Path to Field Tech I and II (To Advance to FT III) Questions & Answers 100% Correct

Path to Field Tech I and II (To Advance to FT III) Questions & Answers 100% Correct What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? - ANSWER-HFC network architectures have been developed to enable broadband cable operators to make a gradual, or staged, transition to an all fiber-optic cable infrastructure. Which fiber-to-the-x topology has amplifiers in the coaxial cable portion of the network? - ANSWER-Additional RF amplifiers may be in the coaxial cable portion of the fiber-to-the-node (FTTN) topology to maintain proper amplitude levels of the RF signal throughout the serving area. What topology is used in passive optical network (PON) architectures? - ANSWER-Passive optical network (PON) architectures use fiber-to-the-premises (FTTP) topologies to make point-to-multipoint (P2MP) connections between the broadband cable headend and the customer premises. What are the three categories of fiber-optic cable in a PON? - ANSWER-The fiber-optic cable in a PON is placed in one of three categories, trunk, branch, and drop, to identify the cable's location in the network What variations of the star topology are used in PONs? - ANSWER-Centralized split, distributed star, and home-run are variations of the star topology used in PONs. What does the radio frequency over glass (RFoG) architecture provide as envisioned by broadband cable operators? - ANSWER-RFoG was envisioned to provide operators with the time to make a seamless transition from the legacy hybrid fiber/coax (HFC) architecture over to gigabit PON (GPON) or Ethernet PON (EPON).
