The LBTEK single-mode fiber optic isolator primarily utilizes the Faraday effect of magneto-optic crystals to isolate reflected light, allowing light to travel only in one direction. It is a passive magneto-optic device. Fiber optic isolators are used to prevent light sources from being adversely affected by backward reflection or signals. Backward reflection can damage lasers or cause mode hopping, amplitude variations, or frequency shifts. In high-power applications, backward reflection can also lead to instability and power spikes. LBTEK linear fiber optic isolators offer high isolation, low insertion loss, and high power handling capabilities. They are widely used in fiber lasers, fiber amplifiers, laser communications, fiber sensing, and scientific research applications. LBTEK provides customization services, including isolators with different wavelengths, power ratings, and fiber types. For specific customization requirements, please contact us.
LBTEK polarization-maintaining single-mode fiber optic isolators are available in multiple center wavelengths ranging from 780 nm to 2000 nm, with a maximum power handling of up to 10W. They come with polarization-maintaining fiber, making them suitable for polarization-maintaining optical transmission systems. Low-power versions are equipped with FC/APC connectors, while high-power versions are available with bare fiber and no connectors. Each isolator undergoes rigorous testing and comes with a test report to ensure product performance. The input sleeve is marked with a black marker for easy identification, and the incident direction is also labeled on the casing. LBTEK polarization-maintaining single-mode fiber optic isolators offer customization options, including center wavelength, bandwidth, power, and fiber type.
