Abstract

The positioning of Erbium-Doped Fiber Amplifiers (EDFAs) plays a crucial role in optimizing the performance of Dense Wavelength Division Multiplexing (DWDM) systems, particularly in addressing signal attenuation challenges in long-distance optical transmission. This study investigates the impact of EDFA placement configurations (booster, in-line, and pre-amplifier) on signal quality using OptiSystem software simulations. The research examines systems with 4 to 16 DWDM channels, operating at 10 Gbit/s per channel with 50 GHz spacing, varying total input power between -10 dBm to 5 dBm. Results demonstrate that the booster amplifier configuration performs best, while the pre-amplifier setup exhibits more pronounced degradation. The in-line amplifier configuration shows a balanced performance, effectively restoring signal strength while requiring less pump power than the booster configuration, making it a viable option for optimizing energy efficiency in DWDM systems. A critical performance threshold was identified between 10-12 channels, where all configurations experience significant changes in error performance.

Özet

Erbiyum Katkılı Fiber Yükselteçlerin (EDFA) konumlandırılması, özellikle uzun mesafeli optik iletimde sinyal zayıflaması sorunlarının çözümünde, Yoğun Dalga Boyu Bölmeli Çoklama (DWDM) sistemlerinin performansını optimize etmede kritik bir rol oynamaktadır. Bu çalışma, OptiSystem yazılım simülasyonları kullanarak EDFA yerleşim konfigürasyonlarının (hat başı, içi ve sonu yükseltici) sinyal kalitesi üzerindeki etkisini incelemektedir. Araştırma, kanal başına 10 Gbit/s hızında ve 50 GHz aralıklı, toplam giriş gücünün -10 dBm ile 5 dBm arasında değiştiği 4 ila 16 DWDM kanallı sistemleri değerlendirmektedir. Sonuçlar, yükseltici amplifikatör konfigürasyonunun en iyi performansı sergilediğini, ön yükseltici kurulumunun ise daha belirgin bir performans düşüşü gösterdiğini ortaya koymaktadır. Hat içi yükseltici konfigürasyonu, yükseltici konfigürasyonuna göre daha az pompa gücü gerektirirken sinyal gücünü etkili bir şekilde geri kazandırarak dengeli bir performans sergilemekte ve bu da onu DWDM sistemlerinde enerji verimliliğini optimize etmek için uygun bir seçenek haline getirmektedir. Tüm konfigürasyonların hata performansında önemli değişiklikler gösterdiği 10-12 kanal arasında kritik bir performans eşiği tespit edilmiştir.
