dear dhiwan can get a sample how to use DSP block

[lavanya krishnanParticipant]

thanks dhiman for ur help

[lavanya krishnanParticipant]

where can I find DSp

[lavanya krishnanParticipant]

thanks. but I need to know is there any device(block) which can reduce the isi in optisystem?

[lavanya krishnanParticipant]

I have read many research paper in those paper q-factor is always more than 10 but when I do the same simulation in optisystem q-factor is always less than 6.i have attached some papers and simulation files if u have time please point out my error in simulation

thanks but in case of q-factor it is very low why? as far as I know acceptable q-factor is 6-9?

hi alitsu,
but if I use “max q factor” in a 16 channel wdm(I have attached it below) system I get maximum q factor of 4.9 but if in case of “penalty:Q factor from Min.BER at user defined decision instant(dB)” I get maximum q factor of 33 .what can I use to define the quality of transmission

I tried to compare the performance of edfa and hoa(edfa+raman) in that I got high q-factor for edfa than hoa(edfa+raman)
below I have attached all files

you can open that file only if u use optisystem 9 or later versions u cant open it in optisystem 7 version

[lavanya krishnanParticipant]

thanks alitsu

[lavanya krishnanParticipant]

I figured out what was the problem no more help needed anyway thank guys

[lavanya krishnanParticipant]

hello sasha ,
may I know how to get curve attenuation vs wavelength? what optical visualizer we have to use

[lavanya krishnanParticipant]

thanks sasha

[lavanya krishnanParticipant]

hi sasha,
thanks for ur help
in my simulation I can not obtain graph similar to ur one if u don’t mind can u pls upload ur simulation file pls
