What is one reason why 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.
What is the difference between the fiber-to-the-node (FTTN) and
fiber-to-the-curb (FTTC) topologies? -- correct 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)? -- correct 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? -- correct answer --Distributed star.
,Which element of a passive optical network (PON) uses a Bragg
grating filter? -- correct answer --Optical line terminal (OLT).
Which element of a passive optical network (PON) uses patch panels?
-- correct 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)? -- correct 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? -- correct 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? -- correct 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? -
- correct answer --Before stripping the plastic coating from the fiber.
,Which of the following are statements of true axioms? -- correct
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 = ? -- correct answer -
-E/R

(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = -- correct
answer --32.5 x 10 to the power of 4
10 to the power of -3 has a metric prefix of ______. -- correct answer --
Milli
(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) =
-- correct answer --8 x 10 to the power of -2
(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = -- correct
answer --180 x 10 to the power of -6
(75 × 103) + (25 × 104) = -- correct answer --(*Wrong) 100 × 10^3
(-25) + (42) + (-62) + (20) = -- correct answer ---25

(-17) - (-34) = -- correct answer --17
-49/-7 = -- correct answer --7
(20) / (-4) + (-2) x (-10) - (-2) x (7) = -- correct answer --29
3 6/9 + 6 1/3 + 9 5/9 = -- correct answer --19 5/9
4/7 x 9 4/11 = -- correct answer --5 27/77
7 3/8 divided by 7 1/4 = -- correct answer --1 1/58
8.13 X 0.123 = -- correct answer --0.99999
0.5349 divided by 0.1420 = -- correct answer --3.7669014
Which of the following is a method for controlling expectations? --
correct answer --Identify the source of emotional overload.
Which of the following best describes stereotyped thinking? -- correct
answer --Presuming that all members of a group have certain
characteristics.
The attribute of being "active" as a critical thinker means -- correct
answer --You observe and take notes relevant to the issue.
What kind of reasoning is described as applying a general statement
