Global parameter window

[Ashu vermaParticipant]

Since i am new to optisystem software,i wanted to know about global parameter window
1.) how to select sample
2) what is time window

[Abhishek ShramaParticipant]

Hi Sam sung, welcome to optisystem
you can check the optsystem documents for the information about global parameter window
optisystem>documents>global parameter

1) You can select any no. of samples 16,32,64,128,but as you increase the sample per bit it will increase the accuracy and also simulation time.
2)you can calculate time window as sequence length/bit rate ,it calculates the time of your one sequence.

I am designing a WDM system but no eye diagram appeared on BER analyzer.Can you please attach any sample system??????

How to set the bandwidth of MUX and DEMUX? every time i am changing the BW ,results gets changed

[Abhishek ShramaParticipant]

You can set the BW= 2*bit rate
e.g
Bit rate =10Gbps
then B.w of Mux/Demux =20 GHz

[Ashu vermaParticipant]

Thank you,now i get better results.In some systems they take BW four times.Does it increase system effciency.
