Leading backbone network operator in Latin America, InterNexa and Coriant this week announced completion of an open optical transport field trial featuring disaggregated 100G and 200G transmission over third-party optical infrastructure.

InterNexa said that the live field trial showcased its ability to cost-efficiently introduce and scale higher capacity services using open networking concepts while facilitating faster-time-to-market with best-in-class innovations in disaggregated system design.

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.

The open optical transport field trial was conducted in Colombia earlier this year across active transmission links on InterNexa’s backbone network using the Coriant 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.

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.

Lucas Vanagas, MD, South America, Coriant
Our recent collaboration with InterNexa on 100G/200G ULH and DCI alien wavelength use cases for our Groove G30 reinforces Coriant’s commitment to open, disaggregated, and software-driven network evolution.
