Answers With Rationales A Grade
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
infrastructure 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 network (PON)?: Optical
splitters.
5. 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?: Distributed star.
6. Which element of a passive optical network (PON) uses a Bragg grating filter?:
Optical line terminal (OLT).
7. Which element of a passive optical network (PON) uses patch panels?: Optical
distribution network (ODN).
8. 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)?: 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 shrink tubing is installed over the fusion-splice to strengthen and protect
it. When should the heat shrink 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.
