Our task

Rosenberger OSI stands for Optical Solutions & Infrastructure. We are the European specialists for innovative fiber optic cabling and service solutions for Datacom, Telecom and Industrial. Our products and services are found wherever large amounts of data have to be transferred quickly and safely.

As a team of creative specialists, we meet the challenges of the market on a daily basis. We observe meticulously, think holistically and develop with a high degree of efficiency. We focus on our customers and we react quickly with intensive personal commitment. This secures a permanent and decisive advantage for us and our customers.

Our firm belief

Sustainable growth requires innovations. That’s why we don't simply reinvest our profits in the continuous development of our product portfolio, cutting-edge manufacturing techniques and employee training – we also invest in vital research. Cooperation with universities and research institutions further consolidates our technological leadership in innovation.

As an independent, medium-sized company which is part of the Rosenberger Group, we consciously avoid rigid hierarchies, opting instead for a flexible, process-oriented organisation. This enables us to efficiently combine the performance and innovativeness of a large concern with the speed and increased flexibility of a smaller company.

Our employees' freedom of choice, enjoyment of their work and the dynamism and efficiency of their teamwork are the pillars of our success – and that’s why we consistently promote independent and entrepreneurial thinking and action.

Long-term business relationships are business partnerships. Commitment, honesty and integrity are the foundations of every solid partnership – and Rosenberger OSI places the greatest value on these qualities.

Our future

We will continue to set standards with both our products and our consulting, service and development performances.

We will work constantly to enhance our business processes and strive for a high real net output ratio, thereby creating value for our customers.

Rosenberger OSI will thus continue to pursue its growth strategy as one of Europe’s best-known enterprises in terms of quality and innovation – and as the preferred system supplier of passive transmission technology for Datacom, Telecom and Industrial.
