Unformatted text preview: index fiber. Compute the coupling efficiency for both cases for the given operating parameters: a) Transmissivity of the medium 0.8 b)Refractive index of the medium between source and fiber 1.2 c) Radius of the fiber core: 0.9 x y − d) Fiber numerical aperture 0.45 Problem 4: When an LDA source operating at 30 C ° is forward biased with 2 V it generates 50 mA of forward current. If the source is to operate at 45 ° , calculate the mean time between failures (MTBF)....
