1310nm Polarization Maintaining Faraday Rotator Mirror
The 1310nm Polarization Maintaining Faraday Rotator Mirror is a PM fiber-pigtailed reflective device designed for polarization-maintaining optical systems. It rotates the polarization state of the reflected light by 90° relative to the incident light through a 45° single-pass Faraday rotation, helping reduce polarization fluctuations caused by thermal and mechanical disturbances in optical fiber systems.
Built with PM1300 polarization maintaining fiber, this 1310nm PM Faraday rotator mirror provides low insertion loss, high extinction ratio, compact structure, and stable long-term performance. The fiber slow axis is aligned to the connector key by default, enabling reliable integration into PM fiber assemblies. It is suitable for fiber lasers, fiber amplifiers, fiber optic sensing systems, fiber interferometers, and other polarization-sensitive applications requiring stable reflection and polarization control at 1310nm.
