Progression: Maintenance Tech I - II
Conventional NCTI 2020
According to SCTE- and NCTA-recommended trunk system map symbols, fiber-optic
cable is represented by - ✔ Double arrows within a small circle on a solid line.
The forward path signal in a traditional tree-and-branch architecture - ✔ Originates at
the headend and is transmitted downstream through coaxial trunk cable and trunk
amplifiers.
In an HFC network, - ✔ Processing equipment in the headend converts the forward RF
signal to a light signal.
During aerial plant construction, - ✔ The strand is tensioned so its sag profile matches
that of the overhead utility power lines.
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
power outage by using a backup power source.
Centralized power configurations - ✔ Provide the advantage of increased reliability
through sharing of expensive backup generators and sophisticated monitoring
equipment among different power realms.
When transmitting broadband signals - ✔ 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 - ✔ 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
Which of the following is a requirement in the process for measuring leakage using a
dipole antenna, as required by the FCC? - ✔ 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? - ✔ All types of leaks
must be fixed.
