NCTI MT1 to MT2 Questions and Correct Answers 2024

According to SCTE- and NCTA- recommended trunk system map symbols, fiber-optic cable is represented by - Correct Answer Double arrows within a small circle on a solid line. The forward path signal in a traditional tree-and-branch architecture - Correct Answer originates at the headend and is transmitted downstream through coaxial trunk cable and trunk amplifier. In a HFC network, - Correct Answer Processing equipment in the headend converts the forward RF signal to a light signal. During aerial plant construction, - Correct Answer The strand is tensioned so its sag profile matches that of the overhead utility power lines. With underground plant construction, - Correct Answer The fiber-optic and coaxial cables are often places underground with other utility lines to jointly share construction costs. Standby power supplies - Correct Answer continue providing an output voltage even during a utility power outage by using a back up power source. Centralized power configurations - Correct Answer provide the advantage of increased reliability through sharing of expensive backup generators and sophisticated monitoring equipment among different power realms. When transmitting broadband signals - Correct Answer 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 - Correct Answer Have attenuator pads, equalizers, and duplex filters that control and route the RF signals. Verifying plant reliability includes - Correct Answer Frequency response sweeping, which is adjusting RF amplifier circuits to amplify all frequencies in the bandpass spectrum as equally as possible
