Telebras has completed the fiber-optic rings in the Northeast and Southeast of Brazil, expanding its telecommunications network by over 8,900 kilometers. In doing so, the company's backbone extends 25,000 km across the country. The metropolitan areas of São Paulo, Rio de Janeiro, Vitória and Belo Horizonte have now become part of the Telebras national network.

The network will also be used during the Confederations Cup to provide FIFA with image and sound broadcast services for high definition television (HDTV) in order to ensure global transmission of the games. For this purpose, links totaling 20 Gbps will be used to connect all stadiums participating in the event to the International Broadcast Coordination Center (IBCC), located in the state capital, Belo Horizonte.

Telebras will utilize DWDM (dense wavelength division multiplexing) technology to illuminate fibers with equipment developed in the country.

"Last week, we conducted tests on our network with the company contracted by FIFA to broadcast the video signal for matches in the Confederations Cup and the World Cup, and the result was excellent," said Caio Bonilha, President of Telebras.
