Optiwave software can be used in different industries and applications, including Fiber Optic Communication, Sensing, Pharma/Bio, Military & Satcom, Test & Measurement, Fundamental Research, Solar Panels, Components / Devices, etc..
OptiSystem is a comprehensive software design suite that enables users to plan, test, and simulate optical links in the transmission layer of modern optical networks.
OptiInstrument addresses the needs of researchers, scientists, photonic engineers, professors and students who are working with instruments.
OptiSPICE is the first circuit design software for analysis of integrated circuits including interactions of optical and electronic components. It allows for the design and simulation of opto-electronic circuits at the transistor level, from laser drivers to transimpedance amplifiers, optical interconnects and electronic equalizers.
OptiFDTD is a powerful, highly integrated, and user friendly CAD environment that enables the design and simulation of advanced passive and non-linear photonic components.
OptiBPM is a comprehensive CAD environment used for the design of complex optical waveguides. Perform guiding, coupling, switching, splitting, multiplexing, and demultiplexing of optical signals in photonic devices.
The optimal design of a given optical communication system depends directly on the choice of fiber parameters. OptiFiber uses numerical mode solvers and other models specialized to fibers for calculating dispersion, losses, birefringence, and PMD.
Emerging as a de facto standard over the last decade, OptiGrating has delivered powerful and user friendly design software for modeling integrated and fiber optic devices that incorporate optical gratings.

Hi,
I have modeled OFDM based FSO transmission link by replacing optical fiber component with FSO component in OFDM modulator example given with Optisystem 14.2 samples. I am analyzing the effect of increasing link range on the SNR of the received signal (which I have calculated using Electrical carrier analyzer connected to Quadrature modulator at the receiver side).
The SNR reduces with increasing distance (as expected)and after a certain distance gets negative (which should be zero as suggested by previous published literature).Kindly look into my project file and suggest what is wrong with the system. Also, I am not sure if connecting Electrical carrier analyzer to Quadrature modulator is the correct way of computing SNR or not.
I am attaching .osd project file along the mail.
Thanks in advance.
Regards,
Satinder
Hi Satinder,
you plotted SNR in db. so negative sign means the signal is less than the noise which is meaningful.
if you have it in absolute value the lowest value will be zero as you expected.
Hope that clarifies your concern.
thanks
