8. Which type of fiber is preferred for use in modern computer networks? a. Multimode b. Polarized mode c. Single-mode d. All of these answers are correct 9. What is the two deep rule relative to optical networking? a. This means the horizontal distribution to the work floor can only have two 8P8C connections. b. This means the horizontal distribution to the work floor can only have two ST connections to the fiber patch panel. c. This is no longer an issue with high-speed, single-mode fiber and wave division multiplexing equipment. d. This means that a building should have only the main distribution and the intermediate distribution that feeds the horizontal distribution to the work area. 10. The broadening of a pulse due to the different path lengths taken through the fiber by different modes is called what? a. Chromatic dispersion b. Polarization mode dispersion c. Modal dispersion d. Diffusion 11. What are the commonly used wavelengths in fiber optic systems? 12. Define pulse dispersion. 13. What are the typical core/cladding sizes in microns) for multimode fiber? 14. What mechanism does fiber optic cable use to transfer information? Explain
