Hi Ravil,

The mode filed diameter depends on fiber parameters and the operating wavelength. Usually it is just above the core diameter in the case of SMF, So the MFD is in the micrometer range. It can be find out using one equation (w/a)=0.65+(1.619/v^1.5)+(2.879/v^6). This equation may be valid to the fundamental mode of MMF.

My question is what is the MFD of the fundamental mode of OM2 fiber at 1300nm?

Do you know the approximate range of MFD of the fundamental mode of SI-MMFand GI-MMF at 1500nm. I just want to check my answers

Dear sir,

I need to launch signal to an MMF from an SMF with and without offset. Can i directly connect the output of mach-zender modulater output waveform to spatial connector. When i did like this, it shows error. Also i need to see the modes of the multimode fiber. Which component i need to use forr this purpose? I am attaching the file with this.

I think in order to simulate waveguide or fiber you need to install the software related to system or fiber.
