      For optical communication the BER should be lower than 10e-9, which is a Q of 6. In other words, we consider a system with BER lower than 10e-9 (Q of 6) an error free system.

      What is the formula between BER and Q?

      I have attached three pictures taken from the component help of the BER Analyzer. You can access this by right clicking on the component and choosing Component Properties. Then click on Help and scroll down to the Technical Background section. The explanation of the Q factor calculation is found there.
