1650nm Polarization Maintaining Optical Isolator

  • Wavelength: or Custom Wavelength 1650nm 1625nm
  • Handling Power: or Custom Handling Power 300mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 1650nm Polarization Maintaining (PM) Fiber Isolator is an in-line miro-optic component allows light to be transmitted only in the forward direction while blocking the backward transmittion. It's built with PM Panda fiber and designed to maintain the polarization of the input light with high extinction ratio. The PM isolators are commonly used to protect lasers or amplifiers against back-reflected light. Dual stage isolator means two singe stage isolators are packaged into one compact housing. High power 1650nm PM isolator availible upon request.
