980 nm ve 1480 nm'de ileri, geri ve çift yönlü pompalanmış uzun dalgaboyu bandı (L-Bandı) erbiyum katkılı fiber amplifikatörlerin spektral kazanç ve gürültü faktörü karakteristikleri kıyaslanmıştır. Gerçekleştirilen simülasyonlar, L-Bandı EDFA'nın kazanç bandgenişliği ve spektral gürültü faktörü karakteristiklerinin pompalama dalgaboyu ve erbiyum katkılı fiber uzunluğuna bağımlı olduğunu göstermektedir.
Spectral gain and noise figure characteristics of long wavelength band (L-band) erbium doped fiber amplifiers pumped at 980 nm and 1480 nm are compared for different pumping configurations: forward, backward and bidirectional. Simulations performed show that gain bandwidth and spectral noise figure characteristics of L-band EDFAs strongly depend on pumping wavelength and erbium doped fiber length.
