Transmission Techniques for Ultra Dense Wavelength Division Multiplexing by Using Two Optical Amplifiers in Nonlinear Optical Networks

In the present paper, the problem amplification techniques of Ultra Dense Wavelength Division Multiplexing (UDWDM) in nonlinear optical networks are investigated through five transmission techniques. The impact of tailoring of chirped pulses of different temporal waveforms is investigated in a normal dispersion fiber. The set of multiplexed signals are tailored in a different a subset to assure approximately the same output level of power to hold the signal-to-noise ratio at the same level.
