1x2 multimode high directivity fiber optic couplers

SEDI-ATI’s multimode high directivity fiber-optic couplers are ideal for optical metrology and sensing applications where the dynamic range of the sensor is a key parameter.

They can be made with any Graded Index fiber types such as GI50/125 μm with directivity as high as > 55 dB or GI62.5/125 μm with directivity as high as > 45 dB.

For high-power UV applications, we have developed the HDS series which can handle as much as 2 W @ 420 nm.

Our multimode high directivity fiber-optic couplers are also available with different coupling ratios and fiber lengths upon request.

Please contact us to discuss your specific requirements.
