The Reduced Cladding Fiber Faraday Mirror (GK-RCFM Series) by GKER Photonics is a sophisticated passive optical device designed to offer precise 90-degree polarization rotation without being affected by the input light's polarization state. This advanced Faraday mirror is engineered for applications requiring high performance and stability in optical systems. It features excellent environmental stability and minimal insertion loss, making it an ideal choice for integration into various optical setups.

The GK-RCFM Series is particularly beneficial in compact optical amplifiers, where space constraints necessitate the use of highly efficient components. It also finds extensive application in Dense Wavelength Division Multiplexing (DWDM) systems, where stable performance across multiple wavelengths is crucial. In addition, the device is suitable for optical sensors and compact optical circuits, where it helps to reduce polarization-related issues, thereby enhancing the overall accuracy and reliability of the system.

With a typical insertion loss of 1.0 dB and a maximum insertion loss of 1.2 dB, the GK-RCFM Series ensures high efficiency and minimal signal degradation. The mirror maintains a Faraday rotation angle of 45 degrees with a maximum rotation angle tolerance of ±3 degrees at the center wavelength of 1550 nm. It also offers a low maximum polarization-dependent loss of 0.05 dB, ensuring consistent performance across varying conditions. Designed for high optical power handling up to 300 mW and robust against tensile loads up to 5 N, the GK-RCFM Series operates reliably within temperatures ranging from -5°C to +70°C and can be stored from -40°C to +85°C.
