Internet Connections

The figure below shows a VDSL Switch-VS2512A and VDSL Splitter-VM2524
providing a broadband data service to a multi-tenant residential or commercial
building. In this implementation, fiber optic cable carries 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.
