0.41 μm band
PANDA
Fujikura PANDA fibers 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.
Features
・0.41μm band (violet-blue light) polarization maintaining fiber
・Low attenuation and low polarization crosstalk
・Pure silica core suitable for high energy light transmission
・RoHS compliant
