Polarization-Insensitive Optical Isolator

SOPO's 1310nm 1550nm Single stage/Dual stage Polarization-Insensitive Optical Isolator utilizes Faraday effect of Magneto optical crystal. It guides optical light in one direction and eliminates back reflection and backscattering in the reverse direction at any polarization state. The unique manufacturing process and optical path epoxy-free design enhance the device's high power handling capability. The devices are characterized by high performance, high reliability, and low cost. It has been widely used in EDFAs, Raman amplifiers, DWDM systems, Fiber lasers, transmitters, and another fiber optic communication equipment to suppress back reflection and backscattering.
