“…To address this issue based on either adaptive modulation or adaptive coding in IM/DD PON or C-PON. The adaptable C-PON can provide greater optimized capacity with a larger power budget and dynamic range (Mallick et al 2022;Zhang et al 2023).Recently, various C-PON systems have attracted keen interest as it carries the benefits of flexibility, high capacity, and cost-effectiveness. Costa C et al proposed a dual-polarization 16-ary quadrature amplitude modulation (DP-16QAM) C-PON using 4D clustering over a 151.6km transmission distance at 100Gbps data rate (Costa et al 2023).Jung SM et al demonstrated wavelength-reused full-duplex reflective C-PON over a 73km distance at a 12Gbps transmission rate(Jung et al 2018).Kodama T et al introduced a C-PON system having Iand Q-axis mapping for distinct ONUs over 57km transmission distance at 10Gbps data rate(Kodama and Arai 2021).Ju C et al proposed an effective adaptive equalization design for C-PON over 20km single mode fiber (SMF) at 100Gbps data rate successfully (Ju et al 2020).Further, to enhance the optical signal-to-noise ratio (OSNR) tolerance, a probabilistic shaping QAM (PS-QAM) has aroused a lot of interest.…”

A smooth evolution of 16×100Gbps hybrid mode division multiplexing (MDM)/coherent-next generation passive optical network (C-NGPON) system based on wavelength complement coding is proposed. Probabilistically shaped quadrature amplitude modulation (PS-QAM) modulation established alone as the key solution to embrace advanced coherent transponders. The simulation results show that the proposed hybrid MDM/C-NGPON system can offers a high split ratio of 512 in uplink and 256 in downlink as compared to conventional passive optical networks (PONs). For legacy PON signal coexistence with PON signals as well as complement signal the minimum received power of -19dBm for uplink and − 9dBm for downlink can be obtained effectively. Also, optical to signal noise ratio (OSNR) of 20dB can be achieved forPS-512QAM as compared to uniform-shaped 128QAM at 10KHz laser linewidth and it also offers power penalty of 0.5dBunder normalized generalized mutual information (NGMI) limit of 0.857. In addition, the system offers a long-haul transmission distance of 250km considering a shaping factor of 4.7 in uplink and 4.8 in downlink, at NGMI limit. Besides this, the system throughput upto 800Gbps for uplink and 700Gbps for downlink can also be obtained successfully. Finally, it is shown that proposed work shows superiority over other existing systems.

In this work, a radio over free-space optical communication (Ro-FSO) link has been examined considering quadrature amplitude modulation (64-QAM) based orthogonal frequency division multiplexing (OFDM) technique for a turbulence channel. The performance of the system has been investigated considering log normal and gamma-gamma atmospheric scintillation models under clear air, rain and fog weather conditions. Artificial neural network (ANN), k-nearest neighbour (KNN), and decision tree (DT) machine learning (ML) techniques have been applied for estimation of quality of received signal in terms of bit error rate BER. ANN model exhibits the highest value of R-squared (R2) of 0.9967 and lowest value of root mean square error (RMSE) of 0.0134 as compared to other ML techniques resulting in the best fit model.
