1480nm1x3/3x3 Single-Mode Fused-Taper Fiber Coupler MCFBT-13-1480-333-L-S2-10-L-FA
Mchlight's single-process fused-taper 1x3/3x3 single-mode fiber coupler (FBT Coupler) couples optical signals in a specially structured fiber coupling region to redistribute optical power. Couplers are available at various wavelengths within 400-2050nm and with different splitting ratios. Fused-taper splitters are widely used in fiber-optic communications, underwater laser communications, fiber lasers, fiber amplifiers and other fields.
