Optical fiber is used by telecommunications companies to transmit telephone signals, Internet communication and cable television signals. In 1880, and his assistant created a very early precursor to fiber-optic communications, the, at Bell's newly established in.

Fiber to the x (FTTX; also spelled "fibre") or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone networks built in the 20th century are being replaced by fiber. DefinitionsThe telecommunications industry differentiates between several distinct FTTX configurations.

An aggregation switch is a network device that consolidates traffic from multiple access switches, wireless access points, or other edge devices and forwards it to core switches or routers. By bundling multiple network connections into a single high-bandwidth link, aggregation switches help.

A Layer 3 switch combines the high-speed forwarding capability of a Layer 2 switch with the routing intelligence of a router. It can forward frames based on MAC addresses inside the same local network, and it can also route packets based on IP addresses between different. In this lesson, we examine the network devices that operate at Layer 3 of the OSI model. SVI - Switched virtual interface - Example: Interface VLAN 10 In the example "interface VLAN 10" & "interface VLAN 20" are connected "virtually / conceptually" to the SW-1 IOS that supports routing. So, in effect, they are connected to the "internal router" and act as its actual "interfaces" would. The access layer plays a critical role in connecting end devices—such as computers, printers, IP phones, and wireless access points—to the rest of the enterprise.
