1120nm Polarization Maintaining Optical Isolator

  • Wavelength: 1120nm or Custom Wavelength
  • Handling Power: 300mW or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 1120nm Polarization Maintaining (PM) Optical 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. High power 1120nm PM isolator availible upon request.
