Beyond the Rack: Sovereign AI via European Pluggables

Author: Magnus Olson, CTO, Estel Collection: 2026-OCP-EMEA-Summit-Photonics

Summary

Magnus Olson, CTO of Estel — a Belgian-headquartered startup founded roughly two years prior to the talk — presents the case for a European-sovereign optical transceiver manufacturing ecosystem. He argues that three converging forces have created the market: geopolitical pressure to eliminate dependence on Chinese-manufactured optical modules; rapidly growing demand from data centers, AI/HPC deployments, and dual-use/military customers who explicitly require locally sourced transceivers; and emerging EU regulatory leverage via the Cyber Resilience Act (CRA), which reaches full application by end of 2027 and is expected to severely restrict Chinese vendors' ability to sell on the European market. Estel positions itself as the only European transceiver manufacturer at the time of the talk, operating its first fab in Belgium for hermetic optics and 100G Telco/dual-use applications, with a second fab under construction in Malaga, Spain (targeting mass production 1H 2027) for non-hermetic, chip-on-board, 800G/1.6T+ data center and HPC modules, and a third fab planned in Texas (also 1H 2027) for US customers with equivalent sovereignty requirements.

The bulk of the talk maps the European photonics value chain against a two-axis framework (products vs. fabs/foundries) and finds significant strength in lasers and photonic integrated circuits (PICs) — 7 laser product companies, 6 laser fabs, 10 PIC product companies, 9 PIC fabs identified — while highlighting critical gaps: zero DSP ASIC design or manufacture in Europe (all US design, all Asian manufacture), zero high-volume photonic packaging capacity in Europe (all Asian), and zero advanced PCB (UHDI/mSAP) fabrication in Europe (all Asian). Estel's technical approach deliberately avoids touching these gap segments and instead builds at the assembly and system-integration layer, using 100% automation to achieve cost parity with Asian alternatives. As a concrete example of this supply chain in practice, Olson describes the 800G DR8 OSFP LPO module developed under the EU-funded Net4Exa project for Eviden (Bull/Atos HPC), which uses PICs from the STM foundry in France, quantum dot lasers from Innolume in Germany, and PCB assembly (PBA) by Kitron in Sweden, with first alpha build and bring-up targeted for June 2026.
