488 532 632nm Visible Wavelength PM Fused Couplers

  • Wavelength: 632nm 532nm 488nm
  • Handling Power: or Custom Handling Power 100mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 488 532 632 nm 1×2, 2×2 Visible Wavelength Fused Polarization Maintaining (PM) Fiber Optic Coupler is built by using fused biconical taper (FBT) 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 each connector added, EL will be max. 1.0dB higher, and PER will be 2dB lower.  
  *  Available for fast axis operating or slow axis operating. If you need both axis operating please contact us.  
  *  Operating on both fast and slow axis. Connector key is aligned to slow axis.
