Network Planning2-2Internet Connections

The figure below shows a VDSL Switch-VS2512A and VDSL Splitter-VM2524

providing a broadband data service to a multi-tenant residential or commerc ial

building. In this implementation, fiber optic cable c arries data from a telephone

company’s central office to the building; then the installed telephone copper wires

take the data and deliver it to individual units within that building.

Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A

1000BASE-SX MMF Gigabit link can connect to a site up to 550m away. This allows

end-users in two sites to use the same Internet connection , share server resources,

and communicate with each other.

In the figure below, a 1000BASE-SX port on the bottom VDSL Switch-VS2512A in

the stack in Building 1 is providing 1000 Mbps connectivity to the VDSL

Switch-VS2512A in Building 2.
