Which fiber-optic cable design category typically uses some star topology variation? - correct answer
⦁ Signal distribution.
What is the ideal way for a broadband cable network designer to plan the replacement of coaxial cable
with fiber-optic cable to shorten amplifier cascades? - correct answer ⦁ Use the
existing coaxial network infrastructure.
What is an option for a broadband cable network to maximize the use of its optical fiber resources? -
correct answer ⦁ Leasing spare fibers.
Which of these items should be identified on a route map so that the design can provide (or not provide)
special network access? - correct answer ⦁ Parks
Which type of map contains node information? - correct answer ⦁ Design map.
How many meters of slack cable is typically used in an aerial installation? - correct answer
⦁ 15-25 meters.
What is one example of a stipulation in a franchise agreement that would affect network design? -
correct answer ⦁ A 100% fiber-optic network.
When activating a fiber-optic network, which acceptance-testing stage includes adjusting attenuation
levels for the first time? - correct answer ⦁ During equipment activation.
What information should always be included in fiber-optic network documentation? - correct answer
⦁ Fiber assignments.
, When troubleshooting an outage in an optical network, why would a technician want to refer to the
network's as-built documentation? - correct answer ⦁ To help determine specific
cable lengths.
What is an example of transport media in a telecommunications network? - correct answer
⦁ Coaxial cable.
Which of the following describes how the signal is transported through the network without following
the physical path requirements of the peripherals? - correct answer ⦁ Logical
topology.
Which topology consists of a host element connected to two or more receiving elements through a
splitter or optical coupler? - correct answer ⦁ P2MP (Point-to-multipoint) topology. *
Which type of network topology allows troubleshooting a problem or switching around the problem to
be accomplished easily from the central hub? - correct answer ⦁ Star.
Which type of network topology has been focused primarily on alternative routing around cities and
industrial areas? - correct answer ⦁ Ring
What is one reason broadband cable operators install fiber-optic cable in stages instead of changing the
infrastructure all at once? - correct answer ⦁ Changing the infrastructure all at once
would cause too many service disruptions.
Which topology allows a smaller number of radio frequency (RF) amplifiers between the optical fiber
and the customer premises? - correct answer ⦁ FTTC (Fiber-to-the-curb)
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? - correct answer ⦁ FTTH (Fiber-to-the-home)
