Diamond SA is a Swiss company with a long tradition of specialists in the design, development and manufacturing of connectors for precision optical fibers. With more than thirty years of experience in the field, Diamond SA is a recognized expert and market leader in fiber optic connectivity, offering specific and targeted products for each type of market. As a vertically integrated company, Diamond SA is one of the few manufacturers that has full control over its manufacturing process. High-quality ceramic, metal and plastic components, from the raw material to the end product, are all processed in-house. This system allows Diamond to guarantee that every single component meets all the quality, reliability and performance standards found in Diamond products around the world.

Diamond provides a widely ranging selection of products based on sophisticated technology and the proprietary know-how that we have acquired over many years. They are developed using our experience in manufacturing special fiber-optic interconnecting parts, with the aim of meeting different customer needs.

Diamond technologies are all based on a composite ferrule.
Instead of a full ceramic ferrule, Diamond has opted for a composite ferrule comprised of a zirconia ceramic sleeve and a titanium metal insert.
