1950nm 2000nm 2x2 Fiber Coupler Single-Mode Tapered Optical Beam Splitter

1950nm 2000nm 2×2 Fiber Coupler Single-Mode Tapered Optical Beam Splitter Fused tapered single-mode fiber optic couplers (FBTCouplers) enable optical signals transmitted in optical fibers to couple in a specially structured coupling region, redistributing optical power. Couplers with various wavelengths and splitting ratios within the 400-2050nm range can be manufactured. FBTCouplers are widely used in optical fiber communication, underwater laser communication, fiber lasers, fiber amplifiers, and other fields.
