Distribution amplifiers - Study guides, Class notes & Summaries

Customer premises - Connected to the network through distribution taps spliced into the coaxial cable. Branches in the architecture - The downstream signal is distributed within nearby neighborhoods using 0.412-inch to 0.625-inch diameter coaxial cable, splitters, and directional couplers. Bridger amplifier - A portion of the downstream signal is boosted before being split and routed to as many as four separate coaxial cables—the branches in the architecture. Trunk amplifiers - Seve...

NCTI - Installer Book 2023/2024 EXAM. Which of the following will strengthen signals as they move farther away from the headend through the trunk express system? B) Distribution amplifiers. Which of the following describes a carrier wave? B) A wave with a much higher frequency than the input signal. Which of the following describes modulation?

What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? Answer Changing the infrastructure all at once would cause too many service disruptions. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies? Answer An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. Which of these components is used in a passive optical...
