Started From a Lab

ESTEL started in the lab, driven by a passion for telecom and datacom technologies. That spirit of experimentation still guides us today. Our team brings together researchers and engineers who transform advanced optical concepts into reliable, manufacturable transceivers used in real‑world networks.

Enhanced Testing

Every transceiver is designed for efficiency, stability and low power consumption. Before leaving our European facilities, each module undergoes comprehensive functional and optical testing ensuring consistent performance in demanding network environments.

Why Estel as a partner

European manufacturing for secure, traceable supply

All ESTEL transceivers are designed and produced in Europe, ensuring full control over quality and compliance. This local production model gives you a stable, politically secure supply chain with complete traceability.

QSFP28 / QSFP-DD / OSFP / ODM modules for modern networks

We manufacture high-performance 100G, 400G and 800G optical transceivers for data centers, metro transport and long-haul links. Beyond our standard portfolio, we develop custom ODM solutions for defense, space and cybersecurity applications, tailored to each project’s performance, integration and operating requirements.

Automated production consistent, repeatable quality

Our manufacturing lines rely on advanced automation to eliminate variability and improve precision. This ensures every module performs consistently, simplifying your qualification process and reducing field failures.
