Harnessing Quantum Technology with Fiber Optics Expertise

At Diamond SA, we are at the forefront of quantum technology in fiber optics. With over 40 years of expertise as a fiber optic pioneer, we have built a reputation for producing high quality fiber optic components. Our proprietary Active Core Alignment (ACA) technology, which perfectly centers fiber cores, enables us to manufacture exceptionally precise connectors.

One of our key competencies is achieving remarkably low insertion loss, which is critical for quantum applications using fiber optics. Our insertion loss can be as low as 0.05dB*, exceeding industry standards. This level of performance is made possible by our deep understanding of fiber optic technology and our commitment to delivering superior quality.

For quantum applications, we offer a range of relevant technologies that address specific needs. Our Power Solution is designed for high power applications, ensuring reliable performance under demanding conditions. We also specialize in polarization maintaining, enabling precise control and manipulation of light polarization in quantum systems. When it comes to high and very low temperature environments, such as cryogenic applications, our connectors are designed to withstand extreme conditions while maintaining optimum performance. Our technologies perform - exactly where you need them to.

In addition to our expertise in quantum technology, Diamond SA offers a comprehensive range of multi-channel fiber optic components. These components are designed to facilitate the transmission of multiple signals simultaneously, providing enhanced scalability and efficiency in quantum applications.
