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.

Which modulation format is better or suitable for Passive optical networks eg GPON or TWDM PON? Some papers tend to say RZ is better while NRZ is considered as a standard by ITU T.
Hi Shahbaz;
I think NRZ is better than RZ according to their performance in optical systems and that is clear by eye diagram that is clearer, when we use NRZ, than RZ (look at the attached photo) which makes Q- factor is bigger in NRZ.
For more information about your question you can make a look on the attached file.
Regards,
Thanks Namera. Is the eye diagram attached for RZ appropriate? It forms X type of shape below or it can be like this aswell?
Hi Shahbaz,
Both have advantages and disadvantages. But NRZ encoding schemes are probably more convenient to use according to the current protocols and standards, so it is not just because NRZ might show better results.

Thanks Alistu. I understand. But the eye diagram attached by Namera for RZ is acceptable? or does it always have to look like the attached one.
It seems to be acceptable. The eye opening is good, and the Q-factor obtained also shows this. I have attached a file in you other topic regarding RZ signal modulation scheme which might be of more help to you. Please have a look at it here: https://optiwave.com/forums/topic/eye-diagram-for-rz/#post-25657
