1950nm PM Filter Coupler

  • Wavelength: 1950nm 2000nm 2050nm or Custom Wavelength
  • Handling Power: 300mW or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 1950nm (2 micron, 2μm) 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.
