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
, 2
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.
Which of the following describes a fiber pigtail? - (answer)Fiber-optic cable
with pre-connectorized ends.
Heat shrink tubing is installed over the fusion-splice to strengthen and protect
it. When should the heat shrink be installed on the fiber? - (answer)Before
stripping the plastic coating from the fiber.
Which of the following are statements of true axioms? - (answer)When A = C
and B = C, then A = B because both are equal to C, which supports the axiom:
Quantities equal to the same quantity are equal to each other.
Simplify and solve the equation: If E = IR then I = ? - (answer)E/R

(-25) + (42) + (-62) + (20) = - (answer)-25
(17) x (-19) = - (answer)-323
(-17) - (-34) = - (answer)17
-49/-7 = - (answer)7
(20) / (-4) + (-2) x (-10) - (-2) x (7) = - (answer)29
3 6/9 + 6 1/3 + 9 5/9 = - (answer)19 5/9
4/7 x 9 4/11 = - (answer)5 27/77
7 3/8 divided by 7 1/4 = - (answer)1 1/58
