3 Questions
What is the formula to calculate coupling loss in a fiber coupler?
Coupling loss (in dB) = -10 * log10 (P3 / P0)
How do you calculate insertion loss in a fiber coupler?
Insertion loss (in dB) = -10 * log10 (P1 / P0)
What is the formula to calculate excess loss in a fiber coupler?
Excess loss (in dB) = -10 * log10 ((P1 + P2) / P0), assuming the coupler is ideal
