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)? -- correct 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

passive optical network (EPON)? -- correct 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? -- correct 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? -- correct answer --

(250 x 10 to the power of -6) - (7 x 10 to the power of -5) = -- correct

answer --180 x 10 to the power of -6

(75 × 103) + (25 × 104) = -- correct answer --(*Wrong) 100 × 10^3
