OTDM

[SAHIL SINGHParticipant]

in the hybrid networks or simple ioptical time divison multiplexing.

there we use single wavlength and modulate it with different data, how to provide the to them so that it will lead to faithfull time divison multiplexing.
what should be delay , is there any pattern or formulla for that.

hello sahil singh…….
In optical time-division multiplexing (OTDM) systems, several optical signal modulated at the bit rate B using the same carrier frequency are multiplexed optically to form a composite optical signal at a bit rate NB, where N is the number of multiplexed optical channels.

Hi tanveer,
Thanks for such an informative answer..

you are welcome sahil…

Hello sahil,
First of all i would like you to tell us what are you exactly designing and as far as theoretical part and simple simulation set ups are concerned you can check the optiwave examples in the optisystem samples folder. You can also follow the link to get an idea how a basic OTDM system is implemented and other required information.

Hi aabid baba…
Thank you for sharing such an informative link… Infact i was checking the examples in the optisystem samples folder.. I am implementing a basic OTDM system. So your link was very helpful..

hope these sample file will help you in regard of how to provovide the delay for pulse interleaving for making proper optical time division multiplexing,

[umer syedParticipant]

hi all,
the sample files uploaded by asif bashir dar sir, has every thing which sahil singh needs for his otdm design.

it looks there in the .osd files that the formaula for the time delay of different pulses from single wavelength is given.
i appreciate asif for uploading the sample files

with regards

[aasif bashir darParticipant]

you are welcome wmar

[SAHIL SINGHParticipant]

Hello tanveer and asif

Indeed the file uploaded by asif bashir has a lot of information about the otdm design…

Thank you asif for your efforts and valuable time…

Highly appreciated

[TanveerParticipant]

you are welcome sahil singh…
hope you have got the problem addressed in the forum…

Hi Jojo Mathew

I do not understand what you have written Awaiting moderation ?

Please specify what does it mean,so that we can be of any help to you..

Hi Sahil,
it suggests that jojo mathew has just joined is his posts and replies are in monitoring mode. It is an admin thing and all moderation are must for allowing someone to join. You can think of it as verification scene. That’s the reason you are not able to see his posts.
