Dear sir,
I am using the Licence version of Optysystem 15.1. I have tried a lot to get the BER value by using BER analyzes but didn’t a success when using advanced modulation technique. In sample files also all examples have been given by using BERT. would you please guide me what modification is required for getting a result in BER analyzer.
As you said Typically for 10G system the min BER is 1E-12. However, if you use FEC or ultra FEC you could tolerate 1E-3 or 1E-2, respectively. can you please explain how.

Dear sir,
As we know for a good optical system the BER value will be accepted below 10^-9,similarly what is the corresponding value of BER test set so that it can be accepted as good communication system? and how to get the Q-factor value from BER test set.

Hallo everybody,I am also finding the same problem in BER analyser.eventhough eye diagram is comming but the values of q factor and ber rate is 0 and 1.so please help,anyone experts
