780nm Polarization Maintaining PM Fiber Isolator with PM780 Fiber
Optical fiber isolators mainly use the Faraday effect of magneto-optical crystals to isolate reflected light and are passive magneto-optical devices that only allow light to transmit in one direction. Fiber isolators are used to protect the light source from unwanted effects caused by back reflections or signals; back reflections can damage the laser or cause it to mode hop, change in amplitude or shift in frequency. In high-power applications, backreflections can also cause instability and power spikes.
The isolators produced by TaorLab have high isolation, low insertion loss, and high withstand power. Isolators with different wavelengths, powers, and fibers can be customized according to user needs. The products are widely used in fiber lasers, fiber amplifiers, laser communications, fiber optic sensors, Scientific research and other fields.

*The temperature measurement environment is 25℃;
*The above data does not include connectors. If more connectors are added, the insertion loss increases by 0.5dB, the return loss decreases by 5dB, and the extinction ratio of polarization-maintaining products decreases by 2dB. The default mode is that the slow axis works and the fast axis cuts off.
