FIELD TECH II III CONVENTIONAL
COMPREHENSIVE EXAM STUDY GUIDE
WITH COMPLETE SOLUTIONS
●● 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 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 these components is used in a passive optical network
(PON)?
Answer: Optical splitters
, ●● 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
