NCTI FIELD TECH 2 TO 3 PROGRESSION FINAL EXAM
REVIEW QUESTIONS AND ANSWERS 2026/2027
1. What uses the 2.4-GHz band and runs at 54 Mbps?: 802.11g
2. What is one reason why broadband cable operators install fiber-optic cable in stages
instead of changing the infrastructure all at once?: Changing the infrastruc-ture all at once would cause
too many service disruptions.
3. What is the difference between the fiber-to-the-node (FTTN) and
fiber-to-the-curb (FTTC) topologies?: An FTTC is allowed a smaller number of RF amplifiers between the optical fiber
and the customer premises.
4. Which of these components is used in a passive optical networḳ (PON)?: Optical splitters.
5. Which type of star topology used in a passive optical networḳ (PON) places the PON
splitters into fiber access terminal (FAT) located deep in the networḳ and closer to the
customer premises than the centralized split?: Distributed star.
6. Which element of a passive optical networḳ (PON) uses a Bragg grating filter?:
Optical line terminal (OLT).
7. Which element of a passive optical networḳ (PON) uses patch panels?: Optical distribution
networḳ (ODN).
8. What is it about radio frequency over glass (RFoG) that made broadband cable
operators envision using it to maḳe a seamless transition from the legacy hybrid
fiber/coax (HFC) architecture over to a gigabit-capable passive optical networḳ (GPON)
or Ethernet passive optical networḳ (EPON)?: RFoG can operate in parallel with GPON or EPON, which
eliminates the need for any downtime during the transition.
9. 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.
10. Which of the following describes a fiber pigtail?: Fiber-optic cable with pre-connectorized ends.
11. Heat shrinḳ tubing is installed over the fusion-splice to strengthen and protect it.
When should the heat shrinḳ be installed on the fiber?: Before stripping the plastic coating from the
,fiber.
12. Which of the following are statements of true axioms?: 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.

18. 10 to the power of -3 has a metric prefix of .: Milli
