1950nm Polarization Maintaining Fused Couplers Splitters

  • Wavelength: 1950nm 2000nm 2050nm or Custom Wavelength
  • Handling Power: 2W or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 1950nm (2 micron, 2μm) 1×2, 2×2 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. High power handling up to 2W as normal and up to 5W or higher is available upon request.

Note  
*  Test at center wavelength without connector. For devices with connectors, EL will be 0.3dB higher, and PER will be 2dB lower.
*  Both axis operating.
*  The PM fiber and the connector key are aligned to the slow axis.
