Origin
China

The online Faraday rotator mirror can reflect the incident light polarization state (SOP) at a 90° orthogonal polarization direction. It utilizes the magnetic rotation principle of the Faraday effect, with a single rotation of 45°, followed by a second reflection through the rear flat mirror to achieve a total rotation of 90°. This product features low insertion loss, high return loss, high extinction ratio, and excellent environmental stability and reliability, making it ideal for minimizing changes in fiber vibration caused by thermal and mechanical movements.
