According to SCTE- and NCTA- recommended trunk system map symbols, fiber-optic cable is
represented by - ANS Double arrows within a small circle on a solid line.
The forward path signal in a traditional tree-and-branch architecture - ANS originates at the
headend and is transmitted downstream through coaxial trunk cable and trunk amplifier.
In a HFC network, - ANS Processing equipment in the headend converts the forward RF signal
to a light signal.
During aerial plant construction, - ANS The strand is tensioned so its sag profile matches that
of the overhead utility power lines.
With underground plant construction, - ANS The fiber-optic and coaxial cables are often
places underground with other utility lines to jointly share construction costs.
Standby power supplies - ANS continue providing an output voltage even during a utility
power outage by using a back up power source.

,Centralized power configurations - ANS provide the advantage of increased reliability
through sharing of expensive backup generators and sophisticated monitoring equipment
among different power realms.
When transmitting broadband signals - ANS In a two way hybrid fiber/coax (HFC) network,
two or more individual optical fibers are required for each optical node location.
RF trunk amplifiers - ANS Have attenuator pads, equalizers, and duplex filters that control
and route the RF signals.
Verifying plant reliability includes - ANS Frequency response sweeping, which is adjusting RF
amplifier circuits to amplify all frequencies in the bandpass spectrum as equally as possible
Which of the following is a requirement in the process for measuring leakage using a dipole
antenna, as required by the FCC? - ANS The antenna must be placed 3 meters from the
system components and 3 meters from the ground.
Many cable companies require which type of leaks to be fixed? - ANS All types of leaks must
be fixed.
According to the FCC, the leakage log should contain which of the following? - ANS The
probable cause of the leakage.
Which of the following FCC required information must a cable system keep on file for two
years? - ANS 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? - ANS 112 uV/m.

, If a large signal leak is found in the aerial plant, what is a good first step in locating the leak? -
ANS Drive around until an absolute peak is found.
Which of the following best describes demand maintenance procedures with regard to signal
leakage? - ANS The demand maintenance procedures can improve the CLI measurement
results by identifying and correcting the largest leaks first.
When troubleshooting signal leakage in the drop system, what is indicated if all signs of signal
leakage disappear when the ground block is disconnected and terminated on the side
connected to the customer premises? - ANS The backward route from the ground block to
the tap can be eliminated as a source of The backward route from the ground block to the tap
can be eliminated as source of leakage.
Which typical over-the-air signal sources can cause a false alarm with a signal leakage detector?
- ANS Typical sources include aircraft communication signals and ham, mobile, and
government radio broadcasts.
When adjusting or selecting the elements of a dipole antenna for measuring signal leakage,
what is the approximate length of each element relative to the wavelength of the signal being
measured? - ANS One-quarter wavelength.
Which of the following problem(s) are caused by egress? - ANS Interference with
aeronautieal navigation
and communication, amateur radio public service, and cellular communications.
What cumulative leakage index (CLI) meets Federal Communications Commission (FCC)
requirements? - ANS 64 or less
What is the maximum allowable signal detectable in the airspace during a flyover? - ANS 10
uv/m.
