About Us

We’re an independent, family-run company based in Austria. We specialize in delivering smart, custom fiber optic solutions.

Our Story

The NBG Group is an independent, family-run company founded and operated by the Bauer family in Gmünd, Austria.

For more than 25 years, we’ve pioneered innovation in fiber optic technology. We deliver custom cables that perform in any environment, from the telecom industry to the high-temperature and testing oil & gas industry, and from fiber optic sensor technology to home solutions and installations.

The group has over 220 employees with headquarters in Austria and subsidiaries in the Czech Republic, United States, and Germany. An international network of partners enables the group to distribute efficiently worldwide.

Although we’ve grown, we retain our independent nature, and we’re proud of our speed, agility, and innovation.

Our Mission

To connect the world with our high-quality, state-of-the-art fiber optic products and transfer intelligence to critical areas.

NBG Holding GmbH

The bedrock of the NBG Group started in 1996 and serves as a foundation for the development of new subsidiaries. As an actively managed holding company, it offers its subsidiaries a wide range of services, such as human resource management, quality management, IT management, supply chain management, finance management, and marketing. The global NBG network provides support for the development of the subsidiaries.


NBG FIBER began life in 2018, becoming the flagship of the NBG Group. With an annual production capacity of more than 140 tons of high purity glass, equivalent to 5.2 million km of fiberglass, NBG FIBER occupies 1% of the world market. The main product is Fiber Optic Preforms. These are glass fiber cylinders, considered a raw material in the production of glass fiber, which is then ‘drawn’ into glass fiber.


NBG SYSTEMS, founded in 2009, is the hub for international customer requests. Solutions are collected by the subsidiaries and discussed with customers by a dedicated sales team. NBG SYSTEMS also hosts our fiber optic sensor technology. The sensor properties offer multiple possibilities for integration into other applications, such as the measurement of cracks in bridges, tunnels, and high-temperature applications.


NBG TUBE, is the driving force of the NBG Group. Fiber in Metal Tube (FIMT) is an optical fiber sheathed in a protective metal tube. The durable metal tube protects the fragile glass-thin fiber against external influences, including temperature, pressure, and stress. It is particularly relevant in the oil and gas industry, and NBG TUBE has built a reputation for delivering custom solutions to demanding challenges.

NBG Flexkom GmbH

Established in 2010, NBG Flexkom offers services in the field of fiber optic cable installation. These services include the connection of optical fibers to buildings, Fiber to the Home (FTTH) or other structures, Fiber to the X (FTTX), and optical fiber networks in the WAN or MAN area. The procedure for the fixed connection of glass fiber is called splicing, which is one of the core competencies of NBG Flexkom, along with injection technology and measurement technology.

NBG Home GmbH

Since 2018, NBG Home has supported the implementation of fiber optic infrastructures, including the planning of customer-oriented solutions and the trade of components for fiber optic networks. In 2019, the fiber optic division was taken over from EATON and successfully integrated into the NBG Group. The integration extended NBG’s range of fiber optic network technology to include passive connectivity products.


NBG Dimensions was taken over by the NBG Group in 2019, five years after Bernstein Innovation GmbH launched it in 2014, and it is now part of NBG TUBE GmbH. The company engages in 3D printing using the SLS process, where selective laser sintering creates physical objects from plastic powder, layer by layer. Also, fiber optic sensors help design and develop data generating objects.

Safibra s.r.o.

Founded in Prague in 2010, the academic team of Safibra is engaged in the development of hardware for fiber optic sensor technology. Safibra products are used in various projects of the NBG Group and range from sensors to analysis units.

kubator GmbH

The kubator began life in 2014 as a contact point in Waldviertel. Its purpose is to offer innovative personalities a platform to develop business ideas. Besides the support of start-up sector projects, the kubator provides services in marketing and design. The kubator is the marketing department of the NBG Group.
