product description
The GKER Photonics 4-Port Polarization Maintaining Circulator (GK-DPMCIR Series) is a versatile and high-performance optical component designed for demanding fiber optic applications. This circulator efficiently routes signals in a 2×2 configuration: incoming signals from Port 1 are directed to Port 2, signals from Port 2 are directed to Port 3, and signals from Port 3 are directed to Port 4. This advanced circulator is engineered for optimal performance in the 2000 nm wavelength range and is available in two types, each providing specific operating parameters to suit various needs.
Key features of the GK-DPMCIR Series include high isolation, low insertion loss, and a high extinction ratio, ensuring minimal signal loss and interference, even in complex optical systems. Its robust design offers excellent environmental stability, making it suitable for a wide range of operating conditions.
The circulator is available with either PM 1550 Panda Fiber or PM 1950 Panda Fiber, providing flexibility in handling different wavelength ranges. It is an ideal choice for applications requiring precise signal routing and high-power handling capabilities.
