Quality & Environment

Products certified and tested to the very highest quality requirements

The quality and environmental protection management systems used at j-fiber GmbH and j-plasma GmbH are certified to DIN ISO 9001 and ISO 14001.

We have implemented a company-wide management system (IMS) that works continuously to identify potential for optimization within the company. External and internal audits are used to ensure that j-fiber Group continues to meet its high standards for environmental protection and quality.

Manufacturing to demanding U.S. MIL-STD-790 standard

In April 2006, the US Defense Supply Center, Columbus (DSSC, a unit within the U.S. Defense Logistics Agency) conducted detailed audits to certify j-fiber’s production facilities to the MIL-STD-790 standard; j-fiber was recertified in 2013. This certification states that the j-fiber production facilities make high-quality optical fibers that meet the rigorous standards for manufacturing, documentation, testing, and process flows as demanded by the U.S. Government. Accordingly, the fibers offer a maximum level of safety, reliability, and conformity to standards, as required by military and aerospace applications. As an authorized supplier, j-fiber is qualified to supply radiation-hard multimode and singlemode fibers conforming to the MIL-PRF 49291 specification.

Sustainability and intelligent ecological management

j-fiber was one of the first fiber manufacturers to implement company-wide production processes that are both ‘green’ and safe – and these are also checked along the supply chain. Our integrated ecological management and systematic recycling (recycling rate of 98.2%) allows us to run complex chemical processes while conserving resources and protecting the environment. j-fiber has run an environmental management system in line with the rigorous EMAS rules since 1998 and conducts regular audits to prove compliance.
