Ciena Corp Powers Trans Americas Fiber System's TAM-1 Submarine Cable with Next-Gen Optical Solutions

On October 21, 2025, Trans Americas Fiber System (TAFS) announced a significant milestone in digital infrastructure with the deployment of its new TAM-1 subsea cable system, set to revolutionize connectivity throughout the Americas. This cutting-edge network is designed to deliver exceptional capacity, scalability, and resiliency, marking the first scalable, neutral fiber system to connect Central America and the Caribbean directly to the United States in decades.

The TAM-1 cable system boasts an impressive total capacity of over 650 terabits per second (Tbps), utilizing 24 fiber pairs for southbound connections and 12 for northbound. TAFS has partnered with Ciena Corp (NYSE: CIEN) to incorporate high-capacity optical solutions, including the advanced GeoMesh Extreme powered by WaveLogic 6 Extreme and the 6500 Reconfigurable Line System (RLS). This robust open architecture is designed for spectrum sharing and fluid scalability, enabling operators to expand their networks seamlessly as demand for connectivity continues to rise.

Julio Bran, CEO of TAFS, stated, "At TAFS, we are leading a new generation of fluid connectivity for the Americas, one that redefines how networks are built, accessed, and scaled. As we pursue this vision, we are choosing Ciena — not only for their technology but for their alignment with our mission to deliver flexible, efficient, and future-ready digital infrastructure. TAM-1 is designed to disrupt the status quo, and together we are setting a new standard for connectivity in the region."

The TAM-1 system spans 7,200 kilometers and features two diverse subsea routes, significantly enhancing resiliency while providing low-latency connectivity crucial for various critical applications. Its programmable and automated design is specifically engineered to meet the bandwidth requirements of emerging technologies such as artificial intelligence (AI), cloud computing, 5G, edge computing, streaming services, and enterprise applications. This positions TAM-1 as a substantial upgrade over legacy systems currently servicing the region.

Ciena's Vice President of Global Submarine Solutions, Thomas Soerensen, commented, "Trans Americas Fiber System’s TAM-1 cable system is designed to provide seamless and reliable connectivity across the trans-Americas region. Leveraging Ciena’s GeoMesh solution and optical networking expertise, TAM-1 will be poised to power the region’s surging bandwidth demands driven by cloud, video streaming, AI, and more."

As TAFS rolls out the TAM-1 system, the northern route is expected to be Ready for Service (RFS) in the fourth quarter of 2025, with the southern route following suit in the first quarter of 2026. This ambitious project not only promises to enhance connectivity but also aims to transform how operators procure and utilize bandwidth through its innovative and scalable architecture.

The deployment of the TAM-1 submarine cable system underscores a pivotal moment in the telecommunications landscape of the Americas, positioning TAFS and Ciena at the forefront of digital transformation. By facilitating unprecedented capacity and agility in network design, the TAM-1 system is set to reshape the connectivity paradigm for businesses and consumers alike.

With the TAM-1 submarine cable system, Trans Americas Fiber System and Ciena are embarking on a groundbreaking journey towards a more connected future for the Americas. As demand for high-speed connectivity escalates, initiatives like TAM-1 will be essential in meeting the challenges of tomorrow’s digital landscape, ensuring that the region not only keeps pace but leads in global connectivity advancements.
