Coriant says that it has conducted a field trial of its Groove G30 Network Disaggregation Platformwith Latin American fiber-optic and ICT services provider InterNexa. The trial, conducted over active transmission links in Colombia, demonstrated 100G and 200G transmission as well as the use of alien wavelengths over third-party infrastructure.
InterNexa operates a ring-based optical backbone network that runs through Colombia, Ecuador, Peru, Chile, Argentina and Brazil. The company's fiber-optic network footprint of more than 49,000 km of fiber supports service delivery to more than 170 cities and includes connections to five submarine cable systems as well as last-mile and metropolitan fiber networks.
The field trial used Groove G30 platforms with Coriant's CloudWave Optics coherent transport technology. The systems transmitted multiple alien wavelengths, including what Coriant termed "DCI-optimized 200G 16QAM coherent transmission" between Bogotá and Medellín, a distance of 364 km. The trial technicians also demonstrated 100G QPSK transmission between the same two points with a detour to Cali that increased the total transmission distance to approximately 1400 km. This last ring-based demonstration saw the 100G signal transmitted as an alien wavelength through 50-GHz based ROADMs from a third party.
"InterNexa has been a pioneer in adopting open networking and leveraging best-in-class technologies that enable us to efficiently deploy the types of services that our customers require as their connectivity needs evolve," said Gabriel Jaime Vivares, connectivity and data center specialist at InterNexa. "We were pleased with the performance demonstrated in this open transport field trial and impressed with the Groove G30's ultra-high density and unmatched system modularity. Customized service offerings remain one of InterNexa's key differentiators, and the ability to easily and cost-efficiently scale bandwidth in a pay-as-you-grow model is a highly compelling feature."
Coriant has had success with the Groove G30 elsewhere in Latin America, with the system deployed in Telefónica Colombia's network (see "Telefónica Colombia deploys Coriant Groove G30 for 100G data center interconnect services").
