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 traditi... onal tree-and-branch architecture originates at the headend and is transmitted downstream through coaxial trunk cable and trunk amplifier. In a 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 places 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 back up 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 duplex 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. According to the FCC, the leakage log should contain which of the following? The 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 leak? Drive around until an absolute peak is found. Which of the following best describes demand maintenance procedures with regard to signal leakage? 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? 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. [Show More]
