Choosing the right optical fiber takes more than a wavelength
Identifying the optimal fiber depends on much more than the target emission wavelength. Power handling, pump configuration, core architecture, polarization extinction, and operating environment all influence fiber performance.
That’s where Exail’s expertise makes the difference. Our specialists help you identify the right solution across our broad specialty fiber portfolio — including active rare-earth doped, high-birefringence PM, and radiation-resistant fibers.
We design, manufacture, and characterize our fibers in-house, giving us full control from glass composition to final performance measurement. This ensures batch-to-batch repeatability and expert technical guidance tailored to your system requirements.
