0.41 μm band
PANDA
Fujikura PANDA fibers (Polarization-maintaining AND Absorption-reducing fiber) have a superior optical property in polarization-maintaining because of the symmetrical accuracy in cross section and the uniform constitution of stress applying parts. Based on Fujikura's fiber technology, PANDA fibers have a universal quality with not only low polarization-crosstalk and low attenuation but also the broad suitability for fusion-splice or optical connector. This PANDA fiber is compatible with 0.41 μm band (violet-blue light), making it suitable for high-power light transmission because of its pure silica core.
Features
・Suitable for 0.41 µm band
