Abstract

Nowadays, the demand for increasing capacity in optical transmission systems is growing to support various new internet applications such as virtual/augmented reality, artificial intelligence, data mining, cloud services, and video streaming. Advances in hardware technologies and the widespread use of technologies like social media have pushed system capacity closer to its theoretical limits. In this study, an Erbium-Doped Fiber Amplifier (EDFA) design was implemented using an optical simulation program. Signal and noise powers at different pump powers (50mW, 100mW, 150mW) were obtained depending on the length of the erbium-doped optical fiber. Subsequently, the physical structure of the EDFA was examined, and the equations for signal power, pump power, and noise figure were solved numerically for various fiber lengths. The results obtained from simulations and numerical methods were compared, showing a strong similarity. It is anticipated that the results of this study can be used to create functional expressions for optimization equations and serve as a resource for future research.

Özet

Sanal/artırılmış gerçeklik, yapay zekâ, veri madenciliği, bulut hizmetleri ve video akışı gibi çeşitli yeni internet uygulamalarını desteklemek için optik iletim sisteminde kapasite artışına olan talep giderek artmaktadır. Son birkaç yılda, donanım seviyesindeki gelişmeler ve sosyal medya gibi teknolojiler yaygın şekilde kullanılmakta bu sebeple sistem kapasitesini teorik sınıra yaklaştırmaktadır. Bu bağlamda araştırmada öncelikle optik simülasyon programı yardımıyla EKFY tasarımı yapılarak sisteme sırasıyla 50mW, 100mW, 150mW pompa gücü verilerek Erbiyum katkılı optik fiber uzaklığına bağlı olarak optik çıkış gücü ve gürültü gücü elde edilmiştir. Sonrasında EKFY fiziksel yapısında, çeşitli uzunluklardaki Erbiyum katkılı optik fiber uzunlukları için sinyal gücü, pompa gücü ve gürültü faktörü denklemleri numerik olarak çözümlenmiştir. Son olarak simülasyon sonuçları ile bulunan nümerik sonuçlar karşılaştırılmış elde edilen sonuçlar görsellerle ve tablolarla sunulmuştur. Karşılaştırma sonuçları analiz edildiğinde büyük benzerlik elde edilmiştir. Bu bağlamda ileriki çalışmalarda, elde ettiğimiz sonuçlar fonksiyon şeklinde yazılarak optimizasyon denklemleri için kullanılabileceği düşünülmekte ve bu tür çalışmalara kaynak olacağı sonucuna varılmıştır.
