2000nm Polarization Maintaining Optical Circulator

  • Wavelength: 1950nm 2000nm 2050nm or Custom Wavelength
  • Handling Power: 500mW 1W 2W
Product Details

  The 3 port 2000nm (2 micron, 2μm) polarization maintaining (PM) optical circulator is a fiber optic componet built with PM panda fiber.  It allows light to be transmitted in only one direction while blocking the opposite transmttion, it's light path is port 1 to port 2, and port 2 to port 3. The PM fiber circulator is widely used in 2μm optical systems where polarization maintaining characteristics are needed.
