correctly answered graded A+ 2023 passed
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 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 these components is used in a passive optical network (PON)? - correct answer Optical splitters
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
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) = - 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
(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.
