FSO

[Md. Asraful Sekh]

Sir,
Could you please explain how optisystem can be used for designing multi beam free space optics communication heads?

[Damian Marek]

Multiple OWC channels can be simulated by splitting a modulated signal into several branches (power splitter) and attaching each branch to an OWC. A power combiner can be used at the receiver to combine the separate channels.

The enclosed paper describes a model that could be implemented in OptiSystem.

@ Asraful,

Do you mean a Wavelength Division Multiplexed FSO System or what Damien proposed as a solution?

@Damien,

I do not see any paper attached to your message. Could you please check it again?

Additionally, what is the difference between the OWC and FSO block? They both look the same having almost the same parameters.

Hi Ahmad,

The attachment appears for me (it also works when I am logged out). Let me know if you are still having trouble seeing the attachment.

The Free Space Optical Links post gives you a brief description. They are basically two different, yet similar models, that are optimized for short and long free space channels. For further info, take a look at the component help file (double-click the component in the layout and then choose the Help button), this will give you details on how each are modeled.

Hi Damien,

I can see the attachment now. Thanks

Hi Damien & Mustafa,
i have got the attached paper, it will be useful.
i will get back to you after some times if i have any query or help from your side.
thanks,

Hi Md. Asraful Sekh,
i agree to the points of Damian Marek sir that simulation of Multiple OWC channels can be done by splitting a modulated signal into several branches (power splitter) and attaching each branch to an OWC.
I want to share some links:
