Polarization Maintaining CWDM

  • Wavelength: 1310nm 1550nm 1590nm S+C+L Band or Custom Wavelength
  • Handling Power: 500mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The Polarization Maintaining Coarse Wavelength Division Mulitplexer (PM CWDM) is based on thin-film filter technology compliant to ITU standard. It provides single channel add or drop function, or it can be cascaded into sequence for multi-channel applications in CWDM systems. 1x4, 1x8, 1x16 PM CWDM Modules are available upon request.
