Brazilian telco Transit Telecom has completed work on a section of its fibre-optic ring network, connecting the state of Sao Paulo to the country’s capital. The project comprised 400km of cable using dense wavelength division multiplexing (DWDM) technology and will be used to provide high speed internet services to the cities of Sorocaba and Campinas. The optical cables transit eight other cities where Transit Telecom previously had no points of presence (PoP). Overall, the telco’s fibre has a total capacity of 10Gbps and will offer commercial broadband at rates of between 1Mbps to 150Mbps, over LAN-to-LAN and VPN networks.
