532,632,638,680,780nm Single Mode Visible Wavelength Couplers

  • Wavelength: 780nm or Custom Wavelength 632nm 532nm 488nm
  • Fiber Type: Single Mode Fiber
Product Details

  The 530,532,590,630,632,638,650,680,690,780 nm 1×2, 2×2 Single Mode Visible Wavelength Fused Couplers are built by using fused biconical taper (FBT) technology. It can be used to split the input signal at various ratios with low insertion loss.
