GPON Fiber optic cabling simulation

I don’t know whether this is acutally possible.

I’d like to use Fritzing to simulate fiber optic cabling using PLC splitters.

to illustrate:
my laser light source has +3dB
1km single mode fiber has a loss of 1dB
a PLC splitter splits the light into multiple beams (1:2 / 1:4 / 1:8 / 1:16 — 1/128), each type has different loss. A 1:4 splitter for example has a loss of 7dB

I’d like to be able to see the current light strength at every point I click

[ OLS ] ----- (+3 dB) --------- [ 1km cable ] ----- (+2 dB) ------- [ PLC 1:4]
------ ( -5 dB) -------
------ ( -5 dB) -------
------ ( -5 dB) -------------- [ 1km cable ] ----- (-6 dB) ------- [ 1km cable ] ----- (-7 dB) -----
------ ( -5 dB) -------

Is Fritzing the right software to do such a simulation?

Thanks
