PM 1×4 Magneto-Optic Switch
The PM 1×4 Magneto-Optic Switch is connected to the optical path by connecting or blocking the optical signal. the switch has non-mechanical configurations and activated via an electrical control signal. the switch also has build-in circulator and isolator functions. Products are widely used in aerospace and military equipment.
