ÇİFT GEÇİŞLİ L BAND ERBİYUM KATKILI FİBER YÜKSELTECİN SICAKLIK BAĞIMLILIĞININ İNCELENMESİ

Öz

Bu çalışmada, tek geçişli (SP) ve çift geçişli (DP) L band erbiyum katkılı fiber yükseltecin (L-EDFA) sıcaklığabağımlı kazanç değişimi incelenmiştir. Bu amaçla L-EDFA, 0 °C ile 60 °C arasındaki sıcaklık aralığında, -20dBm güçteki giriş sinyalleri ve 980 nm pompa lazerleri ile iki yönlü pompalanarak deneysel olarak incelenmiştir.Deneysel sonuçlar DP L-EDFA kazancının SP L-EDFA kazancından daha yüksek olduğunu göstermektedir.Ancak sonuçlar aynı zamanda DP L-EDFA’nın sıcaklık bağımlılığının SP L-EDFA’dan daha yüksek olduğunuda göstermektedir. Sonuç olarak, DP L-EDFA’nın 1568 nm - 1588 nm aralığında sıcaklıktan bağımsız olarakçalıştırılabileceği görülmüştür.

Anahtar Kelimeler

• L band, EDFA, sıcaklık bağımlılığı, tek geçiş, çift geçiş.
