Fiber Optics Exam Questions and Answers 2024 Mode Field Diameter - Answer ✔️✔️-The diameter of the light emerging from the end of the fiber is also termed... core, cladding, and prime coating - Answer ✔️✔️-The basic construction of fiber is: zig-zag - Answer ✔️✔️-A multimode step -index fiber transmits light down the fiber in what pattern? Single -Mode - Answer ✔️✔️-This type of fiber has only one mode for the ligh t to travel down. glass core and plastic cladding - Answer ✔️✔️-Plastic -clad silica cables have what kind of construction? material dispersion - Answer ✔️✔️-different wavelengths travel at different speeds along the same path 5-10 micrometers - Answer ✔️✔️-the typical core diameter range for single -mode fiber optic cables 125 micrometers - Answer ✔️✔️-typically the cladding of a fiber, regardless of its core size is what diameter? waveguide dispersion - Answer ✔️✔️-a singe wavelength travels at different sp eeds in different materials .50 km - Answer ✔️✔️-if you are using a fiber optic cable that is designed to transmit 600 MHz for a distance of .75 km, how far could an 800 MHz signal travel on the same cable microbend loss - Answer ✔️✔️-little bumps in the c ore at the junction of the core and cladding are called? frequency goes up - Answer ✔️✔️-distance goes down attenuation - Answer ✔️✔️-dB/Km is how ________ of optical power is measured numerical aperature - Answer ✔️✔️-The _______ ________ of the optical s ource, fiber, and optical receiver must match for best transmission tight buffer - Answer ✔️✔️-allows a lower tensile strength but a higher impact and crush resistance plenum -duty fiber - Answer ✔️✔️-type fiber used if you are installing it in a return air vent / space in a building strength members - Answer ✔️✔️-the part of the fiber optic cable that allows you to pull it when you are installing it MHz per Km - Answer ✔️✔️-many manufacturers specify bandwidth -length in ______ instead of specifying dispersion in the modal offerings 300 dB/Km - Answer ✔️✔️-plastic fiber would have an attenuation in the range of shorter wavelength - Answer ✔️✔️-rayleigh scattering decreases with ________ light waves Graded Index Fiber - Answer ✔️✔️-fiber optic cable constructed by layers of increasing index of refraction core material single mode fiber - Answer ✔️✔️-when using ________ fiber optic cable you must worry ab out matching the cable to the frequency of the light you are transmitting more than other types of cable single mode fiber - Answer ✔️✔️-has smaller core so it is particular about light frequency modal dispersion - Answer ✔️✔️-doesn't exist in single mode fiber (zig -zag flatlines out) must go slower but greater distance - Answer ✔️✔️-in a single mode fiber optic cable, you can send a 1300nm wavelength faster but for a shorter distance, what would be the effect if you would send a 1500nm wavelength down this same cable? blue - Answer ✔️✔️-fiber number 1 orange - Answer ✔️✔️-fiber number 2 green - Answer ✔️✔️-fiber number 3 brown - Answer ✔️✔️-fiber number 4 slate - Answer ✔️✔️-fiber numer 5 white - Answer ✔️✔️-fiber number 6 red - Answer ✔️✔️-fiber number 7 black - Answer ✔️✔️-fiber number 8 yellow - Answer ✔️✔️-fiber number 9 violet - Answer ✔️✔️-fiber number 10 rose - Answer ✔️✔️-fiber number 11 aqua - Answer ✔️✔️-fiber number 12
