The DWDM network will span 6,500 kilometers in the central-east region of Brazil and will connect the major cities in Brazil, including Brasilia, Sao Paulo, Rio de Janeiro, Belo Horizonte and Uberlandia. The deployment includes the XDM-4000, a core optical system for regional networks. In addition, Lightscape Networks' XDM-1000 and XDM-500 will be deployed in several metropolitan parts of the network, enabling future expansion to SDH/SONET in the same network. The initial phase of the contract is for $5 million, with the potential for further network expansion in the near future.
