“…In [8], the WDM and OAM techniques were integrated at a 1.6 Tbps data rate. A hybrid OAM, WDM, and orthogonal frequency division multiplexing passive optical network (PON) was designed over 40 km MMF at 40 Gbps throughput in another study [9]. OAM 31 and OAM 41 modes are used in [10] to realize an OAM-MDM system over a ringcore fiber range of 300 km and at a 20 Gbps data rate.…”

With their unique capability to deal with a considerable geographic area, satellite–ground–underwater optical wireless communication (OWC) systems are an appealing alternative to meet the ever-increasing demand for end-to-end broadband services. Using four different Laguerre–Gaussian (LG) modes, an orbital angular momentum (OAM) multiplexing method was developed to enhance the spectral efficiency and system capacity of the satellite–ground–underwater OWC system. At an aggregate throughput of 160 Gbps, LG[0,0], LG[0,2], LG[0,4], and LG[0,8] were realized. Various atmospheric conditions, water types, and scintillation effects were used to evaluate the performance of two separate OWC links for satellite-to-ground and ground-to-underwater communication. A maximum OWC range of 21,500–30,000 km has been obtained under weak-to-strong turbulence for satellite-to-ground scenarios, and a range of 12–27 m underwater for ground-to-underwater scenarios under various scintillation effects. At LG[0,0], in pure sea, the maximum gain is −75.02 dB, the noise figure is 75.02 dB, the output signal is −78.32 dBm, and the signal-to-noise ratio is 21.67 dB. In comparison with other works in the literature, this system shows a superior performance.

The unique advantage of orbital angular momentum (OAM) provides a novel approach to breaking through the limitations of high‐capacity and long‐distance transmission in the conventional radio‐overfiber passive optical network (RoF‐PON) hybrid access network. Introducing the OAM division multiplexing (OAM‐DM) based on Laguerre–Gaussian (LG) beams into the RoF‐PON, an innovative multidimensional system architecture is proposed, which integrates with polarization‐division multiplexing (PDM), wavelength‐division multiplexing (WDM), and orthogonal frequency‐division multiplexing (OFDM) technologies. Successful long‐distance transmission of both the downstream 40 GHz radio OFDM signal and the upstream 40 Gbps on‐off keying (OOK) signal over 80 km are achieved. Additionally, at the optical network unit side, low‐cost upstream carrier re‐modulation technology and flexible access for both wired and wireless signals are realized. The proposed RoF‐OAM‐DM‐PDM‐WDM‐OFDM‐PON architecture offers a dependable solution for high‐capacity and low‐cost future communication systems, holding great importance in achieving flexible access networks.

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.
