Coriant, InterNexa complete Latam capacity trial

Coriant and InterNexa have successfully completed a field trial featuring disaggregated 100G and 200G transmission over third-party optical infrastructure.


The open optical transport live 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’s CloudWave Optics coherent transport technology.

It showcased InterNexa’s 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 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 centre 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. Customised 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.” 

The testing encompassed multiple alien wavelength use cases, including DCI-optimised 200G 16QAM coherent transmission across a direct link between Bogotá and Medellín at a distance of 364km and ultra-long haul DWDM 100G QPSK transmission between the same cities using an express route through Cali for a total distance of approximately 1,400km. The latter ring-based alien wavelength use case was implemented across a third-party, 50GHz ROADM-based network architecture. 

Lucas Vanagas, managing director of South America at Coriant, added: “We continue to advance the capabilities of this industry-leading disaggregation platform to ensure our Latin America customers are positioned for success both today and well into the future. Recent enhancements, for example, provide a seamless and cost-effective path to higher interconnect speeds such as 400G client side and 600G line side transmission – without the need for forklift upgrades.”

InterNexa operates a ring-based optical backbone infrastructure that supports IP and wholesale transport services throughout South America, with over 49,000km of optical fibre 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.
