LAP Lambert Academic Publishing Performance Modeling of Hybrid Fiber Amplifiers for DWDM Systems

In this world of globalization, there is a constant need of expanded transmission capacity. This present scenario has lead to the demand of ever increasing bandwidth so as to accommodate more number of channels. To increase the transmission capacity of a single fiber, Dense Wavelength Division Multiplexing (DWDM) is one of the best possible solutions. The implementation of DWDM system requires a variety of passive and active devices to combine, distribute, isolate and amplify optical power at different wavelengths. In DWDM system, it is desirable to set a very narrow grid of optical carriers in order to allow more channels in the same optical bandwidth. This not only demands an optical amplifier with high gain but also very broad and flat gain profile to ensure a nearly identical amplification factor in every channel. This book deals with modeling of optical hybrid amplifiers for 96 channels DWDM Systems(S+C Band)
