Hello everyone, I have a question about measuring Q factor.
Could someone please tell me How can I measure Q factor for PAM-4 or QAM-16 by using the BER analyzer only not using BERT? I have Optisystem 19.
Thank you very much

Thank you Dr Ahmed. I sent you the mail
Thank you dr ahmed but the only problem I need to search for fiber optics so I need to focus on laser communication for high data rate application so i need to select a topic related to the previous field
you can model this type of polymer fiber using optifiber and feed the results into optisystem
how to use the parameter thermal noise is 1e-22 w/hz in sensetivity calculation
there is link inside the alistu’s link is unavialable
dr Alistu THE link is unavilable
but mr aabid baba the parameters you have mentioned doesn’t exit in pin photo detector component layout
Thank you
ok
dr alistu :but i have a paper ,the author has done experiment with laser source with o/p power 6.8 dbm and with linewidth 0.4 nm at wavelength 645 nm using plastic fiber with length 200 m.
i need your help to know how can i enter the 0.4 nm at the linewidth of the laser source component in optisystem?
What do you think about the appropriate value for the linewidth
if i have cw laser source at wavelength 1550 nm with linewidth 0.4 nm ,how can i enter the value of this linewidth in CW laser component??
the linewidth in optisystem is given in MHZ??
please help me
