1x2 achromatic fiber optic multimode couplers

SEDI-ATI’s 1×2 achromatic fiber-optic multimode couplers have been designed for applications where wideband and achromaticity are required at an attractive cost.

Besides, they can be made with any Graded Index fiber types such as GI50/125 μm or GI62.5/125 μm. We can also offer GI100/140 μm upon request.

Please contact us to discuss your specific requirements as our achromatic fiber-optic multimode couplers can be customized with different coupling ratios, different fiber lengths, and even 2×2 configurations.
