Unformatted text preview: intermodal dispersion to D=10 ns/km. What is the numerical aperture of this fiber? Use a group index of refraction of 1.45. 4. Problem 2.14 5. Sketch the maximum distance of propagation (i.e. the loss and dispersion limits) for the first 4 major fiber optic revolutions: 1. GaAs lasers, multimode fiber, multimode lasers 2. 1.3 micron InGaAsP lasers, multimode fiber 3. 1.3 micron InGaAsP lasers, single mode fiber 4. 1.5 micron InGaAsP lasers, single mode dispersion compensated fiber State the assumptions you make about the spectral width of the sources....
