QUESTIONS WITH COMPLETE SOLUTIONS
◉ What type of fiber-to-the-x (FTTx) topology does a passive optical
network (PON) use to make a point-to-multipoint (P2MP) fiber-
optic cable connection between the broadband cable headend and
the customer premises? Answer: FTTH
◉ In a PONPassive optical network, which category of fiber-optic
cable is routed from the headend into the ODNOptical distribution
network? Answer: Trunk
◉ Which type of PONPassive optical network topology places the
optical splitters at the headend and then routes them to each
customer premises? Answer: Home-run
◉ Which PON access architecture type replaced the APON? Answer:
BPON
◉ Which type of PON architecture was formed to develop a cost-
effective, high-bandwidth, easy-to-provision solution for connecting
businesses, schools, libraries, and customer local area networks to
the public Internet? Answer: EPON
, ◉ What about RFoG made broadband cable operators envision using
it to make a seamless transition from the legacy HFC architecture
over to a GPON or EPON? Answer: RFoG can operate in parallel with
GPON and EPON, independent of the PON communications protocols
and data rates.
◉ What is the core objective of the DOCSIS provisioning of EPON, or
DPoE, access architecture? Answer: To make the EPON elements
appear and operate as DOCSIS elements to the existing DOCSIS-
based back office provisioning operations.
◉ What is one of the requirements that have been identified for NGA
network architectures? Answer: Smaller split ratios.
Increased power consumption.
***Expanded troubleshooting capability.***
Shorter distances for transporting light waves.
◉ What is the maximum data rate the XG-PON (10 Gigabit
Asymmetric Passive Optical Network) access architecture supports
in the upstream? Answer: 2.5 Gbps
◉ For a 1-G-EPON NGA architecture with a downstream speed of
10Gbps, what are the two upstream data rates that are supported)?
Answer: 1 Gbps and 10 Gbps.
