The GKER Photonics GK-FCIR Series 4-Port Polarization Insensitive Mini Fiber Optic Circulator is a high-performance, compact lightwave component designed to manage signal routing in advanced optical networks. This circulator directs incoming signals from Port 1 to Port 2, Port 2 to Port 3, and Port 3 to Port 4, ensuring efficient and precise signal flow. The device is engineered to deliver superior performance with minimal signal loss and high isolation, making it ideal for applications that require reliable signal integrity.

The circulator boasts high isolation, a low insertion loss of 0.7 dB, and low polarization dependent loss (PDL) and polarization mode dispersion (PMD). It operates efficiently across a broad temperature range and offers excellent environmental stability, ensuring consistent performance even in demanding conditions. Designed for use in dense wavelength division multiplexing (DWDM) systems, high-speed data communication networks, and bi-directional communication systems, this circulator is a crucial component for modern optical networks that demand reliability and precision.

The GK-FCIR Series is compatible with standard SMF-28 fiber and features a robust build that supports high optical power handling and minimal cross-talk, making it a versatile choice for various high-speed and high-capacity optical applications.
