What is  fiber circulator?

Three-port fiber circulator is a multi-port non-reciprocal optical device, and light can only propagate in one direction. If a signal is input from port 1, it will be output from port 2; if a signal is input from port 2, it will be output from port 3, and the output loss is very small; when light is input from port 2, the loss is very large when it is output from port 1, and similarly, when light is input from port 3, the loss is also very large when it is output from ports 1 and 2.

A series of fiber circulators with different short wavelengths, different powers, and different optical fibers such as 532 /633/670/780/808/830/850/915/980nm can be customized according to user needs. The products are widely used in fiber lasers, fiber amplifiers, underwater laser communications, medical treatment, fiber optic sensing, scientific research and other fields.
