1550 nm band
bend insensitive
PANDA
(Bending radius 5 mm)
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 1550 nm band (near infrared light)
・Product for small bending radius (R5 mm)
・Excellent optical properties such as low attenuation and low polarization crosstalk
・RoHS compliant
