$F An Optical Fibre Has A Core With A Complex Refractive Index Equal To 1 6 J2 X 10 11 It Is Illuminated With Light 1$: F An Optical Fibre Has A Core With A Complex Refractive Index Equal To 1 6 J2 X 10 11 It Is Illuminated With Light 1 (17.54 KiB) Viewed 53 times

f) An optical fibre has a core with a complex refractive index equal to (1.6 - j2 x 10-11). It is illuminated with light at a wavelength of 850 nm. Calculate the distance at which the optical power within the fibre has decreased to 1% of its input value.
