FTTX Basics Exam: Guaranteed Pass, Exams of Nursing

A comprehensive overview of the key concepts and technical details related to fttx (fiber-to-the-x) network topologies and technologies. It covers the differences between fttn (fiber-to-the-node) and fttc (fiber-to-the-curb) topologies, the three categories of fiber-optic cables used in fttx networks, the various pon (passive optical network) elements and their functions, the benefits of wdm (wavelength division multiplexing) technology, the best practices for repairing aerial fiber-optic drop cables, and the characteristics of itu-t g.657 bend-insensitive fiber. The document also addresses the importance of proper fiber handling, the purpose of ground blocks, and the critical parameters for otdr (optical time-domain reflectometer) testing in pon networks. This comprehensive guide is designed to help network professionals and students gain a deep understanding of fttx technology and prepare for the fttx basics exam.

FTTX BASICS EXAM |GUARANTEED PASS What is the difference between the FTTN and FTTC topologies? - ACCURATE ANSWERS✔✔ An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. What are the three categories of fiber-optic cable used to identify the location of the fiber in the network? - ACCURATE ANSWERS✔✔ Trunk, branch, and drop Which type of fiber topology used in a PON places the PON splitters at the headend while providing one designated fiber for every customer premise? - ACCURATE ANSWERS✔✔ Home-run Which PON element uses patch panels ? - ACCURATE ANSWERS✔✔ ODN What is one of the main functions of the FDH? - ACCURATE ANSWERS✔✔ The FDH provides effective fiber management by grouping splitters into local serving areas. What is the purpose of the MST? - ACCURATE ANSWERS✔✔ It provides access to connect fiber-optic cable drops from the customer premises to the network. What is the purpose of a fiber demarcation box? - ACCURATE ANSWERS✔✔ It provides a safe place to splice, split, distribute, store, and cross-connect fiber optics. How are optical splitters used in the forward path? - ACCURATE ANSWERS✔✔ As passive branching devices that divide an optical signal across multiple output fibers. What is the main benefit of deploying WDM technology? - ACCURATE ANSWERS✔✔ It will increase the capacity of the existing fiber networks tenfold without adding any more fiber What is unique about WDM-PON? - ACCURATE ANSWERS✔✔ WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. What is the best approach to repairing an aerial fiber-optic drop cable for FTTx applications? - ACCURATE ANSWERS✔✔ Replace the entire section of fiber drop cable. What is the purpose of the SDU? - ACCURATE ANSWERS✔✔ It provides surge protection, a test jack, circuit protection, wiring management, and fiber termination. What are some of the advantages of loose buffer tube fiber? - ACCURATE ANSWERS✔✔ It offers the best protection for the fibers under high pulling tension and moisture with its fiber-coated gel.
