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..
OptiOmega is a collection of products specialized for photonic integrated circuit simulation. It automates the design flow for
generating compact models from device level simulations. The software package includes two solvers that can be used via
Python scripting: Vector Finite Difference (VFD) Mode Solver and Finite Difference Time Domain (FDTD) Electromagnetic Solvers.

Hi,
I am designing Duobinary modulation over SMF fiber and i need some clarifications
1) can we replace precoder and adder circuit with Bessel electrical low pass filter.If possible provide circuit diagram and filter specification i need.
2) In modified duobinary can i replace precoder and sub-tractor circuit with high pass filter? Please provide details.
3) Before detector circuit(after transmitted with fiber) can i user Bandpass Bessel filter. Please provide its importance and parameter specifications.
4)Duobinary modulation using symmetrical structure.
Advance in Thanks

Thank you for your query. Unfortunately we are not very familiar with the techniques you describe below. We did however find a paper (attached) which discusses using FIR filters in combination with a low pass filter to generate duo-binary signals. Possibly this will help you with your design query.
Sorry for not being able to respond in greater detail.
We hope the enclosed information helps!
