compared with the previously published PON, the proposed PON doubles the number of supported ONUs and provides >1.7-fold aggregate upstream signal transmission capacity increases with <1.5dB upstream power budget degradations. Alternately, for the same ONU count, >2.2-fold aggregate upstream signal transmission capacity increases and >0.7dB upstream power budget improvements are achievable. The performance improvements vary by <18% for a transmission distance range as large as 50km. In addition, the proposed PON is tolerant to finite digital filter tap length-induced channel interferences.
