980nm 3-port Polarization Maintaining PM Fiber Optic Circulator

Product ID: 7110


980nm 3-port Polarization Maintaining PM Fiber Optic Circulator

The 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 the output loss is very small; when the light is input from port 2, the loss is very large when it is output from port 1. Similarly, when light is input from port 3, the loss when output from ports 1 and 2 is also very large.

TaorLab can produce three-port, four-port, different power and different wavelength fiber optic circulators, which are widely used in fiber lasers, instrumentation, dispersion compensation devices, fiber optic sensing, scientific research and other fields.
