      Attached is a simple 4 channel CWDM system using the optical transmitter component and the 3R regenerator. The simulation works as expected with the BER of each channel changing with changing variables such as length, dispersion, wavelength etc.

      My question is, why does the BER not change if I run the simulation a number of times in a row. (with no changes in the component parameters)
      I have run a similar simulation using the CW laser and MZ modulator etc and each time I run the simulation I get different results for the BER, as I had expected due to the random nature of noise.

      Does anybody have any ideas?
