Path To Field Tech I And II (To Advance To FT III) Questions And Answers 2025/2026

Path To Field Tech I And II (To Advance To FT III) Questions And Answers 2025/2026 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? - answerAdditional 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). What are the three primary elements of a PON? - answer-Using terminology from the telephone industry, the main elements of a PON are the optical line terminal (OLT), the optical distribution network (ODN), and the optical network unit (ONU).In FTTx networks, what is required to power ONTs at the customer premises? - answer-AC power must be provided at the customer premises in the case of RFoG installations to power the ONT. What are optical splitters? - answer-Optical splitters are passive branching devices that divide an optical signal across a number of output ports in the forward direction, and combine multiple signals onto a common optical fiber in the return direction. Why can FTTx applications be more susceptible to the adverse effects of macro- and microbends bends than typical transmission applications? - answer-FTTx standards use some wavelengths that are longer than typical transmission wavelengths, and are therefore more susceptible to the adverse effects of macro- and microbends. What is the smallest allowable bend radius for G.652 standard single-mode fiber? - answer-The smallest allowable bend radius for G.652 standard single-mode fiber is 30 mm.
