Multimode WDM for sensing applications

SEDI-ATI’s multimode wavelength division multiplexers are manufactured using a proprietary process based on a dichroïc filter directly deposited onto the optical fiber.

This unique manufacturing method ensures a robust construction allowing a bi-directionnal or dual transmission on a single multimode fiber.

The CP-MXC series can be made with a wide variety of optical fibers including graded-index fibers and large core step-index fibers up to 400 μm core diameter.

The dichroïc filter is fully customizable for a variety of UV, VIS or IR applications.

The CP-MXC is particularly suitable for sensing and fluorescence applications. It can also be adapted to operate in a wider temperature range to meet the requirements for geophysics or space for instance.

We offer standard packages in plastic material and can also propose a ruggedized package upon request: resistance to shocks, vibrations, accelerations, outgassing, and power.

Our multimode WDMs can be terminated with ST, SC, FC, or SMA connectors. Other connectors are available upon request.

Please contact us to discuss your specific requirements.
