Diamond SA
Swiss fiber optic connectors and assemblies since 1980
About Diamond
Diamond SA is a Swiss manufacturer of fiber optic solutions for high-performance applications, based in Losone. The company has worked on fiber optic connectivity since 1980 and says it combines Swiss engineering with in-house manufacturing, from concept through to finished assemblies. Its customers are in aerospace, photonics, quantum technology and semiconductor technology, among other fields.
The company stresses vertical integration. Its capabilities cover ceramic powder injection and compression moulding, metal machining and plastic moulding, followed by cleanroom manufacturing and high-purity cleaning, so that most of the work on a connector takes place under one roof.
