NCTI Charter Communications Fiber - Lesson 1 Questions and Answers 2023 What does the hybrid fiber/coax (HFC) network architecture offer broadband cable operators? HFC network architectures have been developed to enable broadband cable operators to make a gradual, or staged, transition to an all fiber-optic cable infrastructure. Which fiber-to-the-x topology has amplifiers in the coaxial cable portion of the network? Additional RF amplifiers may be in the coaxial cable portion of the f...

Which of the following devices were used to capture TV signals in the early days of television? A) Microwave Antenna. B) Antenna placed on the roof. C) Satellite Dish. D) Dowser Rod. B) Antenna placed on the roof. Why did cable companies implement microwave technology? A) Because the equipment was inexpensive. B) Largely because the microwave signal was not amplified to reach the cable system. C) To obtain a better signal quality than antenna-delivered signal could offer. D) To f...

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 s...
