Pseudo-Random Bit Sequence Generator simulation error

[feng gangParticipant]

I simulate sample named FE-OCDMA 3 Users.osd in ..\OptiSystem 12 Samples\Access systems\FE-OCDMA 3 Users.osd。 report a error as
“CIDF Scheduler: error occurred while calculating, component Pseudo-Random Bit Sequence Generator Error in Pseudo-Random Bit Sequence Generator: The sequence length, or the product between the parameter bit rate and global time window is zero, Calculation failed!”
please help me! thanks in advance

Hi,

Some of the default global parameters might have been changed accidentally. To re-install the sample files, go to:

C:\Program Files\Optiwave Software\OptiSystem 12\

and run the OptiSystem_Samples.exe executable. This should return your sample files to a functioning state.

Dear Feng Gang,
I think the problem in this sample is the FBG connections. You can drop an email to me at: dr.hamza.alkhafaji@gmail.com
