Which of the following echelon amplifiers represents a team or crew? - ANSWER : Hollow Circle with one diagonal line. Which of the fo...

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...

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? B) The reshaping of a carrier wave to include information contained by an input signal. Which of the following is the symbol for power? W = watt...

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 type of star topology used in a passive optical ...

Chapters 19, 20,21, 23, 24 Ch 19 Thorax and Lungs – Pages 405- 450 Lobes of the lungs • The right lung is shorter than the left lung and has three lobes, whereas the left lung has two. • Separated by fissures - double folds of pleura that divide the lung into lobes o Liver underneath Right lung o Heart bulges to the left- making Left lung narrower Symmetric expansion (Palpate) Technique: place both hands/thumbs pointing together at the level of T9 or T10- medially pinch a small f...

NCTI Final Exam Maintance Tech 2-3 Conventional| New Update 2023/ 2024| Verified Questions and ANSWERs In a hybrid fiber/coax HFC fiber optic node, what are common voltages produced by DC power supplies? - ANSWER Common Voltage includes +5, +12 and +24 VDC Why do many optical nodes accept two independent power supplies? - ANSWER For redundant Powering of the node. What is an o...

What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - ANSWER-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? - ANSWER-Additional RF amplifiers may be in the coaxial cable portion of the fiber-to-the-node...

What is the difference between the FTTN and FTTC topologies? Answer An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What are the three categories of the fiber-optic cable used to identify the location of the fiber in the network? Answer Truck, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise? Answer Home-run Which PO...
