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.
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.
Which of these components is used in a passive optical network (PON)? -
✔✔-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? - ✔✔-Distributed star.
Which element of a passive optical network (PON) uses a Bragg grating filter? -
✔✔-Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels? -
✔✔-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)? - ✔✔-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? - ✔✔-In the forward path,
optical splitters are used as passive br
