High-power interconnect solutions

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.  

Single-mode power solution technology

Diamond offers dedicated single-mode connectors that support higher optical power at fiber-to-fiber or air-to-fiber transitions. To reduce the risk of laser-induced damage or failures due to thermomechanical effects, different techniques are applied to increase the spot size and consequently decrease the optical power density at the interface. These techniques are also available for polarization maintaining fibers, and ideal for precise optical fluence engineering on butt-coupled Semiconductor Saturable Absorber Mirrors (SESAMs) in ultrafast mode-locked fiber lasers with high pulse energies.

Multimode power solutions

Diamond has also developed industrialised 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 connector-to-connector solutions for reliable transmission of several hundred watts in multimode fibers (ex. E-2000 PSm) are offered.
