Bidirectional free space optical communication (FSO) in WDM access network with 1000-m supportable free space link

Performance analysis of long‐reach 40/40 Gbps mode division multiplexing‐based hybrid time and wavelength division multiplexing passive optical network/free‐space optics using Gamma‐Gamma fading model with pointing error under different weather conditions

“…Furthermore, the comparative performance analysis of the MDM-based hybrid TWDM-PON/FSO with the most recent previous literature works as reported in Table 7 and illustrates that the proposed system presents a superior performance in terms of various performance parameters. Besides, this work shows the significant enhancement as against presented work, where the highest achievable fiber and FSO link range at 5 Gbps data rate under clear weather condition are 25 km and 5 m, respectively, 14 and in another work, 24 where the maximum acceptable fiber and FSO link range is 25 km and 6 m, respectively, at 10 Gbps data rate. In addition, 33 presents the work at 4 × 20 Gbps data rate, where the successful total link distance is 50 km under clear air and heavy fog is 2000 m. Moreover, according to previously reported work, 77 the RB noise would degrade the SNR of approx.…”

“…14 They also investigated a proposed hybrid on-off keying (OOK) WDM-FSO link under the clear atmospheric condition and results show that the good quality bidirectional transmission of 10 Gbps data rate up to 1000 m and 25 km of FSO and fiber link range, respectively. 24 Ahmad Anas et al, 25 describes the impact of hybrid FSO and fiber-to-the-x (FTTx) system to enhance the FSO transmission link range under different atmospheric turbulence and attenuation path-loss. The experimental results show a sustainable bidirectional transmission of 1 Gbps information up to 20 km fiber link and 1.4 km FSO link range.…”

Free Space Optical Communication in Long-Reach Unidirectional Ring-Architecture Fiber Network

“…1. In the previous study [28], the divergency loss of FSO signal between the OWU and ROWU could be simulated under the different free space traffic length based on the designed optical system, assuming the weather condition is clean for outdoor application. So, Fig.…”

Performance of Free-space Optical Communication Systems using Optical Amplifiers under Amplify-forward and Amplify-received Configurations

“…In [11], FSO transmission over a distance of 1 km was successfully achieved with a data rate of 160 Gbps under the scheme of WDM. In [12], FSO transmission over a link distance of 1 km was also achieved at a data rate of 10 Gbps under the WDM scheme. In [13], the successful transmission of data at a rate of 10 Gbps over a link a distance of 5.8 km was reported.…”
