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.

What system block should I use for quadrature audio data modulation (QADM) in electrical domain using optisystem 13.
With regards,
Dhiman Kakati
Dear Dhiman,
Can you please elaborate more about quadrature audio data modulation. I hope you mean Quadrature amplitude modulation?
I tried google the term quadrature audio data modulation (QADM) but did not find relevant documents regarding the same.
Thanks for your reply, I also didnot find details about quadrature audio data modulation, But when I searched QADM (as in attached block diagram image) i Google I found it to be “quadrature audio data modulation”.
If u have another suggession please help me. Please go through the attached pdf and image.
With regards
Please find the attached snapshot.
Dear Dhiman,
I think you have been mistaken. Instead of quadrature audio data modulation it is Quadrature amplitude demodulator block. If you check your block diagram you will find the QAM block and the opposite end it is QADM block.
The QAM stands for quadrature amplitude modulator and QADM for Quadrature amplitude demodulator. Hope this helps.
Thank you Dhananjay for your suggestion. This actually makes more sense, since QADM has actually been used in all receiving points and QAM on all transmitting sides of the schematic snapshot attached. Otherwise it would be strange to use different coding schemes for the transmission and reception.
Thanks a lot for your help. I hope you are right as I was not sure about it.
