Fiber Installation and Activation graded A+ already passed 2023What is the Fiber-optic cable term for optical transport that is restricted to one path (mode) for light propagation through the core of an optical fiber? Single Mode Fiber A type of optical fiber with large core diameters which allow multiple modes, or paths, upon which the optical signal travels is known as what? Multi - Mode Fiber In fiber-optic terminology, what is "window" ? Refers to a center optical wavelength, as well as a range of wavelengths on either side of the center wavelength What are the four standard optical windows? 850 nm, 1,300 nm, 1,550 nm, and 1,625 nm. What window is exclusively used for multimode fiber? 850 nm What is an Erbium-doped fiber amplifier (EDFA)? An optical amplifier that uses active erbium-doped fiber and a pump source (laser) to boost or amplify the optical signal? What are the three basic components of all fiber-optic communications networks? (1) an optical transmitter with a light source; (2) the optical fiber (3) an optical receiver with a photodetector. What characteristic of a fiber-optic cable enhances the security of signals being transported in the network? Fiber optics are typically made of glass which is a dielectric material which is basically immune to EMI and RFI What telecommunication standard designation encompasses all things voice, video, and data? ITU Telecommunications Standardization Sector ITU-T Single -mode fiber-optic cable is optimized to transport which wavelengths? 1310 nm & 1550 nm An optical fiber consists of what three basic parts? Core, Cladding, and Coating What does the spectral width of a laser or Light Emitting Diode (LED) define? A measurement for the band of wavelengths over which a laser light source emits its energy, generally measured in nanometers (Nm) between the half power points of an optical light sources maximum amplitude at the center frequency Full Width Half Maximum (FWHM) Which type of laser is ideal for analog, high speed digital, and optical multiplexing networks because of its high SNR (signal to noise ratio) and small spectral widths? Distributed Feed Back (DFB) laser
