High-power interconnect solutions up to 16W in Single-mode optical fiber

14 Sep 2021

The DIAMOND Power Solution (PS) connector series is designed for high-power fiber optic transmission on small core fibers to ensure high reliability. Our unique expanded beam technology reduces the beam power density at the connector interface, allowing connections with an incredibly low failure rate. Simultaneously, these connectors assure high transmission efficiency, thereby, minimizing Insertion Loss and maximizing Return Loss. By introducing new manufacturing techniques, we are now able to provide an improved PS+ solution offering approximately 36 μm SM expanded Mode Field Diameter (MFD). This results in the ability to provide high-power transmission of up to 16W within SM optical connectors.

Multimode Power Solutions

DIAMOND has also developed industrialized custom ferrules for direct light injection into multimode fibers. These AR-coated ferrules can be integrated into high-power diode modules and withstand free-space coupling of >100W. The heat extraction is made possible through engineered mode strippers.

In addition, DIAMOND offers connector-to-connector solutions for reliable transmission of several hundred watts in multimode fibers (ex. E-2000 PSm).

Laser modules with direct fiber plugs through Diamond connectors and adapters

Laser diodes with direct connector plugs eliminate the need for splicing and presents unquestionable advantages in terms of modularity and ease of replacement. However, an extreme positioning precision is mandatory to assure excellent optical coupling, also when switching connectors in the integrated mating adapter.

The rigorous quality control on DIAMOND products ensures reproducibility of the fiber core position within ± 1 µm after mating and de-mating of different connectors, combining unique features of mechanical precision and high-power handling.


DIAMOND is a Swiss company with a long tradition of specializing in the design, development and manufacturing of connectors for precision optical fibers. With many years of experience, DIAMOND is a recognized as the expert and market leader in fiber optic connectivity, offering specific and targeted products for a wide range of applications.

DIAMOND is one of the few manufacturers that has full control over its vertically integrated manufacturing process. High-quality ceramic, metal, and plastic components, from raw material to the end product, are all processed in-house. This allows DIAMOND to guarantee that every single component meets all quality, reliability and performance standards found in DIAMOND products around the world.
