Terms in this set (190)  What is one reason why broadband cable operators install fiberoptic 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 the difference between the fiber-to-thenode (FTTN) and fiber-tothe-curb (FTTC) topologies? An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises.

What topology is used in passive optical network (PON) architectures? - ANSWER Passive optical network (PON) architectures use fiber-to-the-premises (FTTP) topologies to make point-to-multipoint (P2MP) connections between the broadband cable headend and the customer premises. What are the three categories of fiber-optic cable in a PON? - ANSWER The fiber-optic cable in a PON is placed in one of three categories, trunk, branch, and drop, to identify the cable's location in the network

What is unique about WDM - PON ? - ANSWER WDM-PON deployed in a greenfield system allows each subscriber to get their own designated wavelength. What is the main benefit of deploying WDM technology? - ANSWER It will increase the capacity of the existing fiber networks tenfold without adding any more fiber. How are optical splitters used in the forward path? - ANSWER As passive branching devices that divide an optical signal across multiple output

How are optical splitters used in the forward path? - ANSWER As passive branching devices that divide an optical signal across multiple output

The open system interconnection reference model (OSI/R<) Network layer serves which primary function? - ANSWER It uses layer 3 addresses to create multiple routed networks The address 68.56.189.17 belongs to which internet protocol IP class? - ANSWER Class A What happens to a datagram sent by a higher level protocol to a 127.x.y.z address? - ANSWER The datagram loops back inside the host and never leaves the network interface card (NIC)

The Open Systems Interconnection reference model (OSI/RM) Network Layer serves which primary purpose? - ANSWER It uses Layer 3 addresses to create multiple routed networks. The address 68.56.189.17 belongs to which Internet protocol (IP) class? - ANSWER Class A. What happens to a datagram sent by a higher level protocol to a 127.x.y.z address? - ANSWER The datagram loops back inside the host and never leaves the network interface card (NIC).
