This VDSL switch provides Internet connections of up to 100 Mbps
symmetric, or an asymmetric 100 Mbps downstream and 50 Mbps
upstream over 200 meters. Cable distances also can run up to 1.5 km at
lower transmission rates. Installation is extremely economical for
multiple-tenant dwellings such as apartment buildings, hotels or school
dormitories, as well as commercial buildings.
VDSL provides multiple-user access to the Internet with benefits
including:
•
Internet services such as e-mail over faster connections than currently
possible with other options such as cable modem or ADSL
• Multimedia applications such as video and virtual gaming made
available to the broader public for the first time
• Access to corporate intranets at speeds close to that available in the
office
• Both local network applications and Internet services are supported
for commercial environments
Internet Connections
The figure below shows a VDSL switch 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.
