What uses the 2.4-GHz band and runs at 54 Mbps? - ANSWER802.11g
What is one reason why broadband cable operators install fiber-optic cable in stages
instead of changing the infrastructure all at once? - ANSWERChanging the
infrastructure all at once would cause too many service disruptions.
What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb
(FTTC) topologies? - ANSWERAn FTTC is allowed a smaller number of RF amplifiers
between the optical fiber and the customer premises.
Which of these components is used in a passive optical network (PON)? -
ANSWEROptical splitters.
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? - ANSWERDistributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
ANSWEROptical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? -
ANSWEROptical distribution network (ODN).
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)? - ANSWERRFoG can operate in parallel
with GPON or EPON, which eliminates the need for any downtime during the transition.
How are optical splitters used in the forward path? - ANSWERIn the forward path,
optical splitters are used as passive branching devices that divide an optical signal
across multiple output fibers.
Which of the following describes a fiber pigtail? - ANSWERFiber-optic cable with pre-
connectorized ends.

should the heat shrink be installed on the fiber? - ANSWERBefore stripping the plastic
coating from the fiber.

intermittent or constant. Which step are you using from the six-step troubleshooting
process? - ANSWERIdentifying the problem.
Why should you take the time to take notes and accurately record data at each job
location? - ANSWERNotes and recorded data are tools that can help you accurately
remember events at a site that can help you determine a plan of action or evaluate the
decisions you made.
You are at a customer's home and you believe you have solved the problem. When you
check to be sure the resolution did not introduce any new problems, which step are you
using from the six-step troubleshooting process? - ANSWERVerifying the solution.
