Fiber Installation and Activation NEW Exam Questions &
Answers Latest Update
Which of the following is true about fiber-optic cable? Choose all that apply. - ✔✔✔ - A 3/4-inch round
fiber-optic cable can be manufactured with up to 864 optical fibers, which weigh approximately 130
pounds per kilometer.
Fiber-optic cable is affected less by moisture and thermal conditions than is copper.
Because the optical fiber is made of dielectric material, the cable does not carry electrical current,
radiate energy, or produce heat or sparks.
What is the wavelength of a 150 MHz carrier wave? Use the speed of light measured in meters per
second to finish this equation: 300 x 106 divided by 150 x 106. - ✔✔✔ - 2 meters.
How much do you know about the elements of a fiber-optic communications network? - ✔✔✔ - The
encoder portion of the data encoder/modulator codes analog signals for conversion into digital signals
and the modulator portion transforms the digital signal into the appropriate modulation format.
During the process of converting an electrical signal to an optical signal, the electrical interface
provides one or a combination of any electrical protocols to the data encoder/modulator.
The modulation signal is applied to the light source which could be either a light emitting diode (LED) or
laser diode.
What characteristic of fiber-optic cable enhances the security of signals being transported in the
network? - ✔✔✔ - There is no EMI or RFI radiation, or other detectable energy, radiating from the
cable, so the transport of signal through fiber-optic cable is very secure.
Which telecommunications standard designation encompasses all things video, voice, and data? -
✔✔✔ - The ITU Telecommunication Standardization Sector (ITU-T) designation encompasses all things
video, voice, and data. The ITU-T G-series recommendations address optical system design and
engineering considerations.
