High Quality

A quality management system as a basis for our organisation was introduced immediately after the foundation of Rosenberger OSI in 1991. Since 1995 we have been certified according to EN ISO 9001 with full recognition. We are continually improving our quality management system with the aim of maintaining flexibility with streamlined processes. We have also been certified according to ISO 9001:2008 standards since 2009 and ISO 9001:2015 since 2018.

In addition, the official recognition granted to our manufacturing sites and our business processes by several well-known and important customers has encouraged us to remain faithful to our quality philosophy.

Quality principles

We only buy cables and fibers from leading, high-quality manufacturers. We only use our own connectors or those obtained from well-known, high-quality manufacturers. These connectors meet all current standards and thus correspond to international specifications. All semi-automated assembly processes are carried out and supervised by process and test equipment compliant to the latest standards. We carry out 100% inspections following all critical process stages.

Uncompromising quality:

  • Guaranteed identification and traceability
  • Traceable quality thanks to individual measurement reports
  • Certifications: in accordance with DIN ISO 9001 since 1995 and ISO 14001 since 2008
  • Premium Verification Program (PVP) in the GHMT product and process audits by customers
