1310nm 1550nm 2x1 Three-port Single-mode Fiber Circulator Can be Customized
A three-port fiber optic circulator is a multi-port non-reciprocal optical device in which 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.
We can produce three-port, four-port fiber circulators with different powers and different wavelengths. Our products are widely used in fiber lasers, instrumentation, dispersion compensation devices, fiber sensing, scientific research and other fields.

1. The temperature measurement environment is 25℃;
2. The above data does not include connectors. If connectors are added, the insertion loss will increase by 0.3dB and the return loss will decrease by 5dB. |
