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.

here i upload 16-qam CO-OFDM system. but i tried to put 64-qam and 256-qam. i did not produce significant result. pls provide useful post to me.
thanking you all
hi zulkarnain,
please read the query of karthikan ravi, he has attached .osd file and he he needs help in that regards, i think he is well aware of theoretical aspects of the QAM and OFDM.
i have not acess to software this time but i will try to fiqure that soon about the problem in your .osd file
hello ravi,
well i can’t access your osd file right now but could you please tell that do you vary any of the parameters of any component, the symbol rate, bandwidth of the filters or any other component while changing your modulation schemes???
I would want you to look at the link that i am posting below. You might find this link helpful.
Hi aasif..
Actually i have access to software only during lab hours. That is why i uploaded some theoretical posts which i find useful for the topic.
Hopefully i will look into this tommorrow.
regards
Hi ravi,
To make 64 and 256 QAM OFDM modulation first you have take 6 bits(2^6=64) and 8 bits(2^8=256) in QAM modulator and then proceed further and make necessary changes to have expected results.
hi all,
ranjeet is right. You need take to first take necessary parameters into consideration like number of bits in modulator etc before moving from 16-QAM to 64-QAM or 256- QAM. There are few variation in parameters required. I will attach an osd file which would definitely give u an idea hw to proceed and make necessary changes in ur network.
thanks and regards
hi every one,
thanks for the reply. i tried to change the parameter like 6 and 8 bit per symbol at the QAM modulator and demodulator. that file 16QAM modulator MIN BER value quite well at the datarate upto 40Gb/s the distance maximum 100km with 10GHz carrier frequency. but 64 & 256QAM MIN BER cant found margin value.
hi………. everyone, if anyone idea about 64&256 qam modulation parameter. i attached already, i need suitable reply for that, i did not produce significant result. pls provide useful post to me.
thanking you all
Can anyone help with the setting of 64QAM? how can I calculate the BER from the 46QAM system? I try the test BER set but still did not get the results.
