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? - ---

and B = C, then A = B because both are equal to C, which supports the axiom:

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
