  • Handling Power: 500mW or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 1950/1550nm 1950/1570nm Polarization Maintaining (PM) Filter Wavelength Division Mulitplexer (WDM) is based on thin-film filter technology. It provides wavelength division multiplexing while maintaining signal polarization with high extinction ratio. High power available upon request.
