Single Mode Fiber Optic Circulators

   An optical circulator is a component that can be used to separate optical power that travels in opposite directions in one single fiber. An optical circulator is a three-port device that allows light to travel in only one direction from port 1 to port 2, then from port 2 to port 3. Gould offers single mode fiber optic circulators with low optical loss, high isolation and low polarization dependent loss (PDL).
