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


The square root of 81 = - 🧠 ANSWER ✔✔9


0.00004 = ______ x 10 to the power of ______. - 🧠 ANSWER ✔✔4, -5

✔✔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) = - 🧠 ANSWER ✔✔17


-49/-7 = - 🧠 ANSWER ✔✔7


(20) / (-4) + (-2) x (-10) - (-2) x (7) = - 🧠 ANSWER ✔✔29


3 6/9 + 6 1/3 + 9 5/9 = - 🧠 ANSWER ✔✔19 5/9


4/7 x 9 4/11 = - 🧠 ANSWER ✔✔5 27/77
