Latin American connectivity infrastructure and ICT solutions provider InterNexa and networking solutions vendor Coriant, have announced the successful completion of an open optical transport field trial featuring disaggregated 100G and 200G transmission over third-party optical infrastructure.

The trial was conducted in Colombia earlier this year across active transmission links on InterNexa’s backbone network using Coriant’s Groove G30 Network Disaggregation Platform equipped with Coriant CloudWave Optics coherent transport technology. The testing encompassed multiple alien wavelength use cases including DCI-optimized 200G 16QAM coherent transmission across a direct link between Bogotá and Medellín at a distance of 364 kilometers and ultra-long haul DWDM 100G QPSK transmission between the same cities using an express route through Cali for a total distance of approximately 1,400 kilometers. The latter ring-based alien wavelength use case was implemented across a third-party 50 GHz ROADM-based network architecture.

“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,” says Gabriel Jaime Vivares, connectivity and data center specialist, 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.”

InterNexa operates a ring-based optical backbone infrastructure that supports IP and wholesale transport services throughout South America, with over 49,000 kilometers of optical fiber interconnecting Colombia, Ecuador, Peru, Chile, Argentina and Brazil. The company provides high-availability services across over 170 cities at the national and regional level and offers connections to five submarine cable systems, last mile and metropolitan networks.
