Product Description

Irreversible Unidirectional Three-Port Device
Low Insertion Loss, High Isolation, High Stability and Reliability, Compact Structure
Multiple Center Wavelengths Available
Applications: Fiber Optic Sensors, Fiber Amplifiers, Fiber Lasers, Optical Communications, etc.

LBTEK’s fiber optic circulator is a three-port non-reciprocal optical device where light can only propagate in one direction. If the signal is input from port 1, it outputs from port 2; if the signal is input from port 2, it outputs from port 3, with very low output loss. When light is input from port 2, the loss is high when output from port 1, and similarly, when light is input from port 3, the loss is also high when output from ports 1 and 2. Fiber optic circulators are widely used in fiber lasers, add-drop multiplexers, bidirectional pumping systems, dispersion compensation devices, fiber optic sensors, scientific research, and other fields. LBTEK offers customization services, including three-port and four-port fiber optic circulators with different powers and wavelengths. For specific customization needs, please contact LBTEK technical support.
