PM fiber 980nm 20W High power circulator
The optical circulator is a component that can be used to separate optical power that travels in opposite directions in one single fiber. A fiber optic 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. Fiber Circulators are known for their reliability in increasing transmission capacity of existing networks. applications of optical circulators are expanding rapidly from communication systems to medical and imaging fields such as OCT applications.
