QBH Fiber Optic Cable
The QBH Fiber Optic Cable is the standard fiber for high-power lasers. It is designed to withstand extreme levels of back-reflection from the workpiece; the internally water-cooled connectors absorb back-reflection up to 5 kW. Due to the conical guiding interface, installation is easy and accurate. Plug and play within 10 µm.
