The QBH fiber optic cable is the no. 1 fiber interface for industrial high-power fiber lasers. It's a well proven standard compatible with most available tools worldwide. For lower power systems and applica ions an air-cooled. Mechanical receiver for QBH (RQB, HLC-8, LC-8, LLK-Q) fiber optic cables. Technologies incorporated in the products include cladding mode stripping, water cooling, proteQBH fiber adapters are used for mounting fibers with QBH termination to high power sensors L1500W-BB-50, L1500W-LP2-50, 5000W-BB-50 and 5000W-LP2-50. This can be used for extending the range of an existing fiber cable installation, to change the beam quality by connecting a larger fiber core diamete, or to connect different mechanical fiber cable interfaces together.
