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.
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.

in ber analyzer results there is a element called “penalty:Q factor from Min.BER at user defined decision instant(dB)”
what does It mean? is it same as “max Q factor” can we use it to express the quality of transmission?i have attached the picture below
The BER analyzer chooses the best instant with the widest eye opening as the decision instant to calculate max. Q-factor. Now if you define any other instant, your Q-factor would not be as much, so you have to increase the power as a penalty to get the same Q-factor as the max. Q-factor.
hi alitsu,
but if I use “max q factor” in a 16 channel wdm(I have attached it below) system I get maximum q factor of 4.9 but if in case of “penalty:Q factor from Min.BER at user defined decision instant(dB)” I get maximum q factor of 33 .what can I use to define the quality of transmission
i have started simulating your file, but it seems it will take a lot of time to finish. Can you please attach a screen shot of the result with the obtained value (the one you have been referring to and you have shown in the topic main post attached image)?
The y-axis shows the power penalty in dB, and not Q-factor. It means that, for example, for the transmission line of 140 km, you need to use 60dB more power I order to maintain the same max. Q-factor (which is about 4.8 according to your Q-factor graph) for the user defined decision instant.
I wanted to ask whether this is the system you had formerly asked for suggestions for performance improvement. I once used DCF and once reduced the WDM laser linewidth to 0.1 MHz, which is acceptable for low power CW lasers, but neither of these methods made a remarkable change in the Q-factor. However, I suggest that you go with laser linewidth reduction and see if that helps.
I have read many research paper in those paper q-factor is always more than 10 but when I do the same simulation in optisystem q-factor is always less than 6.i have attached some papers and simulation files if u have time please point out my error in simulation
