Product Details

The 3 port 760 780 790 nm polarization maintaining (PM) optical circulator is a fiber optic component 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.
