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.
Figure 2-1. Internet Connections
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.
