NCTI Field Tech 2 to 3 (NCTI Course 1 Material) with Complete Solutions

What is one reason why broadband cable operators install fiber optic cables 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 FTTN and FTTC - ANSWER-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 PON(Passive Optical Network) - ANSWER-Optical Splitters Which type of Star topology used in a PON(Passive Optical Network) places the PON splitters into FATS(Fiber Access Terminals) located deep in the network and closer to the customer premises than the centralized split - ANSWER-Distributed Star Which element of a PON(Passive Optical Network) uses a Bragg grating filter - ANSWER-OLT(Optical Line Terminal) Which element of a PON(Passive Optical Network) uses Patch Panels - ANSWER-ODN(Optical Distribution Network) 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) - ANSWER-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 - ANSWER-In the forward path, optical splitters are used as passive branching devices that divide an optical signal across multiple output fibers Which of the following describes a fiber pigtail - ANSWER-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 - ANSWER-Before stripping the plastic coating from the fiber Which of the following is a method for controlling expectations - ANSWER-focus on the bigger picture rather than smaller tasks Which of the following best describes stereotyped thinking - ANSWER-Presuming that all members of a group have certain characteristics The attribute of being "active" as a critical thinker means - ANSWER-You observe and take notes relevant to the issue What kind of reasoning is described as applying a general statement that you know to be true to a new situation - ANSWER-Deductive
