Kerr Effect Based Spectrum Sliced Wavelength Division Multiplexing For Free Space Optical Communication

Abstract The super-continuum spectrum sliced WDM FSO system is evaluated at 2.5 Gbps data rate up to link distance of 5 Km. A Highly Nonlinear Fiber (HNLF) is channel for the generation of high power broad spectrum for spectrum slicing. A dense SS-WDM is investigated at 75 GHz channel spacing among 4 channels to make system bandwidth efficient. Performance of SC-SS-WDM and WDM is scrutinized for FSO system under rain, fog, haze etc. Wavelength division free space optical system exhibits more error at 5 Km as compared to spectrum sliced WDM FSO system. Also, the demonstrated architecture is accommodative, flexible and low cost system that can perform well under atmospheric turbulences.
