190 Questions with Correct Answers 100% Verified What is one reason why broadband cable operators install fiber-optic cable 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 the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies? - Correct Answer 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)? - Correct Answer 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? - Correct Answer Distributed star.Which element of a passive optical network (PON) uses a Bragg grating filter? - Correct Answer Optical line terminal (OLT).Which element of a passive optical network (PON) uses patch panels? - Correct Answer 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)? - 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. 1 / 3
Which of the following describes a fiber pigtail? - Correct 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? - Correct Answer Before stripping the plastic coating from the fiber.Which of the following are statements of true axioms? - Correct Answer 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.
