930 940 950 nm Fused Fiber Coupler

  • Wavelength: or Custom Wavelength 950nm 940nm 930nm
  • Fiber Type: Single Mode Fiber
Product Details

The 930 940 950 nm 1×2, 2×2 Single Mode Fused Coupler is built by using fused biconical taper (FBT) technology. It can be used to split the input signal at various ratios with low insertion loss.
