2000nm Fiber Optic Coupler

  • Wavelength: or Custom Wavelength 2000nm
  • Handling Power: 1W
  • Fiber Type: Single Mode Fiber
Product Details

The 2000nm (2 micron, 2μm) 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.
