635nm Red Fiber Optic Isolator Fiber Optical Device

Product ID: 7062


635nm Red Fiber Optic Isolator Fiber Optical Device

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 optic isolators are used to protect the light source from adverse effects caused by back reflections or signals; back reflections can damage the laser or cause it to mode-hop, amplitude change, or frequency shift. 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 power tolerance. Isolators with different wavelengths, powers, and optical fibers can be customized according to user needs. The products are widely used in fiber lasers, fiber amplifiers, laser communications, fiber sensing, Scientific research and other fields.
