Hello,
I recommend using the FBG component in OptiSystem. There are couple of examples on FP lasers in OptiSystem example library.
If you need more information please email me at ahmad.atieh@optiwave.com

Hello Gabriel,
there is no example in OptiSystem on BOTDA.
to lean how to use the Matlab component, please check the files in the folder located at C:\Users\USER NAME\Documents\OptiSystem 21.1 Samples\Software interworking\MATLAB co-simulation\.

Hello,
One thing to check is the input and output ports’ connection to the analyzer.
You may email me the project as Zip file to check it. My email is ahmad.atieh@optiwave.com. You may get negative effective noise figure in some cases that incorporate Raman amplification. I don’t expect to get it in EDFA/TDFA.

Hello Feng,
you should be able to build the LFM-based Phi-OTDR in OptiSystem and you could use the Matlab and/or python components to complement any missing component.

Hello,
Please check the Fiber Bragg Grating component. You should be able to use the built in Apodization functions or load your own profile. That can be set in the component properties window under the Apodization tab. You may access the component datasheet using the Help button, where you would find the file structure.
If you still have question, email me at ahmad.atieh@optiwave.com and let me know the version of OptiSystem that you use. Also, let me know your institution name.

Ahmad

Dear Debarun,
the issue is related to loading the Raman gain profile. the files can be found in the example library located at C:\Users\USER NAME\Documents\OptiSystem 21.0 Samples\Optical amplifiers\Raman amplifiers\.
If the problem persist, email me at ahmad.atieh@optiwave.com and let me know the example that you are experiencing the problem with. Let me know also your institution and the version of OptiSystem that you use.

Dear Fengyuan,
You may the bidirectional fiber component and other needed components in OptiSystem component Library to build an OFDR system.

Dear Fengyuan,
The current Phi-OTDR component in OptiSystem is a standalone component, which can be designed to simulate multiple vibrations. We are working to make this component integratable with other components.

Dear Saad,
the issue in the example is related to the relationship between the bit rate and baud rate in the project layout parameters. You can set the bit rate to 60Mbps, then the symbol rate should be set to 10Msymbol/s. You need to pay attention to the quadrature center frequency in relation to the baud rate.

Hello,
The Phi-OTDR component allows you to load experimental data and verify the simulation.
You may email me at ahmad.atieh@optiwave.com to discuss further.
