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.

dear colleges,
I am trying to simulate QAM4-OFDM WDM PON system.
BER tester is utilized in the OFDM part .
the system shows the EVM but always it shows BER=zero and it doesn’t realistic.
the input signals are CW 193.1 THz 193.16, 193.2, 193.26 THz, line width is 0.1 MHz.
the system speed is 10 Gb/s. is the line width of the CW laser source has the effect on the BER appearance? or what?
your help is highly appreciated.
Hello,
You may have some EVM value while the BER is zero. You may check the SER, it should be zero too.
Regards,
Ahmad
Yes SER is zero also whenever BER is zero.
1- what is the best bitrate to configure and evaluate the OFDM QAM4 system based on?
because when I increase the bitrate the BER is increasing with SMF distance (take the symbol rate half of the bitrate because I am using QAM 4)
2- if I took the one span (10km SMF, 2km DCF) should I include the length of the DCF in the OFDM demodulator or just the SMF?
if NO, then if I increase the span to 20 the DCF will be 40km is it ok to not include its length?!
Should I put a value in the OFDM POWER in the OFDM modulator?
Yes, you need to specify the power in the OFDM Modulator. This will affect the transmission characteristics.
Regards,
