Paper Abstract

Using the gain profile of an erbium-doped fiber amplifier (EDFA), it is possible to create groups of wavelength within the C and/or L bands and provide necessary attenuation of the bands to equalize the entire wavelength spectrum. The equalized spectrum of wavelengths using this technique uses one variable optical attenuator (VOA) per band while dynamic channel equalizer (DCE) uses one VOA per wavelength channel. In this paper, modeling of the optimized C+L band EDFA is analyzed. Its integration with the control electronics and 8-channel DCE is proposed for use as a multi-channel dynamically gain controlled optical amplifier with flattened output gain spectra - "Smart Amplifier Solution". In addition, its feasibility for use as a broadband amplified spontaneous emission (ASE) source is discussed. The Optimized Gain Flattened C-band EDFA without gain flattening filters (GFF) and C-band Booster EDFA are presented. The optimization of amplification needs by system design approach is discussed.
