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 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
(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
