Background
Customer Name: Nebius
Industry: AI Service Provider
Country: Netherlands
Company Size: 1,000+ employees
Customer Voice: We are a European company providing AI builders with infrastructure and services. Our core business is an AI-centric cloud platform. Due to service expansion, we need to build a new R&D hub, which requires many optics to set the fractures and interconnect the hub with other hubs over a WAN of more than 100 kilometers.
Challenges
Nebius faced the challenge of rapidly expanding its infrastructure to accommodate a new R&D hub. It is critical to establish reliable and high-performance connections between multiple R&D centers across a wide area network (WAN) with high-quality optics.
Solutions

To address Nebius’s needs, QSFPTEK provides custom solutions tailored to their specific requirements.
Given that the client requires connection over 100km, QSFPTEK recommended the QSFPTEK 1G SFP modules, particularly the QT-SFP-03150D 1000BASE SFP modules, which can achieve direct connections of up to 150 km using single-mode duplex optical cables. For such a long-haul transmission, this solution saved the trouble of adding extra WDM OTN equipment compared to WDM solutions. It ensured Nebius interconnects its new R&D hub with existing hubs, providing the necessary bandwidth and reliability.
Also, QSFPTEK provides free technical support for the client throughout the process, especially installation assistance. The client can rest assured of wholesale process support. In laboratory simulation scenarios, all modules undergo rigorous compatibility and performance testing to ensure that product performance meets actual needs.
