The Company

We’re well connected

Our Mission

Our mission is to manufacture high-precision, high-performance fiber optic components and assemblies that exceed our customer expectations. 

Striving for Progress

The history of Diamond SA began in 1958, with the precision machining of ultra-hard materials, such as ruby, sapphire, tungsten carbide and diamond, all used in the production of high-precision technical components.  The experience gained in these endeavors formed the basis of the company’s expertise in precision machining and volume production, expertise which Diamond has systematically expanded and perfected over the years. In 1979, the demand for diversification led Diamond into the exciting, growth-intensive field of fiber optics, where the company quickly established itself as an internationally renowned innovator within the industry.

Our Products

We assemble our components to create finished products and a wide range of cable assemblies. We are able to manufacture and prefabricate products using different optical fibers and ferrule technologies according to customer requirements. Diamond uses a unique two-component connector ferrule, comprising of a high-precision ceramic ferrule with a titanium insert. This unique ferrule, together with Diamond’s patented Active Core Alignment process, precisely aligns the fiber core to the axis of the ferrule to reduce Insertion Loss values to a minimum. This special process enables Diamond to ensure high-performance in all its products.

In-House Component Manufacturing

From raw material to high-tech components

Our Quality

We can all agree that quality is of the utmost importance in fiber optics. In a transmission medium thinner than a human hair, where tolerances are measured in microns and nanometers, absolute precision is paramount. Since 1994, our products and processes are governed by a quality management system certified to ISO 9001 since 1994. Diamond suppliers are also required to comply with QMS, ensuring continuous quality from raw material to finished product. In addition, our testing laboratory is internationally accredited to ISO / IEC 17025 and certified by the Swiss Accreditation Service (SAS).
