Performance Evaluation of 6-Gbps Hybrid DWDM/Multibeam Free-Space Optical Network in an Unusual Haze
To prevail against atmospheric attenuation considering unusual haze in tropical areas and to scale the growing demand for high capacity communication bandwidth and scalability, a prominent technique is used known as dense hybrid wavelength division m

A new four-wave mixing scheme to practically measure the non-linear coefficient of fibers is introduced. A single erbium-doped fiber amplifier is used to create the two wavelengths for the four-wave mixing inputs, which are pre-spectrally sliced via
