The GK-FCIR Series Broadband 1310 nm 3-Port Circulator is a sophisticated optical device designed for high-efficiency signal routing and reliable performance in advanced communication systems. Operating at a center wavelength of 1310 nm, this compact circulator provides precise routing of optical signals from port 1 to port 2, and from port 2 to port 3, making it ideal for various network configurations and applications.

This circulator excels in performance with a maximum insertion loss of just 1 dB, ensuring minimal signal attenuation. It delivers exceptional isolation of 35 dB, which is critical for preventing cross-talk and maintaining signal integrity across different ports. The device features a low polarization-dependent loss (PDL) of 0.1 dB, which ensures consistent performance regardless of signal polarization.

Designed for superior environmental stability, the GK-FCIR Series operates reliably across a broad temperature range from -5°C to +70°C and can handle an optical power of up to 300 mW. Its construction supports a maximum tensile load of 5 N, adding to its robustness in various deployment scenarios. With a return loss of 55 dB and minimal crosstalk, this circulator is highly effective in high-demand environments such as telecommunications networks, optical monitoring systems, and data transmission applications, where precision and reliability are paramount.
