Abstract

Optical communication technologies in atmospheric layers for non-terrestrial communication applications in 6G communication systems are vital to achieving high data rate capacity. In this context, the use of optical communication systems using the dense wavelength division multiplexing (DWDM) technique is being investigated. In this study, it has been theoretically shown that a 100-channel DWDM hybrid FSO-Fiber optic communication system with 0.21 nm (~26.9 GHz) channel spacing can offer better communication performance compared to 25 GHz and 50 GHz spacing systems. Additionally, a 20 Gbps backhaul link can be realized using high-altitude platform stations (HAPS) for distances longer than 50 km, as shown in the proposed model.

Özet

6G iletişim sistemlerinde karasal olmayan iletişim uygulamaları için atmosferik katmanlarda optik iletişim teknolojilerinin kullanılması, yüksek veri hızı kapasitesine ulaşmak için hayati önem taşımaktadır. Bu bağlamda, yoğun dalga boyu bölmeli çoğullama (DWDM) tekniğini kullanan optik iletişim sistemlerinin kullanımı araştırılmaktadır. Bu çalışmada, 0,21 nm (~26,9 GHz) kanal aralıklı 100 kanallı DWDM hibrit FSO-Fiber optik haberleşme sisteminin 25 GHz ve 50 GHz aralıklı sistemlere kıyasla daha iyi bir iletişim performansı sunabileceği teorik olarak gösterilmiştir. Ayrıca, önerilen modelde gösterildiği gibi, 50 km'den daha uzun mesafeler için yüksek irtifa platform istasyonları (HAPS) kullanılarak 20 Gbps'lik bir ana taşıyıcı bağlantısı gerçekleştirilebilir.
