1550nm Polarization Maintaining Faraday Rotator Mirror
The 1550nm Polarization Maintaining Faraday Rotator Mirror is a PM fiber-pigtailed reflective device designed for polarization-maintaining optical systems. By utilizing a 45° single-pass Faraday rotation, the reflected light undergoes a total 90° polarization rotation relative to the incident light, helping compensate for polarization fluctuations caused by environmental disturbances in optical fibers.
Built with PM1550 polarization maintaining fiber, this device offers low insertion loss, high extinction ratio, compact size, and excellent long-term stability. The slow axis is aligned to the connector key by default, ensuring reliable integration into PM fiber networks. It is widely used in fiber lasers, fiber amplifiers, fiber optic sensing systems, interferometers, and other polarization-sensitive applications where stable polarization control and reflection are required.
