FIELD TECH 2 SCTE UPDATED EXAM SCRIPT
WITH COMPLETE ANSWERS
◉ What is one reason why broadband cable operators install fiber-
optic cable in stages instead of changing the infrastructure all at
once?
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?
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)?
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?
Answer: Distributed star.
,◉ Which element of a passive optical network (PON) uses a Bragg
grating filter?
Answer: Optical line terminal (OLT).
◉ Which element of a passive optical network (PON) uses patch
panels?
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)?
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?
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?
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?
Answer: Before stripping the plastic coating from the fiber.
◉ Which of the following are statements of true axioms?
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 = ?
Answer: E/R
◉ The square of 7 =
Answer: 49
◉ The square root of 81 =
Answer: 9
◉ 0.00004 = ______ x 10 to the power of ______.
Answer: 4, -5
◉ (75 x 10 to the power of 3) + (25 x 10 to the power of 4) =
, Answer: 32.5 x 10 to the power of 4
◉ 10 to the power of -3 has a metric prefix of ______.
Answer: Milli
◉ (480 x 10 to the power of -5) divided by (60 x 10 to the power of -
3) =
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) =
Answer: 180 x 10 to the power of -6
◉ (75 × 103) + (25 × 104) =
Answer: (*Wrong) 100 × 10^3
◉ (-25) + (42) + (-62) + (20) =
Answer: -25
◉ (17) x (-19) =
Answer: -323
◉ (-17) - (-34) =
