Conventional Questions and answers
(100% well Illustrated)
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

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
(20) / (-4) + (-2) x (-10) - (-2) x (7) = - Answer 29
3 6/9 + 6 1/3 + 9 5/9 = - Answer 19 5/9
