Description
1150nm 1×3 3×3 PM Fiber Fused Coupler
1150nm 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 up to 20W CW is available.
