Abstract
Limitations imposed by Four-Wave Mixing (FWM), Amplified Spontaneous Emission (ASE), dispersion and Stimulated Raman Scattering (SRS) on a multi-spam DWDM system are theoretically studied. In this work, expression for the linear dispersion parameter D has been defined as a function of number of channels in order to separate FWM and SRS effects and calculates both maximum fibre length and optimum power. Additionally, our simulation results consider the effect of ASE noise from Erbium Doped Fibre Amplifiers (EDFAs). This theoretical analysis yields a set of design criteria from optimized multi-span DWDM systems.
Highlights
Long distance high capacity optical transmission is achieved using optical fibre links in backbone of terrestrial and transoceanic communication systems
We have explored the limitations of a multi-span Dense Wavelength Division Multiplexing (DWDM) system imposed by Four-Wave Mixing (FWM), Amplified Spontaneous Emission (ASE), dispersion and Stimulated Raman Scattering (SRS) for up to 100 channels
We have determined the conditions under which DWDM systems will be limited mainly by FWM and ASE, or SRS and ASE separately and altogether
Summary
Long distance high capacity optical transmission is achieved using optical fibre links in backbone of terrestrial and transoceanic communication systems. Expression for the linear dispersion parameter D has been defined as a function of number of channels in order to separate FWM and SRS effects and calculates both maximum fibre length and optimum power. Design parameters for multi-span DWDM system limited by FWM, SRS and ASE noise are proposed.
