The Alien Wavelength system, provided by Padtec to the Colombian carrier of carriers, allows data traffic at 300 Gbps in that region.
To increase its service offerings and as a result to increase its customer base in Brazil, this is the main objective of InterNexa, a Colombian telecommunications operator that operates an extensive optical fiber network in Latin America and the United States. To meet this objective, InterNexa has been investing in increasing the transmission capacity of its DWDM (Dense Wavelength Division Multiplexing) networks between the Brazilian states of Sao Paulo and Rio de Janeiro.
To meet the increased demand for high transmission rates between two of the most important metropolitan regions in the country, InterNexa Brazil used Padtec systems to upgrade network interfaces in its legacy optical network, using alien wavelengths at transmission rates of 300 Gbps. In total, the optical channels lit by Padtec for the operator cover up to 650 kilometers, which connect main data centers and submarine stations in the capitals of Rio de Janeiro and Sao Paulo.
Carlos Gaviria, InterNexa Brazil’s CEO, says that the increasing market demand for bandwidth and speed requires an constant investment in high capacity infrastructure. “As it operates in a sector that is technologicaly driven, InterNexa is always researching and analyzing the most updated technologies available, in order to choose the one that best meets market demands and with the best cost and performance ratio”, he explains. “Thus, our customers can rely on us for their infrastructure needs and focus their resources on quality assurance at the edge, for the consumer”, adds the executive.
To active Internexa’s new route, Padtec supplied state-of-the-art DWDM systems with 1.2 Tbps transponders, optical amplifiers and route protection systems. One of the highlights of the project is the protection route in the optical network of InterNexa. This route is a total distance of 1,500 kilometers in length, connecting Rio de Janeiro and São Paulo via Belo Horizonte. The use of this new generation of transponders eliminated the need to regenerate the signal along the route, contributing to the reduction of CAPEX and OPEX and maintenance costs for locations in the operator’s long-distance optical system.
In line with international technology trends in optical transport for the datacenter segment, the new line of 1.2 Tbps transponders (up to 600 Gbps per network interface) of Padtec’s LightPad i6400G platform, combine high data transmission rate with lower cost per transmitted bit. “One of the technical innovations of this generation of transponders is in the mechanics. Only 1RU high and 300 mm deep, this unit supports rack mounting in both datacenters and telecom locations”, says Argemiro Sousa, Padtec’s Business Director and Acting President. “Another of the technical innovations of this generation of transponders is the more flexible network interfaces that allow better adaptation of the optical channels to meet the increasing demands for network performance and expansion”, add Argemiro.
