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.
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.
OptiFiber 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.
Modal analysis is a pivotal component of modelling optical structures. OptiMode serves as a robust CAD platform for the design and modal analysis of waveguide structures.

I have noticed a few parameters in your system that need to be changed. First of all, the number of cyclic prefix points should be the same both for OFDM modulators and demodulators. Second, The value of symbol rate should be set according to the coding scheme in layout parameters and in OFDM blocks. Please see if these help.
You’re welcome. Can you please upload the new .osd file in which you have made the aforementioned changes? I also believe the bandwidth of some of the filters is a bit more than what is required, but even so the system is supposed to work properly after the above changes are applied to it.
having done the changes that I suggested, you have very clear constellation diagrams, which shows transmission is done correctly. However, in order to overcome the symbol rotation, you can change the receiver laser phase so that constellation points fall into the correct quadrants.
Please see if the change in the laser makes the BER zero when the constellation points are all in their corresponding quadrant for your 16-QAM and 64-QAM implementations. Otherwise, the problem you are facing may be due to the fact that OS12 OFDM components have been used in your design.
Hi Ranjeet, Thank you very much. I find your implementation quite helpful.
Mukalla, The file attached by Ranjeet is quite helpful for your purpose. The thing is, it is a bidirectional system due to being implemented as a passive optical network. But you can easily make changes to make it suitable for your own purpose if bidirectionality is not desired.
Ranjeet’s file is a simulation of a bidirectional OFDM system and is designed for the purpose of being used in passive optical networks, while your simulation should be unidirectional. So I suggest you eliminate parts of the system corresponding to upstream data to have the unidirectional system.
