7×1 Pump Combiner Low Insertion Loss Optical Fiber Combiner
The 7×1 multi-mode pump combiner is designed for high-power applications, combining 7-channel pump energy into one optical fiber for transmission. The output fiber can be an energy-transmitting fiber, just for energy synthesis; it can also be an LMA double-clad fiber, combined with active fiber, fiber grating and other devices to form various types of fiber amplifiers. The device has high pump absorption efficiency, low insertion loss, can withstand power up to 50W per arm, and has stable and reliable performance.
