1x2 large core fiber optic multimode couplers
SEDI-ATI’s large core fiber-optic multimode couplers are ideal for spectroscopy applications where large core optical fibers are required.
They can be made with any large core step-index fiber types from 100 μm to 1000 μm core diameters, including Launch fibers (LCH) and Hard-Clad Silica fibers (HCS).
Please contact us to discuss your specific requirements as we can also offer multimode large core fiber-optic couplers with different coupling ratios, different fiber lengths, special packaging for high-temperature applications, higher directivity, and 1xN configurations.
