850 nm 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 the 850 nm band, which corresponds to near-infrared light.
Features
・Suitable for 850 nm band
・Low polarization crosstalk and low attenuation
・RoHS compliant
