Description
980nm 1×3 3×3 PM Fiber Fused Coupler
980nm 1×3 3×3 PM Fiber Fused Coupler is built with fused biconical taper (FBT) technology, it can be used in split the optical signal power into 3 parts with even or various coupling ratio and keep the polarization maintaining, it’s widely applied in Quantum Communication and fiber optic diffraction field. High power version upt o 20W CW is available.
