980nm single-mode fiber isolator

Fiber isolators are passive magneto-optical devices that mainly use the Faraday effect of magneto-optical crystals to isolate reflected light and only allow light to be transmitted in a single direction. Fiber isolators are used to prevent light sources from being adversely affected by back reflections or signals; back reflections may damage the laser or cause it to hop mode, change amplitude or frequency shift. In high-power applications, back reflections can also cause instability and power spikes. The isolators produced by Idealphotonics have high isolation, low insertion loss, and high withstand power. Isolators of 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.
