NCTI Field Tech 2 to 3 Questions and Correct Answers 2024

What is one reason why broadband cable operators install fiber optic cables in stages instead of changing the infrastructure all at once - Correct Answer Changing the infrastructure all at once would cause too many service disruptions What is the difference between FTTN and FTTC - Correct 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) - Correct 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 - Correct Answer Distributed Star Which element of a PON(Passive Optical Network) uses a Bragg grating filter - Correct Answer OLT(Optical Line Terminal) Which element of a PON(Passive Optical Network) uses Patch Panels - Correct 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) - Correct 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 - Correct 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 - Correct Answer Fiber-optic cable with pre-connectorized ends
