Fiber Optical Isolators / Circulators

We offer a comprehensive selection of fiber optic isolators and circulators, perfected over 25 years of volume production to cover most application scenarios. Our products include both narrowband and broadband configurations, operating in spectral ranges from 350 nm to 2100 nm, with options for polarization-independent and polarization-maintaining versions and high-power capabilities up to KW. We specialize in high-performance isolators that exceed the current state-of-the-art, including the ultra-broad band of 200nm, integrated power monitors for both forward and backward light. Custom isolator designs are also available, allowing you to combine the best features from our entire isolator family. Our fiber optic isolators are categorized into three wavelength ranges, each utilizing different magneto-optical materials to best suit your specific needs.
