Brazilian telecom services provider Telecall has selected Padtec to supply DWDM gear that supports transmission rates of at least 200G. The communications company will use the gear to upgrade its DWDM networks in the metropolitan region of Rio de Janeiro.
The upgrade includes new fiber-optic links that will add more than 1,000 km to Telelcall’s fiber network and cover such cities as Rio de Janeiro and São Paulo. Padtec says that Telecall also plans to expand its fiber footprint in Brazil's southeast region.
On one of Telecall's optical rings in Rio de Janeiro, Padtec says it has supplied 100- and 200-Gbps transponders and route protection systems. It also has supplied optical time-domain reflectometer (OTDR) capabilities that enable Telecall to monitor, remotely and automatically, the performance of its optical networks. The integrated OTDR function is produced by Padtec using technology developed by VIAVI Solutions. The deployment includes 200 km of lit optical fiber that interconnect the main data centers and land stations in Rio de Janeiro. Padtec also has supplied services for technical support, network monitoring, and management of spare equipment.
The fiber network expansion comes as Telecall sees customer applications that demand bandwidth and speed increases, according to Bruno Kelman Ajuz, Telecall’s vice president. “Padtec is an important ally for the evolution of our optical networks. In addition to the technical quality of its equipment, the installation, operation, and maintenance services offered by the company are a differential that favors the growth of our network infrastructure in a sustainable manner,” he adds.
“The offer of a complete telecommunications services solution, which involves everything from system planning to the installation, operation and maintenance of networks, adds greater strength to our portfolio and to the company,” says Argemiro Sousa, Padtec's business director. “To support that we have more than 40 points of presence today spread across all regions of the country and, also in Argentina and Colombia.”
