چکیده

Depletion of soliton energy by four-wave mixing between a soliton and amplifier noise in a system with 100-km amplifier spacing is studied. Dispersion exponentially decreasing fiber is used as transmission fiber. Improvement of the system by the use of a sliding-frequency filter to reduce noise power and the depletion of soliton energy is shown. The system can be further improved by compensation for depleted soliton energy.

Four-wave mixing in dispersion-managed return-to-zero systems

Four-wave mixing (FWM) in wavelength-division multiplexed systems with strong dispersion management and loss–amplification is comprehensively studied. The methods described apply to both soliton and quasilinear return-to-zero systems. A linear model is introduced that describes the resonant growth and saturation of the FWM products. The model yields a resonance condition between the channel sep...

Suppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System

Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...

Four-wave mixing in wavelength-division-multiplexed soliton systems: damping and amplification.

Four-wave mixing in wavelength-division-multiplexed soliton systems with damping and amplification is studied. An analytical model is introduced that explains the dramatic growth of the four-wave terms. The model yields a resonance condition relating the soliton frequency and the amplifier distance. It correctly predicts all essential features regarding the resonant growth of the four-wave cont...

Four Wave Mixing Effect in Fiber and Edfa of an Optical Wdm System Having Different Channel Spacing and Chromatic Dispersion Schemes

The performance of an optical wavelength division multiplexed communication system is analyzed taking the four wave mixing (FWM) effect into account. Also it is found that the efficiency of FWM generation can be greatly reduced by making the spacing between channels unequal. Taking into account the various channel spacing schemes and various distribution of different dispersion type optical fib...

\Nonlinear Schrr odinger Equations, Wavelength Divison Multiplexing and Four Wave Mixing" In the limit of large frequency spacing the multisoliton solutions of the nonlinear Schrr odinger equation (NLS), which models the evolution of nonlinear waves in optical bers, are investigated. In Fourier space the individual pulses are found to always be widely separated, and hence can be easily, measure...
