Description
810nm High Power 1×2 2×2 PM Fiber Fused Coupler
810nm High Power 1×2 2×2 PM Fiber Fused Coupler is built with fused biconical taper (FBT) technology, it can be used in split the optical signal power into two parts with even or various coupling ratio and keep the polarization maintaining, it’s widely applied in Quantum Communication, fiber optic sensor, and fiber optic diffraction field. The optical power can be up to 20W CW.
