Faraday Rotator Mirrors

Product Description

Our Faraday Rotator Mirrors offer engineers an inexpensive means of compensating for thermal or mechanical disturbances that affect the polarization of single-mode fiber, and ultimately the performance of many systems. These passive components eliminate polarization-induced fringe fading in interferometers and sensors, and can also optimize gain for EDFAs.
