# Light-pipe acceptance screening
# Scope: Straight light-pipe transmission using supplied coupling and loss-per-length; bends omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

inputPower = 10 mW
coupling = 0.8
attenuation = 0.2 m^-1
length = 1 m

outputPower := inputPower*coupling*exp(-attenuation*length) [mW]

check output power target: outputPower >= 5 mW

scenario alternative: inputPower = 8 mW
