Sipartech strengthens its long-haul network infrastructure to 400G+ and accelerates links to top global internet hubs in Europe

Sipartech announces immediate availability of 400G+ spectrum and wavelength offers across its network, at the same time as deploying new long-haul routes in Europe.

Tests were successfully conducted earlier this year to ensure full interoperability between the equipment of all major vendors. In addition, the energy savings and carbon footprint reductions measured are in line with Sipartech sustainability goals.

Sipartech’s new 400G+ solutions meet the growing demands of operators, data centers and enterprises for high bandwidth between global internet hubs in Europe. These solutions offer high speed data transport solutions with some of the highest security, redundancy and capacity requirements on the market. They can be delivered within four weeks to 214 data centers in Europe.

The Sipartech long-haul network is designed with a unique three-way topology that interconnects its metropolitan dark fiber networks. Each route lands in a separate data center, with several possibilities for further extensions to a wide portfolio of data centers. Today, 214 data centers can be activated with 400G+, thanks to the capillarity of Sipartech’s metropolitan networks. This will grow to around 350 data centers in Europe, as indicated in the Sipartech 2023-2025 roadmap.

“We are investing in the extension and diversification of our long-haul network as well as in its continuous and sustainable development, as part of our 2023-2025 strategic plan. We are increasing our presence in Europe, offering state-of-the-art, efficient and tailor-made solutions for our customers in line with our sustainability goals. Meeting our customers’ requirements for performance and energy efficiency is our focus and commitment” says Julien Santina, founder and CEO of Sipartech.
