1×3 Monolithic Fused Polarization Maintaining Couplers

  • Wavelength: 1064nm 1310nm 1450nm 1480nm 1550nm 1590nm 1625nm
  • Handling Power: 2W or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 1310, 1480 or 1550nm 1×3 Monolithic Fused Polarization Maintaining (PM) Coupler is built by using fused biconical taper (FBT) technology. It can be used to split the input signal at 33:33:33 ratio while preserving the polarization with high extinction ratio. High power handling up to 2W.

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