Abstract

The interminable need of number of channels in communication systems escorts more number of wavelengths to be used. This broad spectrum of wavelengths when expands in both C and L band, the need of hybrid optical amplifiers (HOA) comes into play. In this work, we proposed an automatic gain-controlled HOA using Residual pumping for C/L band. The desired gain is fixed at 27 dB at pump power swinging between 300 and 400 mW. The input powers are automatically adjusted so as to provide invariable and flat gain eliminating the wavelength dependency of optical amplifier to great extents. Analysis is carried out in a 32 channel WDM system and power transients are also measured in terms of powers of surviving channels and excursion amplitudes by adding and dropping up to 28 channels. The output is adjudicated in terms of maximum gain achieved, OSNR, BER, gain flatness, noise figure and power transient excursion amplitudes.
