1550nm 4-port Optical Circulator

  • Wavelength: 1310nm 1480nm 1550nm
  • Handling Power: 500mW
  • Fiber Type: Single Mode Fiber
Product Details

  The 4 port 1550nm Polarization Insensitive Optical Fiber Circulator is a fiber optic componet built with single mode 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 port3 to port4. The fiber circulator is widely used in optical fiber networks and fiber instruments. High Power handling is available upon request.
