Fiber Isolator Series

Fiber isolators are essential passive optical components designed to allow light transmission in one direction while effectively blocking reverse reflections, ensuring the stability and protection of sensitive optical systems.

At Kernstech, our Fiber Isolator Series includes a wide range of high-performance solutions such as polarization maintaining (PM) isolators, polarization insensitive isolators, and high power fiber isolators. These devices are engineered with low insertion loss, high isolation, and excellent reliability to meet the demanding requirements of modern fiber optic applications.

Our fiber optic isolators support multiple operating wavelengths including 1310nm, 1550nm, 1064nm, and 1030nm, and are available in compact and customizable designs for seamless integration into various systems.

They are widely used in fiber laser systems, optical communication networks, fiber optic sensors, test instruments, and scientific research applications, where preventing back reflection is critical for maintaining signal integrity and system performance.

With strong customization capabilities, Kernstech provides tailored isolator solutions to match your specific power handling, fiber type, and packaging requirements.
