We provide a wide selection of fiber optical isolators/circulators covering most application scenarios. These include narrowband and broadband configurations that operate in spectral ranges from 350 nm to 2100 nm with both polarization-independent and polarization maintain versions and high-power options up to 40W. We specialize in high-performance isolators beyond the current state-of-the-art, utilizing our patented technologies. Many isolators are in volume production, offering an unmatched cost advantage. We specialize in integrated power monitors for both forward and backward lights. We also offer custom isolator designs that can combine the best features across our entire isolator family. The fiber optical isolators are categorized below into three wavelength ranges using different magneto-optical materials.
