NCTI Field Tech 2 to 3 Questions and Answers Graded A What is one reason why broadband cable operators install fiber optic cables 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 FTTN and FTTC ✔✔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) ✔✔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 ✔✔Distributed Star Which element of a PON(Passive Optical Network) uses a Bragg grating filter ✔✔OLT(Optical Line Terminal) Which element of a PON(Passive Optical Network) uses Patch Panels ✔✔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) ✔✔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 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.
