Journal ArticleDOI
Investigation and Demonstration of High Speed Full-Optical Hybrid FSO/Fiber Communication System Under Light Sand Storm Condition
TL;DR: In this paper, the authors used a 12 subcarrier comb generator, each of which is modulated by a quadrature-amplitude modulation (QAM) signal and achieved a 1.08 Tbps error free data rate with 3.6 b/s/Hz spectral efficiency.
Journal ArticleDOI
Machine Learning Techniques for Optical Performance Monitoring and Modulation Format Identification: A Survey
TL;DR: A comprehensive review of the available ML-based techniques for MFI, OPM, and joint MFI/OPM, describing their performance, advantages, and limitations and some lessons learned are presented to help the reader identify the gaps, weaknesses, and strengths.
Journal ArticleDOI
5G-28 GHz Signal Transmission Over Hybrid All-Optical FSO/RF Link in Dusty Weather Conditions
TL;DR: The results demonstrate that the all-optical FSO link is significantly affected by low visibility range, with severe bit-error-rate (BER), and error vector magnitude (EVM) limits appearing at a 50-m visibility range for a 2.7-m channel length.
Journal ArticleDOI
Experimental Demonstration of Simultaneous Modulation Format/Symbol Rate Identification and Optical Performance Monitoring for Coherent Optical Systems
TL;DR: A cost-effective technique that not only exhibits optical performance monitoring functionalities but also enables simultaneous symbol rate and modulation format identification, based on artificial neural networks in conjunction with asynchronous amplitude histogram (AAH) evaluation.
Proceedings ArticleDOI
Performance analysis of next generation-PON (NG-PON) architectures
Amr Ragheb,Habib Fathallah +1 more
TL;DR: A comparison between key network specifications such as data rates and power budget has been reported, and different state-of-the-art technologies that will potentially be used for NG-PONs are studied.
