And Answers |Latest 2025 | Guaranteed Pass
What uses the 2.4-GHz band and runs at 54 Mbps? - Answer✔802.11g
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
