Two joined step index fibers are perfectly aligned. What is the coupling loss of numerical aperture are NAR= 0.26 for emitting fiber?

Two joined step index fibers are perfectly aligned. What is the coupling loss of numerical aperture are NAR= 0.26 for emitting fiber? Correct Answer -0.010 dB

Coupling loss for two joined step index fibers is given by LF(NA) = -10 log (NAR/NAE)2 Where LF = coupling loss NAR = Numerical aperture of receiving fiber NAE = Numerical aperture of emitting fiber.
