Product description

Designed for space-constrained applications, this coupler is manufactured using 80 μm cladding fiber, enabling low fiber bend radius within modules without compromising mechanical integrity.

With splitting ratios from 1:99 up to 50:50, the standard wavelengths of operation are the C, L, C+L, or S bands for fiber amplifier applications, with other wavelengths available upon request for applications such as sensing, fiber lasers, and fiber optic gyroscopes. Please get in touch with us for more information.
