Optical Circulator
Description
The 3 port optical circulator is a compact high performance lightwave component that transmits the incoming signal from port 1 to port 2, while transmitting another incoming signal from port 2 to port 3. The component provides high isolation, low insertion loss, high extinction ratio, and excellent environment stability.
