High Power QBH Fiber Jumper: Core Transmission Component for Industrial Laser Welding
High Power QBH Fiber Jumpers, serving as critical optical connection components in industrial laser welding systems, directly determine laser energy transmission efficiency and processing precision. This category of high-power fiber jumpers employs a unique QBH connector interface design featuring 8° angled physical contact (APC connectors) end faces and an active cooling structure, capable of stably transmitting kilowatt-level (1-6kW) continuous laser power. They have become indispensable core optical path components in laser processing equipment.
Regarding performance, high-power QBH jumpers possess three core technical advantages: First, the use of large-core (400-600μm) specialty doped fibers combined with a low numerical aperture design achieves laser transmission efficiency exceeding 95%. Second, a dual-layer metal armored structure integrated with water-cooling channels effectively manages thermal effects generated by high-power lasers, ensuring end-face temperatures remain below 80°C. Third, end faces utilize ultra-precision polished APC connectors, controlling return loss below -60dB to prevent laser resonator instability.
Typical application scenarios for such high-power laser transmission components include high-end manufacturing fields such as new energy vehicle power battery welding, shipbuilding thick-plate laser welding, and aerospace precision component processing. In actual industrial environments, they can withstand over 10^6 mating cycles, with power fluctuation below ±3% under vibration, meeting ISO 11554 industrial laser standards. Compared to traditional QD or QCS interfaces, the QBH interface demonstrates clear advantages in cooling efficiency and connection stability, making it the standard configuration for laser systems above 6kW.
With the deepening advancement of Industry 4.0, high-power fiber laser welding is evolving towards intelligence and flexibility. New-generation QBH jumpers are beginning to integrate fiber Bragg grating (FBG) temperature sensing and power monitoring functions, working in conjunction with smart manufacturing systems to achieve real-time closed-loop control of laser parameters. Looking forward, with the commercialization of 20kW-class ultra-high-power laser systems, QBH jumpers utilizing diamond-coated end faces and micro-channel cooling will represent the next technological frontier in laser equipment.
