Field Tech II - III Conventional Exam
Questions And Answers 2026
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 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-32.5 × 104
(-25) + (42) + (-62) + (20) = - Correct Answer--25
(17) x (-19) = - Correct Answer--323
(-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
