Product Details

The 4 port mini 1310nm, 1550nm Polarization Insensitive Optical 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 optic circulator is widely used in optical fiber networks and fiber instruments. It features compact size.
