Our innovation is built on our extensive experience in the propagation, dispersion, and interaction of light within fiber optics. By combining proprietary chirped FBG fabrication with advanced optical design, Proximion delivers systems and components that perform where conventional systems reach their limits.

Key technologies include:

Our solutions are engineered and verified in our controlled manufacturing facilities, ensuring exceptional reproducibility and long-term stability.

Founded in Sweden in 1998, Proximion has spent more than 25 years advancing the way light is controlled, measured and managed within optical fiber. Since becoming part of Hexatronic Group in 2014, the company has continued to expand its international reach while retaining the specialist engineering culture and manufacturing expertise on which its reputation was built. Today, Proximion serves telecommunications operators, system manufacturers, industrial businesses and research organisations worldwide, and is recognised as a global leader in Fiber Bragg Gratings, FBG technology and optical dispersion management systems, with a growing portfolio of high-precision optical sensors.

Proximion offers the advantage of keeping full control of the product journey. Fiber Bragg Gratings and FBG-based products are designed, manufactured, assembled and verified in-house using advanced UV inscription and proprietary grating-writing techniques. This integrated approach gives Proximion precise control over spectral response, bandwidth, group delay, insertion loss and environmental stability, while supporting rigorous quality assurance, traceability and repeatability.

Its flexible, highly automated manufacturing platform is suitable for both specialist development programmes and scalable volume production. Customers can work with Proximion from initial concept and optical modelling through prototyping, customisation, qualification and serial manufacture. This ability to combine application engineering with dependable production helps shorten development cycles and ensures that each solution performs reliably in its intended environment.

Proximion is more than a component supplier. We are experts in our field, developing bespoke solutions for our customers. We are a technology partner. Our engineering teams work closely with clients to design and optimize photonic systems tailored to their operational goals. From conceptual design to production and validation, we ensure every solution meets exacting specifications and international standards.

Our products are manufactured under rigorous quality control, ensuring stability, linearity, and repeatability even under extreme environmental and mechanical stress. This dedication to precision has earned Proximion the trust of leading global companies and research institutions.
