PETAH TIKVA, Israel, July 15 -- Companhia de Telecomunicacoes do Brasil Central (CTBC Telecom), a Brazilian telecom carrier, has selected Lightscape Networks' XDM converged optical networking platform for deployment in its Dense Wave Division Multiplexing (DWDM) network backbone. 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.
