Progression: Field Tech II - IIIConventional Exam/190 Questions &
Answers
What is one reason why broadband cable operators install fiber-optic cable in
stages instead of changing the infrastructure all at once? - -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? - -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)? - -
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? - -Distributed
star.
-Which element of a passive optical network (PON) uses a Bragg grating
filter? - -Optical line terminal (OLT).
-Which element of a passive optical network (PON) uses patch panels? - -
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)? - -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? - -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? - -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? - -Before
stripping the plastic coating from the fiber.
,-Which of the following are statements of true axioms? - -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 = ? - -E/R
-The square of 7 = - -49
-The square root of 81 = - -9
-0.00004 = ______ x 10 to the power of ______. - -4, -5
-(75 x 10 to the power of 3) + (25 x 10 to the power of 4) = - -32.5 x 10 to
the power of 4
-10 to the power of -3 has a metric prefix of ______. - -Milli
-(480 x 10 to the power of -5) divided by (60 x 10 to the power of -3) = - -8
x 10 to the power of -2
-(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = - -180 x 10 to
the power of -6
-(75 × 103) + (25 × 104) = - -(*Wrong) 100 × 10^3
-(-25) + (42) + (-62) + (20) = - --25
-(17) x (-19) = - --323
-(-17) - (-34) = - -17
--49/-7 = - -7
-(20) / (-4) + (-2) x (-10) - (-2) x (7) = - -29
-3 6/9 + 6 1/3 + 9 5/9 = - -19 5/9
-4/7 x 9 4/11 = - -5 27/77
-7 3/8 divided by 7 1/4 = - -1 1/58
-8.13 X 0.123 = - -0.99999
-0.5349 divided by 0.1420 = - -3.7669014
