FIBER OPTIC CABLE INSTALLATION, SPLICING, AND MAINTENANCE TEST LATEST 2023 -2024 REAL EXAM QUESTIONS AND CORRECT ANSWERS|ALREADY GRADED A+ Fiber Optics - ANSWER - The technique of transmitting information through flexible glass or plastic fibers using light waves. The 3 components of a basic fiber optic system - ANSWER - Transmitter, physical plant, receiver The physical plant component of a basic fiber optic system consist of: - ANSWER - The cable, connectors, splices, panel, and closures Part of the receiver conve rts the optical signal back into an electrical signal. - ANSWER - The detector a positive intrinsic negative (PIN) photodiode or an avalanche photodiode (APD). Two types of light in the fiber optic equipment. - ANSWER - Light Emitting Diode (LED) and Light Amplification by Stimulated Emissions of Radiation. The speed of light through the air. - ANSWER - 186,000 miles per second The speed of light through water - ANSWER - 140,000 miles per second The speed of light through glass - ANSWER - 124,000 miles per s econd The wavelength, frequency, and speed of vibrating________ are all related to each other. - ANSWER - Waveform The unit of measurement for wavelength - ANSWER - Nanometer (nm) As frequency increases the wavelength becomes __________; as frequency decr eases the wavelength becomes _________. - ANSWER - Shorter; longer A particle of light is called a ____________. - ANSWER - Photon True or False Photons have no mad and will pass through each other. - ANSWER - True Light is electromagnetic energy with a _______________ frequency and __________ wavelength than radio waves. - ANSWER - Higher; shorter Three common wavelength Windows used for communications through optical fibers. - ANSWER - 850nm, 1300nm, 1550nm Refract ion - ANSWER - The bending of light as it passes from one transparent material into another transparent material of different destinies. Three parts of an optical fiber - ANSWER - Core, cladding buffer The most cladding diameter for glass fiber - ANSWER - 8 microns and 10 microns The typical diameter for loose tube buffer coated fibers - ANSWER - 250 microns Where cables containing loose tube buffered fibers are typically used - ANSWER - Outdoors Typical diameter for tight tube buffer coated fibers - ANSWE R- 900 microns Optical Fiber works because of this principle - ANSWER - Total Internal Inflection Determines the lig ht-gathering ability of a fiber - ANSWER - Cone of acceptance The purpose of "normal" in an optical fiber - ANSWER - The purpose of the nor mal is provide a reference point from measuring angles that develop as a result of both refraction and reflection which occurs as light propagates through fiber. The angle at which light rays reflect or bounce back from the surface of an object - ANSWER - The a ngle of r eflection The angle at which light Ray strikes the end of the fiber or the angle at which the light Ray strikes the cladding surface from within the fib er core - ANSWER - The a ngle of incidence The refractive index is the ratio of the speed of light in a ____________ to its speed in a ______________. - ANSWER - Vacuum; Medium The specified range that light must enter a fiber in order to maintain the _____________ angle is the cone of acceptance, also called the acceptance cone. - ANSWER - Critical Angle When the angles of ________ and _________ are equal, a whole beam of light is reflected to provide internal r eflection. - ANSWER - Incide nce, reflection
