1550±50nm Polarization Maintaining Optical Circulator

  • Wavelength: 1550nm or Custom Wavelength
  • Handling Power: 500mW or Custom Handling Power
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

The 3 port 1550±50nm broadband 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 optical fiber networks and amplifiers where polarization maintaining characteristics are needed. It features broadband and high Power handling is available upon request.
