1625nm 3-port Optical Circulator

  • Wavelength: 1625nm
  • Handling Power: 500mW
  • Fiber Type: Single Mode Fiber G657A Fiber
Product Details

  The 3 port 1625nm 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, and port 2 to port 3. The fiber circulator is widely used in optical fiber networks and fiber instruments. High Power handling is available upon request.
