AND CORRECT DETAILED ANSWERS
What uses the 2.4-GHz band and runs at 54 Mbps? - (answer) 802.11g
What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing
the infrastructure all at once? - (answer) Changing 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? -
(answer) An 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)? - (answer) Optical 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? - (answer) Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? - (answer) Optical line
terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? - (answer) Optical 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)? - (answer) RFoG
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? - (answer) In the forward path, optical splitters are
used as passive branching devices that divide an optical signal across multiple output fibers.
