Introduction

On November 7, 2025, a groundbreaking achievement was made in data transmission technology as Scala Data Centers, in collaboration with Lightera and Nokia, conducted the first AccuCore HCF™ (Hollow Core Fiber) test in Latin America. This pioneering proof of concept (PoC) was executed at Scala’s Tamboré campus in São Paulo, which is recognized as the largest data center complex across the continent. The remarkable results indicated a 32% reduction in latency compared to traditional optical fibers, marking a significant leap towards faster data transmission, closer to the speed of light.

Innovation at Its Core

Innovation is a critical pillar of Scala Data Centers, and Agostinho Villela, Scala’s Chief Technology Officer (CTO), emphasized the company's commitment to advancing digital performance. The collaboration involved a synergistic effort from all parties:

• - Scala Data Centers provided the infrastructure and testing environment.
• - Lightera supplied the hollow core fiber optic cable, AccuCore HCF™, along with the necessary physical connectivity solutions.
• - Nokia contributed its exemplary 1830 PSI-M optical transmission platform tailored for data center interconnections.
• - MagicComp played a vital role in physically installing and commissioning the fiber cable, demonstrating their expertise.
• - VIAVI Solutions equipped the project with its advanced optical testing and certification tools, including the OneAdvisor 800 Transport module.

What sets hollow core fiber apart is its innovative design: unlike conventional fibers that transmit light through a solid silica core, hollow core fibers guide light through a central air core. This structural difference enables significantly accelerated data travel speeds.

A Leap Towards Enhanced Connectivity

Helio José Durigan, Senior Vice President for LATAM and EMEA regions at Lightera, articulated the advantages of this cutting-edge technology. He noted that hollow core fibers provide near-optimal transmission speeds and improved energy efficiency. To put it in perspective, São Paulo appears to be digitally 32% closer to Vitória, Espírito Santo, considerably benefiting latency-sensitive applications like cloud computing, financial processing, and gaming.

Furthermore, the reduced latency is a game-changer for high-frequency financial applications, machine learning model training, and other workloads that rely heavily on rapid data transfer. The test conducted revealed not only a 32% latency improvement but also emphasized the capability of data centers to optimize internal communication. As future developments in this technology progress, there are plans to tackle the current range limitations, aiming eventually for metropolitan and long-distance connections.

Future Prospects

With the success of this proof of concept, Scala Data Centers, Lightera, and Nokia are now considering pathways for production-scale deployments. The focus is on applications requiring ultra-low latency and handling high data volumes, which aligns seamlessly with Scala's vision of developing next-generation infrastructure designed for artificial intelligence challenges.

Conclusion

This collaboration among Scala Data Centers, Lightera, and Nokia signifies a step forward in data transmission infrastructure in Latin America. As the companies set their sights on further innovations, the development of hollow core fiber technology is poised to revolutionize the landscape of digital connectivity. By moving towards more expansive applications such as intra-site and inter-campus scenarios, this groundbreaking technology could redefine the future of data centers and the entire digital ecosystem.
