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 causetoo 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 fiberand 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 deepin 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 overto a gigabit-capable passive optical network (GPON) or Ethernet passive optical
network (EPON)? -- correct answer --RFoG can operatein 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 toC, 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
The square of 7 = -- correct answer --49
, The square root of 81 = -- correct answer --9
0.00004 = x 10 to the power of . -- correct answer --4, -5
(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = -- correctanswer --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
(20) / (-4) + (-2) x (-10) - (-2) x (7) = -- correct answer --29
