1310nm 1550nm 2X2 4Port SM Fiber Optic Circulator High Isolation Circulator
The 1550nm 4-port fiber optic circulator is a multi-port non-reciprocal optical device, and light can only propagate in one direction. If the signal is input from port 1, it will be output from port 2; if the signal is input from port 2, it will be output from port 3, and its output loss is very small; when the light is input from port 2, the loss when output from port 1 is very large. Similarly, when light is input from port 3, the loss when output from ports 1 and 2 is also very large. It can produce three-port, four-port fiber optic circulators with different powers and different wavelengths. The products are widely used in fiber lasers, add-drop multiplexers, bidirectional pump systems, dispersion compensation devices, fiber optic sensing, scientific research and other fields.
