L-Band Flat-Gain Raman with Erbium-Doped Fluoride Hybrid Optical Amplifier for Superdense Wavelength Division Multiplexing System

Аннотация

To the best of our knowledge, we explore, for the very first time, the performance using Raman-EDFFA hybrid amplifier for super dense multiplexing system. We evaluate the system in terms of flat gain, noise figure, and good rating quality factor for L-band. A highest flat gain of 26.01 dB is observed over a wavelength range of 1,578 to 1,640 nm with a smaller variation of 1.5 dB without using any cost influence techniques. Further, we also observe that an input power level of −25 dB is quite suitable for acceptable amplification.
