Product ID: 7008


1310nm Polarization Maintaining Fiber Optic Isolator with PM1550 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.
