Certified quality management

Quality creates trust. And because this is the case, we place the highest demands on quality and also have it ISO-certified. And what's more: as a pioneer in the industry, our quality management is always up to date. For you, this means that our products meet the most demanding requirements and expectations in all areas of performance.

More than just standard: We are not only certified according to ISO 9001:2015 and ISO 14001:2015. In 2002, we were the first company in Germany to receive the TL-9000 standard, a special extension of the ISO-9001:2008 certification for the telecommunications industry. This ensures quality, reliability and sustainability of your investments.
