Thank you so much Eng. Tangi; Please, in this youtube channel you explain in Cailabs Academy - Season #2 with only 3 videos! where is Season #1? Please, if you could provide to us a complete course (with English subtitles as you used in Season #2) regarding optical fiber communication systems and free space optics (FSO); You explanation is very good, animations are inspired. Please, if you could also include the mathematical model for FSO, also, I have difficulties in understanding the concepts if advanced topics such as: orbital angular momentum, mode division multiplexing, multicore fiber principles, optical modulations, fiber nonlinearities such as SBS, FWM...and so on. I'll so thankful to you. All the best to you :)
