ROC II, Course II, Lesson 22

What does a point-to-multipoint (P2MP) topology consist of?

a P2MP topology consists of a host element connected through a splitter or optical coupler to two or more receiving elements

What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies?

an FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises

What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once?

changing the infrastructure all at once would cause too many service disruptions

What is an example of transport media in a telecommunications network?

coaxial cable

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?

distributed star

What type of fiber-to-the-x (FTTx) topology does a passive optical network (PON) use to make a point-to-multipoint (P2MP) fiber-optic cable connection between the broadband cable headend and the customer premises?

fiber-to-the-home (FTTH)

Which answer best describes network topology?

it's a sub-layer of network architecture that describes the physical and logical configuration of connected elements between the signal source and the network termination elements

Which type of network topology has been focused primarily on alternative routing around cities and industrial areas?

ring

Which type of network topology allows troubleshooting a problem or switching around the problem to be accomplished easily from the central hub?

star

In a passive optical network (PON), which category of fiber-optic cable is routed from the headend into the optical distribution network (ODN)?

trunk
