      Hi,
      The Q value obtained in BER Analyzer block is in dB or linear?
      In OptSim Q is in both dB and linear how can i compare Q values obtained from OptiSystem with same corresponding layout in OptSim software.

      The calculated Q-factor values in OptiSystem are linear.

      Hello Siva rama krishna, Tech Support is right in saying that the Q-values obtained fro the optisystem are linear. If you are interested in taking the Q-values in dB then kindly apply the log units and convert them into dB.

      Hi Siva Rama Krishna,

      As far as the calculated Q-factor values in OptiSystem are concerned,they are linear.. But i really dont know how to compare Q values obtained from OptiSystem with same corresponding layout in OptSim software…

      Regards

      Hi fayiqa ma’m
      In physics and engineering the quality factor or Q factor is a dimensionless parameter. The higher the Q, the narrower and ‘sharper’ the peak is. In many design we plot Q-factor and min. BER against input power in dbm.
