1550nm PM Filter Coupler

  • Wavelength: or Custom Wavelength 1550nm 1480nm 1310nm
  • Handling Power: or Custom Handling Power 300mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 1550nm 1×2, 2×2 Polarization Maintaining (PM) Filter Coupler is built by using thin-film filter technology. It can be used to split the input signal at various ratios while preserving the polarization with high extinction ratio.
