(N+1)*1 High Pump Efficiency Multi-Mode Pump Combiner
The pump combinator mainly pumps multiple photosynthetic beams into a single optical fiber for output, Mainly used to increase the pump power (also known as multi-mode - multi-mode fiber beam splitter). (N+1) 1 The optical fiber in the center of the fiber splitter is a signal optical fiber. During the fabrication process, N multimode fibers must be arranged around the signal fiber in close symmetry, and the signal fiber in the middle is used for the signal light input. The fiber beam splitters are mainly used for fiber amplifiers.
