Description
The 2050nm Fiber Optic Faraday Mirror is a high-performance optical component specifically designed to provide robust polarization control in advanced fiber optic systems. The Faraday Mirror is a passive device that provides 45- or 90-degree rotation regarding to the polarization state of the input light. It is a fiber optic polarization rotation mirror designed for fiber optic networks and measurement applications. Leveraging the Faraday effect, this mirror reflects light with a 90° polarization rotation, effectively canceling out birefringence and polarization-mode dispersion in fiber links. This results in improved signal stability, phase coherence, and enhanced measurement accuracy.
Operating at the 2050nm wavelength, this Faraday mirror is ideal for use in mid-infrared fiber laser systems, precision interferometry, optical sensing, and advanced communication networks. Its compact, all-fiber construction ensures seamless integration into PM or SM fiber setups. With excellent return loss, low insertion loss, and outstanding environmental stability, this device provides consistent, maintenance-free performance in both lab and field environments.
The device can help to eliminate polarization sensitivity of an optical fiber system. Applications include eliminating polarization induced fluctuations in fiber interferometers, Brillouin amplifier systems, fiber laser systems, and fiber optic antenna remoting systems. Our Faraday Mirror is optical path epoxy free and thus offers low insertion loss and high temperature stability.
If you require custom fiber types, connectorization, or handling power specifications, customization options are readily available upon request.
