Produts Details

Product Name: 4-Port Circulator


The 4-port Mini Fiber Optic Circulator is a compact, high performance lightwave component that routes incoming signals from Port 1 to Port 2, Port 2 to Port 3, Port 3 to Port 4. The component provides high isolation, low insertion loss, low PDL, low PMD and excellent environmental stability. It is widely used in combination with fiber gratings and other reflective components in DWDM systems, high speed systems and bi-direction communication systems.
