Description
The GK-FCIR Series Polarization Insensitive Mini Fiber Circulator by GKER Photonics Co., Ltd is a compact, high-performance optical device designed for efficient signal routing in modern fiber optic networks. Engineered to route optical signals from Port 1 to Port 2 and from Port 2 to Port 3, it features ultra-low insertion loss, high isolation, and minimal polarization dependent loss (PDL). Its small form factor (5.5 × 50 mm) makes it ideal for space-constrained optical modules, while its robust design ensures excellent stability across a wide operating temperature range from -5°C to +70°C.
This circulator is particularly well-suited for Dense Wavelength Division Multiplexing (DWDM) systems, high-speed communication platforms, and bi-directional transmission systems. With a broad operating wavelength range (±20 nm from center), it supports both 1310 nm and 1550 nm applications. Constructed with SMF-28 fiber, it handles up to 300 mW continuous wave optical power, ensuring reliability for demanding communication environments.
Custom configurations, fiber types, and connector options are available upon request, making the GK-FCIR Series a versatile solution for advanced photonics systems.
