Progression: Field Tech II - III Conventional Questions And 100%Correct Answers Graded A+ Updated 2024. What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - 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? - 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 network (PON)? - Optical splitters. Which type of star topology used in a passive optical network (PON) places the PON splitters into fiber access terminal (FAT) located deep in the network and closer to the customer premises than the centralized split? - Distributed star. Which element of a passive optical network (PON) uses a Bragg grating filter? - Optical line terminal (OLT). Which element of a passive optical network (PON) uses patch panels? - Optical distribution network (ODN). What is it about radio frequency over glass (RFoG) that made broadband cable operators envision using it to make a seamless transition from the legacy hybrid fiber/coax (HFC) architecture over to a gigabit-capable passive optical network (GPON) or Ethernet passive optical network (EPON)? - RFoG can operate in parallel with GPON or EPON, which eliminates the need for any downtime during the transition. How are optical splitters used in the forward path? - In the forward path, optical splitters are used as passive branching devices that divide an optical signal across multiple output fibers. Progression: Field Tech II - III Conventional Questions and Answers Already Graded A+ Which of the following describes a fiber pigtail? - Fiber-optic cable with pre-connectorized ends. Heat shrink tubing is installed over the fusion-splice to strengthen and protect it. When should the heat shrink be installed on the fiber? - Before stripping the plastic coating from the fiber. Which of the following are statements of true axioms? - When A = C and B = C, then A = B because both are equal to C, which supports the axiom: Quantities equal to the same quantity are equal to each other. Simplify and solve the equation: If E = IR then I = ? - E/R The square of 7 = - 49 The square root of 81 = - 9 0.00004 = ______ x 10 to the power of ______. - 4, -5 (75 x 10 to the power of 3) + (25 x 10 to the power of 4) = - 32.5 x 10 to the power of 4.
