With underground plant construction, - ✔✔The fiber-optic and coaxial cables are often
|| || || || || || || || || || || ||
placed underground with other utility lines to jointly share construction costs.
|| || || || || || || || || ||
Standby power supplies - ✔✔Continue providing an output voltage even during a utility
|| || || || || || || || || || || || ||

two or more individual optical fibers are required for each optical node location.
|| || || || || || || || || || || ||
, 2
RF trunk amplifiers - ✔✔Have attenuator pads, equalizers, and diplex filters that control
|| || || || || || || || || || || || ||
and route the RF signals.
|| || || ||
Verifying plant reliability includes - ✔✔Frequency response sweeping, which is adjusting
|| || || || || || || || || || ||
RF amplifier circuits to amplify all frequencies in the bandpass spectrum as equally as
|| || || || || || || || || || || || || ||
possible

system components and 3 meters from the ground.
|| || || || || || ||
Many cable companies require which type of leaks to be fixed? - ✔✔All types of leaks must

|| || || || || || || || || || || || || || ||
probable cause of the leakage. || || || ||
Which of the following FCC required information must a cable system keep on file for two
|| || || || || || || || || || || || || || || ||
years? - ✔✔Annual CLI calculations, regular (quarterly) monitoring programs, and a list of
|| || || || || || || || || || || || ||
all channels used in the aeronautical bands.
|| || || || || ||
If your leakage detector indicates there is a leak and displays a reading of 14 microvolts per
|| || || || || || || || || || || || || || || || ||
meter (uV/m) when you are 80 feet from a possible leak source, what is the approximate
|| || || || || || || || || || || || || || || ||
calculated level of the leak from 10 feet? - ✔✔112 uV/m. || || || || || || || || || ||
If a large signal leak is found in the aerial plant, what is a good first step in locating the
