In the picture, only source and fiber, two optical oscilloscopes, the resluts from two OOSC are in the same timing, even the fiber have 50km, so the fiber dont introduce any time delay, the resluts is right? 

By the way, the fiber need turn off the " Nonlinearities" then can be run in "sample mode", will this decrease the reliability of the simulation?

Hi pengzheng97,

 

Thank you for the post. Yes the fiber model doesn't include the time delay in itself, because most of the time people care more about the channel behaviour than the time trnamission in the fiber. And with a long fiber if we include the delay then the simulation time will be very long.

If the nonlinearity if turned off then the model only simulates the linear dispersions in fiber model. The model will still be accurate but not include the nonlinear effects. You can use the nonlinear model in block mode.

thanks for your explanation, got it !
