Dear Nur Syafiqah,
typically, BPF is used to filter part of the signal centered at the BFP’s center frequency with a specific bandwidth. in Optical communication, it is used for selecting part of the transmitted optical signal or filter the ASE noise from it. OptiSystem has a wide selection of BPFs, which you may choose. they differs in their shape which affected the filtered signal.

Dear Aseel,
The issue could be related to the setting of the operating wavelength range of the Dual Port WDM Analyzer.
Please set the proper range and make the measurements.

Dear Arya,
You need to check the axis that shows the amplitude of the eye and make sure that you compare same units.
If the issue still not resolved, please email me your project as Zip file to ahmad.atieh@optiwave.com and I’ll check and provide feedback.

Dear Miroslav,
all component can be used for free-space optic communication. Th LiFi component is best suited for LiFi, how it is limited to ON-OFF DD system. The other three components are flexible to use any modulation and detection. You may use the LOS component for short distances, FSO for ground level transmission and OWC for ground to satellite transmission. Please check the parameters of each component for your needs.

Ahmad

Hello Magdy,
You may use the sweep feature of the laser to tune it with the desired range. Please check the introductory examples at C:\Users\USER NAME\Documents\OptiSystem 21.0 Samples\Introductory tutorials\ in OptiSystem Example library for guidance.

Hello,
typically, the LO is CW laser at same wavelength like the TX laser.

Hello,
there is a feature in OptiSystem where you can create images for eye diagrams or any other plots of the visualizers. You need to access the project browser, then select the desired image and right click on it to create the frames or video. you may define a parameter in the Matlab component and sweep that parameter.
please let me know if the issue is not resolved through email (ahmad.atieh@optiwave.com).

Hello,
Please email me (ahmad.atieh@optiwave.com) your project as Zip file as you can’t load OptiSystem projects directly to the forum.

Hello,
please check the example (RA 100nm bandwidth flatten gain AvgPower.osd) in OptiSystem Example Library at C:\Users\USER NAME\Documents\OptiSystem 21.0 Samples\Optical amplifiers\Raman amplifiers\ for guidance. It is a backward pumping. Don’t forget to load the Raman gain profile file when you calculate the project.

Dear Ayten,
please check the datasheet of the TDF as it describes the rate equations used for calculating the gain and ASE.
you may access the datasheet using the Help in the component properties window.

Hello,
It is difficult to debug the project because the project is not fully displayed.
Could you please email me (ahmad.atieh@optiwave.com) your project as Zip file to check the cause of the issue?
