In Line Faraday Rotator
The In-line Faraday Rotator rotates the polarization of the input light by 45 degrees. It performs with low insertion loss, high extinction ratio, high return loss and excellent environmental stability. It is used in sensors, circulators, amplifiers, lasers, etc. It is a bi-directional device.
