These multimode step-index launch optical fibers are designed with low 0.22 numerical aperture — an extra low 0.15 NA is also available. These configurations can handle peak power delivery approaching 1GW/cm2. The coating offers easy mechanical stripping and is compatible with either carbon or PYROCOAT® polyimide coatings, or both, when various combinations of hermeticity and/or high temperature resistance are needed. Launch fibers can also be metalized for hermetic sealing into opto-electronic devices.

*F10017 Attenuation: Most of the attenuation is induced by the spooling of this low NA product.  Observed loss in application will be less.
