4 Ports Optical Circulator
In the four-port circulator, if the signal is input from port 1, it is output from port 2; while the signal is input from port 2, it is output from port 3, and the signal is input from port 3, it is output from port 4. The product is widely used in fiber lasers, optical division and multiplexing, bidirectional pumping systems, dispersion compensation devices, fiber sensing, scientific research and other fields.
