All-optical plan for ultra-wideband (UWB) signal generation (positive and negative monocycle) utilizing a nonlinear optical loop mirror (NOLM) is proposed and illustrated. Five UWB signals (1 monocycle and 4 bipolar pulses) are created from the solitary Gaussian optical pulse. The utilization of wavelength specific switch (WSS) – based ROADM goes for powerfully assigning wireless ability to meet quick movement load on interest. Also, the optical-wireless frameworks utilizing the orthogonal frequency division multiplexing (OFDM) regulation configuration are scientifically and tentatively shown to alleviate the chromatic scattering in optical fiber, and overcome multi-way spread and recurrence noticeable all around connections. Data transmission of radio signals on optical transporters is accomplished in the theory. These outcomes contribute to the optical-wireless field.
