Unformatted text preview: The fiber’s loss is 4 dB/km. Compute the power in the fiber at 1 m, 1 km, and 10 km. Repeat this problem if the fiber now has NA = 0.5 and a loss of 500 dB/km. Problem 4: Two multimode fibers are being connected with an air gap between them. The air gap is now filled with an index-matching fluid that is not perfect: It has a refractive index of 1.4, while the fiber core has an index of 1.48. Compute the reflected-power level (in dB) with respect to the incident-power level. Include the two interfaces (fiber-to-matching fluid and matching-fluid-to-fiber)....
