810nm PM Filter Coupler

  • Wavelength: or Custom Wavelength 810nm
  • Handling Power: or Custom Handling Power 300mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 810nm 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.

  Note    
  *  Test at center wavelength without connector. For devices with connectors, EL will be 0.2dB higher, and PER will be 2dB lower.  
  *  The PM fiber and the connector key are aligned to the slow axis.
