4-port 1550nm Polarization Maintaining Optical Circulator

  • Wavelength: or Custom Wavelength 1625nm 1550nm 1480nm 1310nm
  • Handling Power: or Custom Handling Power 500mW
  • Fiber Type: Polarization Maintaining (PM) Panda Fiber
Product Details

  The 4 port 1550nm 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, port 2 to port 3, and port 3 to port 4. The PM fiber circulator is widely used in optical fiber networks and amplifiers where polarization maintaining characteristics are needed. High Power handling is available upon request.
