Sngle Mode & Polarization Maintaining 3 and 4 Port Mini Fiber optic Circulators.
The Mini Fiber optic Circulator is a compact, high performance component that transmits the incoming signal from port 1 to port 2, and another incoming signal from port 2 to port 3 simultaneously. The component provides high isolation, low insertion loss 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.
