850 nm 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
・Polarization maintaining fiber capable of transmission in 850 nm band （near infrared light）
・Excellent optical properties such as low attenuation and low polarization crosstalk
・RoHS compliant
