Hi All

As I simulate SMF 28 ultra fiber Return Loss, use NSC mode to simulate this item.

fiber(source DLL in the fiber core) + polish angle 8degrees + Alens + Mirror.

  Based on fiber NA 0.094 to set cladding and core, but seems not mach. How to set the fiber cladding and fiber core index/ size ?

Based on fiber w0 =10.4um/2, but it not TIR in the fiber core. How to set Gussian source w0+position to match with fiber set?
