analysis of fwm penalties in dwdm systems base on g 652, g 653, and g 655 optical fiber

... This paper then investigates the FWM penalties imposed on DWDM systems based on G. 652, G. 653, and G. 655 fibers, considering equally spaced channel grids of 100, 50, 25, and 12.5 GHz. Also, the ... based on DSF fibers. . Keywords DWDM systems, Four-Wave Mixing (FWM) , G. 652, G. 653, G. 655 compliant fibers, Signal-to-noise ratio. I. INTRODUCTION...
