Compute the fiber nonlinear coefficient of a parametric optical amplifier having parametric peak gain of 63.6 dB, signal power of 1.6W, length 520.

Compute the fiber nonlinear coefficient of a parametric optical amplifier having parametric peak gain of 63.6 dB, signal power of 1.6W, length 520. Correct Answer 9.61×10-3 W-1km-1

The fiber nonlinear coefficient can be found by γ = Gp(dB)-log10(0.25)/Ppl×L × 1/10log10(2.718)2 = 63.6+6/1.6×1.6×520×1/8.7 = 9.61×10-3 W-1km-1.
